Speech Recognisation in Qt

Ravinder

Hi All,

I want to use speech to text in my qt application. I did a lot of workaround and try to use SAPI ,nuance etc. but did't got any usefull result. Now i am getting a project demo named *VoiceToGoog* _here http://code.google.com/p/voicetogoog/_  but in this source is not available :( . Anyone have any idea how to achive speech to text in Qt . Thnx in advance

Qt has no speech recognition APIs, your best chance is to look for a third party library, preferably a C or C++ one, since it is a performance critical task, and use that alongside Qt.

@utcenter....thnx for your reply mate...have u any idea which third party library i can use and how because i tried to use phonesphinx and nauance ..but didnt find any success :(.

What the problem with Windows SAPI? or you need speech recognition for over platforms? There is good examples in Windows SDK for programming with SAPI.

@AcerExtensa , thnx for rply ...can you provide me any link or url regarding this.... i want to use this for my Qt Symbian. I had read much about PocketSphinx also, but not able to port that for my Qt.

AcerExtensa

Windows SAPI is only for windows and windows ce, you can't use them for Symbian. Anyway, you can find SAPi samples here: http://msdn.microsoft.com/en-us/library/ee125103(v=vs.85).aspx

@AcerExtensa ...i want to use that for my Qt Symbian...have u any other idea that how can i achieve this task. I read a lot about HTK, PocketSphinx etc. but these are not promising.

AcerExtensa

Have no idea about Symbian, but where is some simple GPL'd projects, maybe you can use some of them. For example "Open Mind":http://freespeech.sourceforge.net/

It will be sweet sunny day, when I will contribute Qt. I will work on QtInteractive module (face recog, speech recog).

But now it's only idea.

@tucnak ...thnx for that...but i need it now...have u any idea how it can performed.

We in Digia are working with Nuance to get this plug in working well in Qt. We have a demo that is using speech recognition. If you are interested in this, please contact us, and we can see what we can do to help you :) contact me directly, or send an e-mail to qt.info@digia.com
