Talk:Linear predictive coding

From Wikipedia, the free encyclopedia

Could someone please add equivalence to the Kelly-Lochbaum vocal tract model? At least on the history section. I'll do it in a while if I have the time.... Oyd11 23:02, 18 June 2006 (UTC)

I wanted to ask if it makes sense in your opinion, to add an article "lossless tube model" and to link it to the first sentence of the "Motivation" subsection. I think such an article would be useful, since Rabiner and Schafer use in their book "Digital Processing of Speech Signals" about 16 pages to cover the theory of a lossless tube model. --Bjoern.thalheim 12:36, 5 August 2006 (UTC)

[edit] Perceptual Linear Prediction

PLP mentions "Perceptual Linear Prediction", but those words are currently unlinked. Should it link here? (is "linear predictive coding" the same as "perceptual linear prediction" ?) --68.0.120.35 17:15, 28 January 2007 (UTC)

Perceptual Linear Prediction should probably have its own page which references this one - while it's based on the same idea as LPC (i.e. fitting an all-pole model to a short-time digital speech signal), the algorithm is different from the standard ones used in basic LPC analysis.

[edit] Use in computers

The Speech Synthesizer for the Texas Instruments 99-4 and 99-4/A Home Computer was able to use LPC for generating natural sounding speech. Notable uses of it were the games "Parsec" and "Moon Mine".

The IBM PCjr used the same Texas Instruments speech synthesizer chip in its optional speech sidecar as TI used for the Home Computer's speech option, though IBM's implementation was not as versatile and very few PCjr programs made use of it. (The PCjr also used the same TI Complex Sound Generator chip as TI's computers, as did the Radio Shack Tandy 1000 computer series.)

Other computers and game consoles like the Magnavox Odyssey^2 and Mattel Intellivision used pre-digitized audio for speech, or played back recorded audio from a cassette tape.
