Yeh - not sure this will help however - a (very talented) colleague of mine worked on a simple speech recognition software for mobile - it was built to recognise about 20 commands with 90% success rate.
His approach (in my simplistic terms) was: 1) get recordings / audio samples of the commands (in your case vowels - it should be easier as it's generated so you wont have to compare against too many/different intonations ) - 2) create / store a graph of the audio commands ( this used FFT (s) - to abstract and simplify, the pattern of the commands - the result was a square voice print graph ) 3) The stored patterns/voiceprints were then compared against the users voice recording. The trickiest part of this whole business were the Fast Fourier Transforms - these things get very complicated, and confuse the life out of me. Anyway, hopefully this will help you - seems like it might be the best approach. if you do crack it - you will end up with a simple voice recognition system. Which would be a brilliant and useful thing bit of code to have... hope this was of any use.. - karim On 4 Jun 2010, at 01:23, Karl DeSaulniers wrote: > I would try using that to figure out a way of maping the sounds and then > translate that to your project.
