Dear list, I would like to calculate speech intelligibility index (SII) from room impulse responses at a certain signal-to-noise ratio (example for each octave band 5dB from 125 to 8k) according to ANSI S3.5 1997. Does someone have some examples for calculation of SII from room impulse response or have some codes ( Matlab or C ) for it? Many thanks in advance, Yu Xing
