Thanks to all those who replied to me about the issue of determining speech/music in a soundtrack. I have looked at Slaney's paper, and now have the following problem... Suppose you have some characteristics which you can use to recognise speech (rhythm, harmonics, continuity, energy etc). If there is a piece of the soundtrack which contains a speaker talking, but with music in the background, then the system will recognise it as music. Whilst it is true that it contains music, I want it to recognise the fact that there is speech present, and mark it as speech. Of course it is helpful to me to be able to recognise things with music in, but it would be even better if I could almost re-phrase the problem to be looking out for when speech occurs. Has anyone any ideas on how you might be able to recognise the presence of speech when music is also present. Does it have any special pyscho-acoustic properties, or does the music drown them out? thanks in advance for any comments.
