Answer 1

What is a wave file converted to text? What do you expect the text to look like? What 'languageid' are you referring to?

Hi Munish,

I think you maybe thinking of what is known as SPEECH RECOGNITION software so that when somebody says a word like "one" then the letters that spell the word are inserted into a TextBox or similar.

SJ is correct - you do not want to convert the wav file to a text file - that would be meaningless.

What you want to do is read or modify a specific portion of a wav file header - and that you can certainly do.  But you're going to have to know all about the wav format encoding so that you can decode it and change the appropriate values.

I think you'll want to start here:  http://www.sonicspot.com/guide/wavefiles.html

You'll want to start by reading the entire wav file into a byte array (System.IO.File.ReadAllBytes).  Then you will begin to read appropriate header values to determine where the chunk you want is located within the array.

I think you're looking for the "Labeled Text Chunk".  You'll need to follow the specification to find this chunk within a given file, and then use the offset in the chart to write the appropriate 2-byte value back to the byte array.

Once finished you can use File.WriteAllBytes to replace the original file with your modifications.
