Hi Patrick and group, I wonder if there would be much interest in this kind of DV? The main argument was for having a high quality sounding voice in real time.
In the early 1980's, there used to be a product called HERO (Heath Educational Robot) which allowed simple phoneme entry so that it could "speak." Of course it did a lot more with a robot arm and was ambulatory and had various sensors and sonar ranging, etc. I built one of these kits for a shared robot experience with our school districts and used to demonstrate it to teachers. The programming could be entered manually via a keypad. The voice quality not always easy to understand, and it was definitely what we call robotic:) If the phoneme quality was improved with a clearer sound that I am sure can be done with today's technology, I can see where a phoneme based system could theoretically work. I am not sure if it would receive wide adoption, but if it was the only way to effect weak signal voice, maybe it could have a niche area of interest? I wonder what other group members think about that? 73, Rick, KV9U Patrick Lindecker wrote: >Hello Rick, > > > >The only solution to do voice exchange with a low S/N would be to translate >all the pronounced words in symbols (through some program able to "understand" >voice, the symbols being phonemes or words), to code these symbols through a >Varicode with, for example 40.000 different symbols, to transmit these symbols >and to reverse the process at reception: decoding of the symbols and >pronunciation through an auxiliary program handling an artificial voice. >The transmission mode would be some MFSK16 or Contestia mode (rapid and >reliable). > >I have listened some test in spanish with artificial voice reading words.
