Re: SII Software -- New Web Site (Speech Intelligibility Index)

I suggest that there should be a validation study associated with the new
SII standard.  This could be something like the report published by Kryter
that was associated with ANSI S3.5-1969 (Kryter, KD, 1962, Validation of the
Articulation Index, Journal of the Acoustical Society of America, vol. 34,
no. 11, 1698-1702).
