Android Voice Recognition (in Search Widget) using given word list

Is it possible to restrict voice search search widget to look for a match near to a given set of words. For example if I am using it to search over a list of names, its not meaningful as names are often corrected to some words.

You could also look at recognition from AT&T. They have a very feature-rich web API, including full grammar support. I only found out about it recently!

1,000,000 transactions per month for free. Generous!

Look for 'AT&T API Program'. Weird name.

Link at time of writing: http://developer.att.com/apis/speech

Unfortunately for me, no Australian accent language models at time of writing. Only US and UK English. Boooo.

EDIT: Some months after I submitted the above, AT&T retired the service mentioned. It seems everyone just wants a 'dumbed down' API where you just call a recognizer, and it returns words. Sure, that is of course the holy grail, but a properly designed, constrained grammar will generally work better. As someone with speech skills, the minimalism of the common Speech APIs today is really frustrating...

If you use 3rd party Android recognition from Nuance (The people behind DragonDictate), it supports a "grammar mode" where you can somewhat restrict the phrases that will be recognised during recognition.

Importantly, if you add unusual names into a Custom Vocabulary, they SHOULD become recognizable (Complex pronunciation issues aside)

You can find information if you dig through: http://dragonmobile.nuancemobiledeveloper.com , looking for 'Custom Vocabularies'. Grammar mode is essentially a special mode of custom vocabularies.

At the time of writing, there was a document here that makes some mention of grammar mode: http://dragonmobile.nuancemobiledeveloper.com/downloads/custom_vocabulary/Guide_to_Custom_Vocabularies_v1.5.pdf - It only really becomes clear when you try to progress in their provisioning web GUI.

You have to set up an account, and jump through other hoops, but there is a free tier. This is the only potential way I have found to constrain a recognition vocabulary. Well, short of running up PocketSphinx, but that is still described as a 'Research' 'PreAlpha'.

No, I don't work for Nuance. Not sure anyone does. They may have all been eaten by zombies. You would guess as much reading their support forums. They never reply.

No, unfortunately this is not possible.
