English ain't English

Your first interaction with Dragon is setting up your user account and voice profile. One of the choices you make is which base language to use for your voice profile. This post helps you choose the right setting for you.

English is the first language of around 375 million people. Up to another billion people, depending on how you define mastery of the language, speak English as a second language. The countries with the largest populations of native English speakers are, in order, the USA, UK, Canada, Australia, Ireland, South Africa and New Zealand.

All of us speak the English lingua franca differently, of course. Not only do we have accents that makes some words sound different from region to region, we also use different vocabularies that include unique words and phrases. Other software can readily be used across the English-speaking world with minor spelling changes. Getting the best speech recognition accuracy requires a bit more work.

To achieve high initial accuracy, Dragon asks you to nominate a language when you use the New User Wizard. This is a starting point for Dragon to learn how you speak and, if your speech is a good match for one of the languages, making the appropriate choice gives recognition a significant boost. The language model includes an accoustic model (how words are pronounced) which is based on data sets of people speaking from those countries.

There's also a language model based on text collected from such sources as newspapers and web pages. The language model contains not only a list of words -- a vocabulary -- but also frequency information about phrases of two, three and four words. Dragon takes your speech, filters out ums and ahs, then puts the acoustic and language models together to recognize your speech.

When you run the New User Wizard, you can choose from the following settings:

  • US English
  • UK English
  • Australian English
  • Indian English
  • South East Asian English

When you choose the US language, you can also specify an accent (General, Australian, British, Indian, Inland Northern US, South East Asian, Sourthern and Spanish). This gives you an acoustic model that should be a better match for your accent but retains a US language model so that you Dragon uses US spelling and vocabulary.

Canadians can safely class themselves as US English for the purposes of Dragon and UK covers Irish accents as well as the diversity of speech found throughout the United Kingdom. South East Asian English covers Singaporean and Malaysian English, and is helpful for Hong Kong speakers. While many New Zealanders get good value enrolling as Australians, more revile at being categorized with their Antipodean neighbours and use the UK language model.

If you don't come from one of the broad categories above, choose the closest model to your accent -- often UK English -- to set up your voice profile. The language model is just a starting point and if you correct recognition errors as you use Dragon, your accuracy should improve.

If you speak English as a second language, check to see whether there's a Dragon version for your native language. That version may include English as well.

It is fine for Canadians to use the US English in terms of recognizing accents but what I find frustrating is that the spelling of words in Canada is traditionally closer to the English of England than to the US.  It gets tiresome constantly changing words like center to centre.  Using the UK English dictionary has other words that we traditionally spell more like they are spelled in the US.  I have tried changing the words in the dictionary, but it seems that some words just cannot be changed.

Over the past 15 years, we've trained many non-native speaking English users. The key to high accuracy is not necessarily your native language but that you enunciate words clearly and speaking phrases. On our website, we have three sound files on how to sound and how not to sound. Listen to these at:

I know that English is not English ... when I bought Dragon the plan was to use it with a tutee who is bornin Canada, with English as a first language. His speech pattern, while it is a little unclear at times, is simply unique primarily. No amount of training has helped. Dragon does not recognize him. An unexpected, but welcomed benefit is my positive experience with Dragon. Are there things that I should be doing differently with my tutee?

that is a funny (and important) topic to some of us.

I think Germans are told that when they use English, they should choose the Australian version.

I used to live in England, and then started working with Americans for years. Eventually I switched language profiles. Accent-wise, I am "foreign mid-Atlantic". I have some issues with accuracy, and it improves if I try to speak more American.

Hi Hans,

Re> I think Germans are told that when they use English, they should choose the Australian version.

I haven't heard that advice before but, as an Australian, it's nice to think that Germany and Australia share English pronunciation!

I'll confirm with my German colleagues but the best model would be either UK or US English, depending on which accent is the best match for yours. Then do additional training for increased accuracy.

Caveat: If you learnt English as a backpacker on Bondi Beach, Australian English would be the best bet!

Hi Ken,

Re> His speech pattern, while it is a little unclear at times, is simply unique primarily.

This hard for Dragon which, as you know, relies on a statistical model of how people "generally" speak to recognize syllables and words. People who are statistical outliers, for whatever reason, can have trouble getting accurate recognition.

Best advice in this situation comes from Marty above where the focus shifts to the speaker's enunciation and how that may be improved.

Mel,

Re> Canadian English...

I'll pass on your comments to our product team. I know we handle at least some Canadian requirements such as formatting of postal codes but seems more work is required.

Best regards,

Derek

I am a fairly new Dragon 10 preferred user and despite having an Australian accent it works well with only a few problems when dictating text. I guess my biggest problem is that for work I need to use it to operate EXCEL and I find great difficulty in getting it to recognise movement instructions. The word that gives me the most trouble is "cell" which about half the time is recognised as "sell". This can make working very slow.....I tried training the word, training commands, deleting "sell" out of the dictionary but needless to say either it has not helped or - in the last case - corrupted the installation and crashed the product so I had to re-install it.

Has anyone any hints on how to improve voice recognition for something like EXCEL?

So you're seeing the recognized phrase including "sell" inserted into the current cell? Just check that the commands are correct in the Command Browser. The majority of the Excel commands don't have "cell" in them so I'm wondering whether you are using a navigation command that sounds logical but isn't valid?

I just tried a few Excel commands here with my admittedly light Oz accent in v10.1 and they work fine.

If that doesn't work, you can try turning on Command Mode which restricts recognition to commands only. If you are able, hold down the Control key when you dictate a command containing "cell". (See Help for other ways to turn Command Mode on.)

If you're still not getting a good result, please contact tech support. via the Australian contact number for further assistance. See australia.nuance.com/support for contact information.

Best regards,

Derek

Actually, in MS Excel the word "cell" is used in such commands as "go to cell a1", or simply "cell a1", or "select cell a1 to cell b3", and so on. You can also use "move right one cell", "move down two cells", e.g.

The problem with recognition, however, usually occurs when you pause just a little too long between "cell" and the following letter/digit, but also if the specific letter isn't recognized as easy, which may happen very often. Then, Dragon will hear the word, but interpret it as "sell", "so", or whatever, because that's what it sounds like also, and deleting these words really isn't the way to go.

One way to make it easier for Dragon to understand what you want to do is using the so-called military alphabet here, in order to dictate the name of the cell you want to navigate to. So, using "(go to) cell charlie five" usually works better than "cell c5".

Nevertheless, although dictating into Excel really isn't as easy doing so with MS Word, for instance, and it takes a little practice, you will get there however if you try just hard enough.

Good luck

What about French? Do you have plans for other languages other than English ain't English? Thanks. Marie-Armande.
