The model overcomes several limitations of traditional glottal models and has potential for application to high quality speech synthesis and low bit rate speech coding.","PeriodicalId":364273,"journal":{"name":"1997 IEEE Workshop on Speech Coding for Telecommunications Proceedings.

The new MB-CELP coder employs a multiband bank of off-line filtered excitation codebooks, fullband linear prediction synthesis, and minimization of the error between original and synthesized audio signals over the full frequency range. Two versions of MB-CELP coder at 16 and 24 kbps are described. Subjective comparison test results show that these coders perform better than G.722 coder at 48 and 56 kbps respectively.","PeriodicalId":364273,"journal":{"name":"1997 IEEE Workshop on Speech Coding for Telecommunications Proceedings.

Varying the temporal location of noise within a pitch cycle corresponds to varying its phase spectrum. Exploiting this fact, we find that a change of phase is more perceptible for a low-pitched sound than for a high-pitched sound. Our results support the notion that sinusoidal coders work well for female speech and that CELP coders work well for male speech.","PeriodicalId":364273,"journal":{"name":"1997 IEEE Workshop on Speech Coding for Telecommunications Proceedings.

In this method, two LSP (line spectrum pair) transformation blocks compute ARMA filter coefficients for the postfilter. The characteristics of the proposed postfilter can be flexibly designed in the frequency domain, because an effect of LSP transformation can be estimated in the frequency domain. As examples of design, an approximation to a conventional LPC-based postfilter, enhancement in selected frequency bands, and a suitable design for a tandem coding are demonstrated.","PeriodicalId":364273,"journal":{"name":"1997 IEEE Workshop on Speech Coding for Telecommunications Proceedings.

A key feature of the coder is a novel line spectral frequencies (LSF) quantization scheme, requiring only 20 bits per frame. With channel coding (using convolutional codes), the new MELP coder at 3.1 kb/s is capable of maintaining good speech quality even in very degraded channels.","PeriodicalId":364273,"journal":{"name":"1997 IEEE Workshop on Speech Coding for Telecommunications Proceedings.
