How to compare audio files?
in [Matlab]
|
From: Amir on 8 Jul 2010 16:30 I'd like to compare audio files (for instance: WAV files), more preciserely I want to find how many times in an audio file appears one other audio file. How can I do this? I'm waiting for your help. Thank you for your time.

What have you done so far? Does the contents of the WAV file appear exactly in the other file or is there a certain noise and changes due to resampling? Jan

That's quite a different problem, as words are pronounced in different ways at different times and different words can be pronounced very nearly the same way. For example, try automatedly recognizing "Mary is merry".

Again: Then the shorter sound is *exactly* cut out from the larger one? If is is only the "same word" is a hard task. It is time to explain your problem with some details. Jan
