Review: Dragon NaturallySpeaking 11.5

Nuance Dragon NaturallySpeaking is a voice dictation system for Windows, and there is a similar but not identical version available for the Mac. I have been trying version 11.5 in its Premium edition.

Voice recognition is interesting on several levels. Dictation can be quicker than typing, avoids repetitive strain injury, and for some users may be the only practical way to input text and control a computer.

Voice control is also a computing aspiration. In science fiction novels and films from 40 or 50 years ago, the characters use voice to interact with computers like Asimov’s Multivac or Kubrick’s HAL in 2001: A Space Odyssey as a matter of course. It has proved a difficult problem though, and even the best voice recognition systems are frustrating to work with, since mistakes are frequent and corrections difficult.

That said, Dragon NaturallySpeaking is the best I have used. Let me answer a few questions:

Q: Is Dragon good enough to use for real work?

A: Yes. Fire up Dragon, then Microsoft Word, start dictating, and you can write a document without too much pain. Of course there will be errors, but Dragon has an excellent correction system. In the following example, I said “The reason” but Dragon heard “Losing”. I then spoke the command “Select losing” and Dragon popped up a selection box.

Now I just have to say “Choose 1” and the error will be fixed.

It is not always so easy, and you may have to spell words like place names and specialist vocabulary, but Dragon learns and you get better at dictating, so perseverance pays.

Dragon has a sidebar which is great when you are learning the system, as it shows brief contextual help for the most commonly used commands. It does occupy significant screen space, so best used when you have a large screen or more than one display.

Q: What is the key to success with dictation?

First, use a good microphone. Some editions of Dragon come with a Plantronics Bluetooth headset, which is ideal for the task. Trying to dictate using the mic built into a laptop, or one of those cheap gaming mics, will only lead to frustration.

Second, be patient. Your first day or two with Dragon will be frustrating, but it gets better.

A quiet room also helps, but with a headset this is not so critical.

Q: Is Dragon good enough that you would use it by choice, even when you could use keyboard and mouse?

For me, not yet. I type professionally, so I am pretty fast, and I do find Dragon gets in the way. If I could reel off a few thousand words in one blast, I might use Dragon, but in practice I find I need to task-switch frequently, checking a fact, searching the web, finding a screenshot, or listening to an interview. You can do almost anything in Windows using Dragon, but using a mouse and and keyboard is much quicker. If you use Dragon just for dictation that is fine, though you do have to set Dragon to stop listening when you are performing other tasks, otherwise Dragon will do something unexpected.

Work patterns vary, and some voices are easier than others for Dragon to interpret, so this is a matter of individual preference.

Q: Do you need Dragon when Windows has its own voice recognition system?

I did a quick test. I read the following paragraph, from a guide book that happens to be close by:

Original:

This little book is not properly a “guide” but rather a collection of random notes and thoughts, and I have published it mainly as a souvenir for those who make a short journey from Wroxham with Broads Tours.

Windows 7:

This little book it is not properly A “guide” but rather a collection of London dates and courts, and I had published in mainly as a souvenir for those who make a short journey from locks on withdrawn schools.

Dragon:

This little book is not properly a “guide” but rather a collection of random notes and thoughts, and I have published it mainly as a souvenir for those who make a short journey from locks and with Broads Tours.

Not a rigorous test; but with my voice and on this particular passage Dragon is well ahead, and that accords with my general impression. I do think the Windows system is usable, but the extra cost of Dragon is worth it if you expect to use dictation frequently.

Q: Any other snags with Dragon?

Yes. Dragon hooks deeply into Windows, as it must do in order to control things like window switching and mouse movement, and I saw an impact on performance and stability. I suspect this can be improved by fine-tuning Dragon’s configuration and by keeping Windows as plain as possible. It also seems to work much better with software for which it is specifically designed, such as Microsoft Office, than with generic text input into software it does not know about, such as Windows Live Writer.

Q: What is new in version 11.5?

Dragon NaturallySpeaking 11.5 is a free upgrade from 11. The most obvious new feature from 11 is that you can use an iPhone as a remote wi-fi microphone. I tried this, which requires creating a new profile specifically for the purpose, and found it works nearly as well as with the Plantronics headset. However, the headset is a lot more convenient so I am not sure what is the benefit.

There are also new commands including “Post to Twitter” and “Post to Facebook”, and both the user interface and the voice recognition engine have been fine-tuned in this version.

