The most relevant piece of software I could find is called Praat. It's free, and it offers spectral, pitch, and formant analysis—but it was developed for the study of phonetics. This is deep software though, and, though I feel comfortable in max, reaktor, and other visual programming environments, Praat is beyond me. It's the most relevant software i've ...

3 options: 1. Izotope RX4 in demo mode, is capable of detecting 'similar sounds'. I haven't used in on voices, but it could work. But you need to consider that it needs clean samples (in the same recording) and that demo will only run for 1 month.. 2. Dragon Dictate is a dictation app that allows discrete dictation in ios and mac osx (maybe also other os'es)....

The direct answer is very generic: Frequency: Changes in wave frequency relate to pitch/intonation Amplitude: Changes in wave amplitude relate to stress and pronunciation But that is pretty much the answer to every other "What are the characteristics of X that make it different from other X'es, in terms of properties of the sound wave?" The more ...

However you do it, you'll probably need a clean sample of the sounds(voices/words) that you want to target, as a spectral reference. The sample could be taken from the recording itself, as long as it was a clean sample(no other sounds involved). This way the sonic characteristics of the recording device would be included. For that reason, the sample would ...

If you pick a well developed "physical modelling" synth such as the following: Then it sounds like you can get what you're looking for. Just don't use a crap implementation but a good one or try to do it yourself if you don't know what you're doing (don't try to replicate years and years of university research). The "choir"...

Are you automating those band pass filters? The filters must move over time to get voice sounds. What software are you using? I achieve vowel like sounds in ableton by taking a synth and running it through two parallel chains, each with single band pass on them. One cut off should be in the low freqs like around 350 hz, and the other in the high freqs ...
