IMPORTANT: As with most properties of speech, the criteria described below are only going to be useful in relative terms--your script is going to do much better the more specifically it can be trained (either automatically or by you feeding it the appropriate parameters as arguments) for a specific individual in combination with a specific recording setup, ...

As you know from your previous questions on the topic, the waveform of a breathy voiced vowel is more sinusoidal in shape compared to that of a modal voiced vowel, which is more triangular. The power spectrum of the two types of vowels differ in that more of the energy is distributed over low frequencies in breathy vowels, compared to modal vowels. As I ...

But whatever methods it draws on, the grading formula isn’t a theory; it’s a ...

I don't think you've given enough detail about what you want to do with 'some statistical analysis', but I'll take a stab. I am not a stats expert, so these rough ideas will need to be checked by someone who is; I present them for you to know what to ask about. If you want to be able to say 'it's 85% likely that this person is from the longer VOT group', ...

Chrome/Chromium uses the open-source Compact Language Detector. You could use it too. It does not work perfectly, as it is mainly designed to be compact (small, and fully local - no calls to the network), but Google and Chrome are behind it, and it is improving.
