I can't see a pda audio interface being done right in any O/S other than the palm O/S, CE is out of the question, why should an audio interface have to run through a GUI? Palm/Visor I think they are both Palm O/S based, with 3com Palm we had an "Open software architecture" and with Visor we have an additional "Open hardware architecture" to develop pda peripherals. Software speech synthesis for the Palm is crude, Im not sure if its a limitation of the mc68328 dragonball processor or the simple sound circuitry in the Palm pilot, probably the sound circuit. I have read stories of Soviet software engineers doing amazing things with early Intel processors during the 80's. While the mc68328 is probably a cabable processor for speech synthesis, its the architecture and storage of the palm pilot pda that limit it for good software speech synthesis, speech recognition is probably out of the question. Hardware speech synthesis is probably the best solution for a good sounding audio interface for the Palm pilot. For input a single handed chorded key device would be optimal. Probably cumbersome to learn, but once learned the combination of good speech output, chorded key input and a well designed audio interface will provide an extremly powerful man/machine schemata that would make J.C.R. Licklider proud. A person can be in motion, eyes free not visually captive, palm pilot tucked away with earphone output. I have heard of a scaled down linux kernel running on the the palm pilot but didn't hear anything about performance. A company called Transmeta recently announced support for embedded Linux in its line of low power processors. The unique capabilities of these processors will probably make it possible to create speech recognition/synthesis engines as intregral parts of the physical/virtual processor. Good to see people are interested in this sort of thing, maybe this can lead to the next generation of operating system. I don't know what happened in the last 15 years as far as computer interfaces, but it looks like regression to me. Looks like its gonna take the free software and open source movement to do what the commercial industry has failed to do in the last 15 years.
