Well, The Articulation Index gives a measure of the intelligibility of hearing speech in a given noise environment. I have some recordings that I used some perceptual coding techniques that caused distortion to these signals. I would like to calculate the AI of the distorced sound. As the AI is calculated based on the environmental noise, I would use the reference sound to measure the 'noise' in the distorted sound.
