Re: [AUDITORY] Calculating AI or STI or SII



Stuart,
If you have noise and speech spectra that you do not know upfront, I am not sure how this can be made simpler than typing individual band values for noise and speech?
Chas
P.S.
But there may be an app for this as well.

I am looking for Matlab scripts that make it easy to do calculations for (just about) any kind of measure of speech intelligibility because at the moment I am primarily interested in the effects of the masker spectrum. I am aware of the scripts at http://www.sii.to/ but there is nothing easy about using them in the sense that  you need to enter the levels of the speech and noise in various bands and I don't see why all these calculations cannot be implemented in one easy-to-use package.

Ideally, one would simply call the script with some combination of:

1) the target speech in quiet,  the masker on its own, and an SNR

or

2) the target speech on its own, and the target + masker in whatever SNR was desired.

Any help gratefully received!

Yours - Stuart