Finally, version 11.5 specifically supports Windows 7 SP1 and Internet Explorer 9.

Q: Any other features worth mentioning?

The Premium edition has a transcription feature. No, this will not successfully interpret your recorded interview, though I suppose this might work in ideal circumstances. Rather, it is intended to let you dictate into a recording device for transcription later. This is an interesting way of working. It is easier to pause and restart a recorder than to interrupt a live dictation session, and Dragon can take more time over analysing a recording than when it has to keep up with your voice.

Concluding remarks

Nuance Dragon NaturallySpeaking gets significantly better with each new version, tipping me further towards the point where I may start using it in preference to typing. It is not only a matter of improved algorithms, but also more powerful hardware that enables Dragon to do more intensive processing. Although I am not quite ready to use it myself day to day, I think this is a brilliant product, and would not hesitate to recommend it. I also think it is inevitable that voice dictation will eventually become the norm for text input, at least in quiet environments, as the technology continues to improve.

Kingston Wi-Drive extends iOS storage, but not hassle-free

I have been trying out the Kingston Wi-Drive, which expands the storage of an iOS device using a pocketable wireless solid-state drive.

image

The unit is about the size of a mobile phone, but smoother and lighter, and available with capacity of 16GB or 32GB.

The drive comes with a minimalist instruction leaflet which tells you to charge it by attaching the USB cable to a PC or Mac, add content by accessing it as an external drive, and then when charged, download and run the free Wi-Drive app on your iPad or iPhone.

I got this working without too much trouble. I added a movie to the drive and was able to watch it on an iPad, which is handy given that there is no DVD drive, though if it was sourced from a DVD you have to work out how to rip the DVD to a file first. I also added some documents and pictures, and was able to view these on iOS without any issues.

image

The app seems to be designed primarily for iPhone, which means it looks a little odd on an iPad, though it does run full-screen. There is a thumbnail view, for images, and for documents there is an option to open them in apps that understand the file format. For example, I could open a Word 2010 document in Pages.

So far so good; but I found some annoyances. The first is that when you connect to the Wi-Drive, you are no longer connected to the Internet unless you also have 3G. The solution is to go into the Wi-Drive settings and configure your normal wi-fi connection as a bridge. The leaflet does not mention this, but it is explained here.

The bridge did not work at first. I had to change my Netgear router so that it is WPA 2 only, rather than supporting both WPA and WPA 2. This is mentioned in the FAQ:

Wi-Drive’s bridge function supports a single security protocol only: WEP, WPA, or WPA2. These may also appear as WPA ONLY, WPA2 ONLY, etc. Wi-Drive does NOT support mixed mode.

I also configured security on the Wi-Drive wi-fi connection. By default, it is wide open to your neighbours; and if you have the bridge enabled, bypasses the security of your home wi-fi connection as well. On the other hand, the fact that up to three users can connect is a good thing if, for example, you wanted to share some files with friends or colleagues at a meeting.

If you are using the device on the road, in a cafe or airport for example, it would be difficult to connect to the internet as well as to the drive. If you are flying, the airline will probably not allow you to use the Wi-Drive.

Most annoying is that when the device is connected to a computer, the contents become inaccessible. Even connecting to a USB charger seems to be enough to disable it. When it is not connected to a computer, the battery starts running down; it only lasts 4 hours.

This means that you should not think of the Wi-Drive as permanently attached storage. Rather, think of it as something you can switch on when needed.

Poking around on the drive, I noticed that it has the Apache web server installed. When the bridge is operating, you can browse to the device from a web browser on your computer and access the contents or change the settings.

image

This is a handy device; but it could be better. I would like to see a memory card slot – and Kingston would benefit as it sells memory cards – as well as a longer battery life. Kingston also needs to fix it so you can use it on iOS while it is connected to a computer and charging. The Wi-Drive app could do with a bit more polish too, particularly the iPad version.

As it is, the Wi-Drive is great if it exactly fits your need, but make sure you can live with it before parting with your money.

