Vojtech,
Thank you for reading my papers. I have no intention of re-inventing the
wheel. The project is like echolink and does not understand speech or change
to text. Books that have been done in the past did not have narrow bandwidth
as their main objective. I do not need hi-fidelity to

Look at the LPC-10 codec. You could try it by downloading internet
telephony software from speakfreely.org. The codec was developed with
the low bandwidth in mind and its intelligibility is on the

In my opinion time delay is not even necessary, it is a matter of
choosing the right compression at the right level.
If I had time I would start the following project:
* choose an existing speech-to-text converter (open source)
* use cbh compression on the text, as normally no more than 250
Hi Mike.
I studied some aspects of voice recognition about 10 years ago when I thought
of joining a research group at Czech Technical University in Prague. I have a
260 pages text book on my book shelf on voice recognition.
Voice signal has high redundancy if compared to a text transcription.
Leigh,
I hope to have the project used throughout the world in less then a
year, once I get started. My problem is that I need someone to help me
start. If I don't find someone, the project will die with my two papers.

I would be plased to have a complete list of the phonemes and corresponding
audio files from different speakers. I fear 44 phonemes will not be enough
to do a context-free analisis.
The data rate will be closer to 200pbs i think, since you will have to
transfer a magnitude component along with

Very low bitrate algorithms exist now. There are a few that operate from
200 bps to 600 bps. The Navy has software called IVOX that gets in this
range.
Can you somehow lay hands on such a 200 to 600 bps codec?
Im VERY intrested.
The IVOX thing is based on 2400 bps lpc. With silence

Hi Patrick,
At each 1/T it was necessary
One thing to try might be an encoding that takes more time to send than
the audio it encodes. If blank space compression is used, the effect
can be reduced. But there is nothing that says the encoding must be
able to transmit voice in 100% of real time to be interesting or
useful.
73,
I did send you a PM.
