My new idea for super low bandwidth communication

(1/1)

Circlotron:
Make this has been done before, I don’t know. How about sending to a remote station an AI model of your voice. Then, at the transmitting side, simply turn your voice into text and send the text characters. They have the words reconstructed at the far end into something that sounds the same as your voice again.

Kleinstein:
Ai voice is not very easy to understand it would lack the additional information in emphesis and such. It would be usually easier to directly read a text, especially if there are transmission errors.

just add a text to voice on the receiving end if Ai voice floats your boat.

mawyatt:
For the actual comm link consider BPSK, it's the most efficient modulation scheme known wrt noise immunity and why it was used with the Voyager Space Crafts.

ataradov:
If you care about voice reproduction to the extent of transmitting minor variations, then this is not going to work at all.

Otherwise, the idea of using unique voice characteristics and using them for compression is not new. This is basically what Linear Predictive Coding (LPC) does on a low level. If you have a specific speaker in mind, you can create and pre-train a better predictive model. It will not be as efficient as plain text, but it will transfer actual voice.