Drobo storage devices: beyond RAID

1 Comment

I attended Digital Winter in London this week, an event where gadgets are shown to the press.

image

One that caught my eye was the Drobo range of storage devices. The market is saturated with external storage solutions, but Drobo has a neat system where you simply slot any 3.5” Sata drive – no drive bracket required – into one of its units and it will add it to a pool of storage. Drobo supports thin provisioning, which means you will typically create a volume on the pool that is bigger than the space actually available. When you are running out of space, a light on the unit will turn yellow, you buy another drive and slot it in. Presuming you have two or more drives, RAID-like resiliency is built in, though Drobo calls its system BeyondRAID because of its greater flexibility. There is even an option for dual disk redundancy, so that any two drives can fail without loss of data.

I was reminded of Microsoft’s new Storage Spaces in Windows Server 8 which offers some similar features, but of course is not yet available except in early preview.

Drobo boxes support USB, FireWire, and in the high-end models iSCSI.

image

The snag: prices start at €359,00 for the 4 Bay firewire and USB 2.0 model, and the one you really want, the 8-bay DroboPro with iSCSI, is €1359.00. In the business range, the 12-bay iSCSI SAN is €10,799 and supports SAS as well as Sata drives.

Document security and Apple iCloud

1 Comment

I have just set up iCloud on three Apple devices: a Mac, an iPad 2, and an iPhone 4.

image

On the iOS devices I was asked if I wanted to use iCloud, and when I agreed, watched as all my documents were transferred from the device to iCloud.com.

I then went to the iCloud website, signed in with my Apple ID – username and password – and saw that all my documents were there ready for download.

I also tried editing a document on the iPhone. In moments, the edited document was also updated on the iPad.

All very convenient; but I realised that I’d just sent up to the cloud a couple of documents that include information I do not want to share. How safe is it on iCloud? Does Apple encrypt the documents?

I looked at Apple’s iCloud information and on the support site and found nothing about security on a quick look, other than that traffic is SSL encrypted, so here are my own observations.

First, access to iCloud.com is protected only by the username and password which form your Apple ID. Sony recently reported a breach of 93,000 accounts on the PlayStation network, apparently based on a list of username/password combinations that a hacker found elsewhere. In other words, some other popular site(s) suffered a security breach, and the hacker automated an attack on the PlayStation Network on the assumption that the same credentials might be used there. The majority failed, but 93,000 succeeded, demonstrating that this is not a small risk.

Second, I wondered if I could mitigate the risk by encrypting my iCloud documents. I cannot find a way to set a password on a Pages document in iOS, but I can do so on the Mac. I password-protected a document, and then uploaded it to iCloud. Next, I opened this on the iPad. I was prompted for the password – good. However, I then modified the document in Pages on the iPad. This automatically updated the document on iCloud, but it was no longer password protected. I do not recall seeing a warning about the password protection being removed. It looks as if password protection does not iWork if you use iOS.

Third, I found this statement in Apple’s terms of service for iwork.com. It is repeated in the terms for MobileMe, and which I cannot yet find terms for iCloud.com it may well be the same there too:

Access to Your Account and Content

You acknowledge and agree that Apple may access, use, preserve and/or disclose your account information and Content if legally required to do so or if we have a good faith belief that such access, use, disclosure, or preservation is reasonably necessary to: (a) comply with legal process or request; (b) enforce these TOS, including investigation of any potential violation thereof; (c) detect, prevent or otherwise address security, fraud or technical issues; or (d) protect the rights, property or safety of Apple, its users or the public as required or permitted by law.

I guess what this means is that if you have confidential documents, iCloud.com is not a sensible place to keep them.

I would like to see some way of disabling cloud sync for specified documents, but as far as I can tell there is no such feature yet.

Further, if your Apple ID is the same username and password that you use on dozens of other sites on which you have been required to register, it would be worth changing it to something long and unique. I would also suggest reviewing the insecurity questions, which are not for your protection, but to reduce the number of password reset requests which support have to deal with. The best answers are those which are not true and therefore potentially discoverable, but made-up ones, as essentially these are secondary passwords.

New Sony PlayStation Network hack: not as bad as you may have heard

Sony’s Chief Security Officer Philip Reitinger has reported a new attack on the PlayStation network leading to headlines stating Sony hacked again. Has the company not learned from the incidents earlier this year?

Actually, it probably has; the new hacking attempt does not exploit any weakness in Sony’s network unless you consider any system reliant on username/password to be weak – not an unreasonable opinion, but given that the likes of Apple and Amazon and PayPal still use it, hardly fair to single out Sony.

