[Speex-dev] help regarding <voice to text>

[Pintu Agarwal]

Hi Keith,
 
Thanks a lot for your reply.
 
Actually I am trying to build an application in linux & C for converting
a voice file(that is WAV) to a text message.
This is required for one of our voice project.
 
So just wanted to know if there is any existing application already
there in linux to do that.
Otherwise I have to write my own.
 
Now to right my own "wav to text" converter I need to understand how it
works.
Can you tell me the logic behind it?
Do you know any algorithm for it.
 
Plz let me know.
 
 
Thanks, Regards
Pintu

Pintu --

Speex is an audio codec that can encode and decode audio for
transmission over network (or for storage).
Specifically, it's called speex because it is tailored to work well at
encoding speech at small bitrates. 

Speex does not do speech recognition or text to speech.
You may wish to look at CMU's speech page: http://www.speech.cs.cmu.edu/
(look at Sphynx).
And I'll tell you - It is much more difficult (and processor intensive)
to to speech recognition than it is to to speech synthesis (though both
are quite difficult).

	Hi,
	 
	I am need of "voice to text" converter for one of my project. I
need to use it on Linux OS.
	I got "text2wave" converter but didnt find any "wave2text"
equivalent.
	 
	Then I saw "speexenc" and "speexdec" on linux.
	It basically does encoding and decoding the the WAV file.
	 
	Thus I wanted to know if I can use these utilities to convert a
WAV file to a text file.
	 
	Please help!!!!
	 
	 
	Thanks, Regards
