I just came across the following message in the comp.speech newsgroup. I think the idea of representing sound spectrograms in a format other than visual (possibly as sound!) might be of double interest to this group.

I'm a grad student studying linguistics at the University of California at Santa Barbara. I am also totally blind. As a linguist, my research interests are leading me to do work on speech prosody and phonetics. Unfortunately, I'm not getting very far because the tools I need for research are inaccessible to me as a blind person using conventional speech or Braille output (Yes, I'm very familiiar with applications for speech synthesis and TTS.) Anyone know anything about acoustic analysis programs, and if/how I, as a blind computer user, can access them? Examples of such programs which we are using in our lab are: CECIL and Speech Science Lab for the IBM, and Mac Speech Lab for the Macintosh. (We also have a program for a Sun, but I'm not sure which one.) Because such displays are highly visual and graphically oriented (frequency traces, etc.), there is no way of using conventional speech or Braille screen access software to read them. Is anyone out there (or does anyone know of) blind computer users who've had success working with such programs who could provide suggestions as to how to make them accessible? Are there any such programs which present spectrographic data in quantitative rather than visual format? I haven't had much luck posting such technical questions to the newsgroups for blind/visually impaired computer users, but I thought someone on this group might have some ideas. If so, please contact me via E-mail. Thanks for any input!