If you read the statement carefully, it says that somebody obtained a large list of username/password pairs and ran them against Sony’s network. Further:

given that … the overwhelming majority of the pairs resulted in failed matching attempts, it is likely the data came from another source and not from our Networks

Because of the large number of PlayStation users, there were still 93,000 successful matches, which to its credit Sony says it detected – presumably there was a pattern to the attack, such as a limited range of source IP numbers or other evidence of automated log-in attempts.

If Sony is right, and the list of passwords came from another source, there is no reason why the hacker might not try the same list against other targets and this is not evidence of a weakness in the PlayStation network itself.

As Reitinger notes:

We want to take this opportunity to remind our consumers about the increasingly common threat of fraudulent activity online, as well as the importance of having a strong password and having a username/password combination that is not associated with other online services or sites. We encourage you to choose unique, hard-to-guess passwords and always look for unusual activity in your account.

It is good advice, though can be impractical if you have a very large number of online accounts. Something like PasswordSafe or Keypass is near-essential for managing them, if you are serious about maintaining numerous different combinations.

From what we know so far though, this is not evidence of continued weakness in the PlayStation network; rather, it is evidence of the continued prevalence of hacking attempts. Kudos to Sony for its open reporting.

Amazon Silk: fast cloud-powered browser, or a new way to mine your data?

3 Comments

Amazon announced its new range of Kindle devices today and the web is buzzing with debate about the impact of the new Android-based Kindle Fire tablet on Apple and others.

Amazon knows how to pile high and sell cheap, and can make money from content even if it gives away the hardware, so it is a strong contender in this space.

The real innovation announced today though was in the web browser. Amazon announced Silk, which splits the browser between your Kindle Fire and EC2 (Elastic Compute Cloud).

image

Amazon’s point: it can hold a massive cache of web content on EC2, as well as performing common-sense optimizations like scaling images to an appropriate size before sending them to your device.

Is this really new? Much of it sounds familiar, if you know about caching and proxies. Nevertheless, Amazon is in a strong position with its large cloud resource, and can design the web browser specifically for its cloud proxy. In addition, it knows the exact size and capability of the device. And perhaps its smart engineers have come up with better ways to cache. One feature is predictive caching – sending down the page it things you will visit next, before you actually go there.

There are some hard problems, as I have found in trying to optimize my own web site. Caching dynamic content, so that PHP script does not get executed by every browser request, is an obvious thing to do; but web pages draw content from multiple sources, including scripts that serve ad content that is meant to be targeted for the specific viewer. Optimizing that is harder.

It does also occur to me that a side-effect of Silk is that every single bit of browsing you do will go through Amazon and could potentially be mined for data about your browsing habits. Amazon, naturally, is well-placed to send you related ads from its own retail site. Amazon has not mentioned this aspect, but I am sure it has been thought about.

An ugly dialog from Spotify

I am a big fan of Spotify, mainly because it works so well. Search is near instant, playback is near instant.

I understood when, under pressure from the music industry, it limited the value of the free version by restricting the hours of play and the number of times you can play a specific track.

This is ugly though:

image

Spotify says:

From today, all new Spotify users will need to have a Facebook account to join Spotify. Think of it as like a virtual ‘passport’, designed to make the experience smoother and easier, with one less username and password to remember. You don’t need to connect to Facebook and if you do decide to, you can always control what you share and don’t share by changing your Spotify settings at any time.

Why care? Privacy? Because you might want Spotify but not Facebook?

I would put it another way. I am wary of putting Facebook at the centre of my Internet identity. If others follow Spotify’s example and the Web were to become useless unless you are logged into Facebook, that would give Facebook more power that I would like.

If for some reason you want to withdraw from Facebook, why should that affect your relationship with Spotify? It is an ugly dependency, and I hope that Spotify reconsiders.

Android tablets ahead of Apple iPad on Amazon

Following Gartner’s report on the expected dominance of Apple’s iPad2 in the tablet market throughout 2011 I took a quick look at Amazon’s sales and user ratings.

My guess is that Apple stores and direct sales online account for a large proportion of iPad sales, so no doubt the iPad is ahead overall. Even so, I was interested to find  the iPad at number 7 on Amazon.co.uk, not only below three cheap 7” cheapies from little-known brands, but also below the Asus EeePad Transformer and the Samsung Galaxy Tab 10.1, both of which are at iPad-like prices.

image

Buyers on Amazon.com seem to have less enthusiasm for the cheapies. At the time of writing, bargain prices have pushed HP’s discontinued TouchPad to number 1, followed by the EeePad and the Motorola XOOM. Apple iPad is at 4, with Galaxy Tab 10.1 at 5 and 6.

