How can analyse sound files for speech recgnition through C?
Answer Hello Speech recognition and voice recognition are the subject of many university research project. The University of Ghent is one that is quite actif on the subject. This is just to say that it is more a question of the algorithm you use than the underlying language. To analyse sound files you need to: 1. Convert the sound file into an internal structure in the C-program (this structure is preferable a linear representation of the sound samples, not an encoded structure such as ALAW or ULAW, MP3 or any other representation). This may require a specific decoding routine if the source file is not adapted (e.g., conversion of mp3 to .wav like format). If memory is limited, the implementation will be somewhat more complex as you need to read the input file on a need basis by the recognition algorithm. 2. Operate the speech recognition algorithm on the samples (contained in an array in the simpliest case for example). This will imply filtering of the samples and voice/speech feature
