The newest TWELP vocoder operates now also at extremely low 300 bps bit rate, providing an acceptable speech quality (higher than 2.0 PESQ), an intelligibility of speech and even a recognizability of the speaker voice.
The 300 bps vocoder opens inaccessible earlier new possibilities of telecommunication at long distances and in hard conditions at HF as well as in other fields, where a very high compression of speech is required.
TWELP 300 bps Vocoder is available now as an object library for any DSP, RISC and other platforms.

The newest TWELP vocoder provides a more natural and a much more intelligible sounding of speech by setting new a standard of speech quality at such a low bit rate as 600 bps.
A superiority of TWELP 600 bps over MELPe 600 bps is so high that it exceeds the competitor on average on 0.13 PESQ and even on more than 0.2 PESQ for some languages.
TWELP 600 bps Vocoder is available now as an object library for any DSP, RISC and other platforms.

TWELP vocoder provides a natural high-quality sounding of speech as well as any non-speech signals even at such a low bit rate as 1200 bps. We improved the speech quality of TWELP 1200 bps vocoder more, significantly increasing a superiority over any competitors. Now, an advantage in speech quality over the nearest competitor (MELPe) exceeds on average 0.1 PESQ!
The updated TWELP 1200 bps vocoder available now as an object library for any DSP, RISC and other platforms.
