Lots of people ask about this. If we did pure speech-to-text and text-to-speech, it would take about half the bandwidth but everybody would have the same synthesized voice. Once you start trying to add parameters to the synthesized voice such as pitch, speed, and tonality, those take as much bandwidth as we are using for the entire codec, because they are essentially the same parameters.

There are commercial codecs that get to slightly lower data rates, which the government presently uses.

I once had to ask the Pakistani military to not use the mailing list to ask questions, as I didn't want our ham radio project to get in ITAR trouble. Of course they can still use the code, it's Open Source. But they have to get help elsewhere.

That's the theory. The modem also degrades gracefully in a way that lets you use your "ears" to recover information when there are bit errors. No on-off behavior like most digital codecs, in fact one of the samples is rendered with 1% bit errors, which might kill a normal codec or at least require a packet repeat. We have higher bit rate versions of the codec that don't make you work so hard.

I've been programming all day, and haven't said many words at all. There are people who talk for their entire work day, but they generally spend half their time listening and more processing something, so they may actually do 4 hours of speech or less in the work day. Most people don't really speak for more than a few hours per day.
