Does any one know where one can obtain specifications on the different formats of the digitized data that the Voice Power board creates? Having this information I could foresee creating software to manipulate and even create various sounds, music, speach, etc. How 'bout voice recognization software! Any info would be greatly appreciated. --- Bill Nesbitt ..uunet!miavax.ir.miami.edu!nez!nez

Unfortunately AT&T decided to keep the information on the *format* for digital data storage for the Voice Power board, proprietary. The information on the DSP that is on the VP board is also proprietary, although the new models (DSP32 family) aren't. The internals about on-the-board compression are hidden away as trade secrets within AT&T, probably never to be released. Things like text-to-speech (and how to create your own tts libraries), silence compression, and speech recognition were never fully supported on the UNIX pc (although this might be different with the 6386WGS VP product). The VP Reference Manual states that those components of Voice Power are for "evaluation" purposes only. |>Having this information I could foresee creating software to manipulate |>and even create various sounds, music, speach, etc. How 'bout voice |>recognization software! |> The VP board can do rudimentary voice recognition. I have a small program that will recognize "yes, no, one, two, three, and four" but that's it. I have *no* idea on how to add to the recognition models to add new words, and of course no one at AT&T has been of any great help in that department. -Lenny -- | Lenny Tropiano ICUS Software Systems [w] +1 (516) 589-7930 | | lenny@icus.islp.ny.us Telex; 154232428 ICUS [h] +1 (516) 968-8576 | | {ames,pacbell,decuac,hombre,sbcs,attctc}!icus!lenny attmail!icus!lenny | +------- ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752 -------+

Just a side note, I forgot to mention a good reference on the "Speech Processing Technology". AT&T Technical Journal "Speech Processing Technology" September/October 1986, Volume 65, Issue 5 Order back issues from : AT&T Customer Information Center (CIC), PO Box 19901 Indianapolis, IN 46219 or by calling (800) 432-6600. I believe they are ~$8.50 for back issues. Note the journal is very technical, although some of the information may be outdated, a lot of the technology is still the same. The entire issue is dedicated to speech technology, and one article "Speech Processing for AT&T Workstations" speaks about the Voice Power Product on the UNIX PC (pictures and all) Again the information on the DSP20 (the digital sound processor on the VP board) is proprietary, although they have an article on the newer version the DSP32. Standard Disclaimer applies (I have no affiliation with AT&T, AT&T Technical Journal, or Voice Power for that matter ...) -Lenny -- | Lenny Tropiano ICUS Software Systems [w] +1 (516) 589-7930 | | lenny@icus.islp.ny.us Telex; 154232428 ICUS [h] +1 (516) 968-8576 | | {ames,pacbell,decuac,hombre,sbcs,attctc}!icus!lenny attmail!icus!lenny | +------- ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752 -------+