When you see nearly 500 user reviews and a four star average rating, as for the Eee Pad, it shows that these things really are selling and being enjoyed.

Of these I have only properly tried the TouchPad and the iPad. I did not much like the TouchPad, though apparently firmware updates have considerably improved it.

The closest I got to Windows on ARM at Microsoft BUILD 2011

A couple of the stands in the exhibition at Microsoft’s BUILD conference last week were showing Windows on ARM. This one was on the NVIDIA stand and was most likely running its Tegra 2 SoC (System on a Chip) though Tegra 3 (code-name Kal-El) is apparently now in production. The tablet was displayed under a plastic shroud which could only be lifted when someone from Microsoft was present, though I was able to get this snap of the machine sans shroud. I was not permitted to handle the machine.

image

I have blanked out part of the background because it was black on black.

My main observation: it looks just like the Intel version. This screen shows a Metro app running side by side with the Windows desktop, and showing the “charms” on the right.

Gartner reports that Apple will have the tablet market almost to itself in 2011 (73.4% market share). I believe Windows on ARM is critical to Microsoft’s strategy to compete. In principle, it should be cheaper and more efficient than an Intel device, and one that is more locked-down in the style to which Apple has made us accustomed.

If Microsoft and its hardware partners can get the size, weight and design details right, I suspect I would rather have a Windows 8 tablet than an iPad. One advantage is the ability to have two apps side by side. Microsoft’s new user interface works really well with touch. I will expect to find a Windows remote desktop client there by default, and better support for Microsoft Office and SharePoint than I find in the iPad.

By the time Windows 8 comes out though, we will likely have iPad 3 with who-knows-what improvements; Apple has all the apps; and breaking into this market will not be easy.

Why I miss pinball machines

I’m just back from Microsoft’s BUILD conference in Anaheim, California, where I had little time to do much other than attend sessions, write, eat and sleep (a little).

I did have a quick look round the exhibition though, and was pleased to find four pinball machines. Unfortunately I never got a go, except on one that proved to be slightly broken. Another was so broken that it was switched off.

image

That’s one of the reasons you don’t see many pinball machines these days. They are high-maintenance, with many moving parts that get pounded constantly by one or more heavy silver balls, plus the occasional thump from the player as he bangs or shifts the machine just enough to affect the ball’s motion without causing, he hopes, a tilt.

Another reason for the game’s decline is that a good player can play for ages on a single quarter – or 50c, which seems to be the going rate now. It is a game of skill where accurate shooting gets you both long games and frequent extra balls and replays.

Neither of these characteristics is good for arcades, which like high income and low maintenance.

I love the game though. It offers tactile, physical pleasure that will never be captured by video simulations. The machines themselves are pure delight, every one different, often with gorgeous artwork and amazing gameplay with loops and tunnels and mini-play areas and fantastic contraptions that enable themselves if you get the right sequence of targets.

Most latter-day machines have a multi-ball mode, which is a lot of fun and surprisingly difficult. Watching several balls at once is a great deal harder than keeping your eye on just one.

I am not sure that pinball machines are made any more, though enthusiasts seem to be able to keep the old ones going. Sadly a lot of the machines you encounter in dusty corners of cafés and arcades are not in good order, the bumpers do not bump as they should, some features do not quite work, and they are disappointing.

The best one at BUILD was called Pirates of the Caribbean and seemed pretty good, though I never got a game.

Most of the time I have to make do with computer simulations. The best I have come across are the Pro Pinball series for the PC (don’t get the Xbox version which is a poor port). I was on a forum once with one of the developers, who explained how he hated scrolling on pinball simulations. I agree – how you can shoot accurately with the play area is scrolling all time? There is also an amazing open source project which lets you load actual machine ROMs for authentic simulation, though this is of uncertain legality.

I am more interested in simulations than pinball-ish games that you could never build. One of the great features of Pro Pinball is that you can go into a maintenance mode and tune it as you would a real machine.

Unfortunately none of these are anything like as much fun as the real thing, though they do save on quarters or your local equivalent.
