I want to find all occurrences of a specific phrase in a set of audio files (it's a catch-phrase in a TV show). The phrase is pronounced by different people with different speed etc. What is the best approach to this problem?
Additional details: It's a one time thing. The end result should be a program that takes 30 hours of audio and produces timestamps of a particular short phrase. Obviously the training will be required. Problem is that while I'm a seasoned programmer I have pretty much no experience with speech recognition. I know that phoneme recognition engines exist will they get the job done? For now I need some pointers in the right direction.
