Speech quality of the updated TWELP 600 bps vocoder close to quality of well-known vocoders
on twice higher bit rate 1200 bps, providing more natural and more intelligible sounding of speech.
Superiority of the updated TWELP 600 bps vocoder over MELPe 600 bps vocoder is giant- exceeds competitor in average more than on 0.2 PESQ and even almost on 0.3 PESQ for some languages.
TWELP 600 bps Vocoder is available right now as an object library for any DSP, RISC and other platforms.
