Voice recognition in C#

[Sadanand]

hi all,
I wanted to implement an application which does record our voice and
recognize the voice,
let me clear the problem statement, say I will talk something and my
application should save
whatever I will talk into a .wav file or any other file format, and
soon after saving it should recognize
the voice from the saved file and should convert it to text form.

If it is bit difficult to explain in detail in forum then please do
provide me some useful link
related to this topic.

Thanks & Regards,
Sadanand

You could try:

 

IBM viaVoice

or

Nuance Speech Recognition System

 

I worked with both, its easy an simple if you buy the SDK.

I have no idea if there is a free speech recognition engine on the market.

 

with both systems above, you can easily "convert" speech to text, dependent from the used language.

Both systems comes with a recorder and a recognition unit. Easy to implement and use. Both have also sample code in C#.

 

 

If you want to develope such an engine by your self, have a happy time :) :) :)

Is it possible to save whatever I talk in a .wav file using TTS? why I
am asking is because TTS
does convert Text to Speech, but what I want is first save the speech
in a .wav file then use the
same file to recognize the speech.

For Vista or newer OS use .NET's System.Speech namespace.
For XP or older OS use the COM component "Microsoft Speech Object
Library" located at C:\Program Files\Common Files\Microsoft Shared
\Speech\sapi.dll.
