In general, voice traffic can tolerate some form of packet loss, depending on the coding algorithm, but a rate of greater than 5% is considered harmful to the voice quality [3] and will result in a drop below toll quality for most coders.Elias Nemer...

From the auto-correlation, the Levinson-Durbin algorithm is used to compute the predictor. Computing the predictor from the cepstrum ensures that no additional information needs to be transmitted (in a speech coding context) or synthesized (in a text-to-speech context). Even though the LPC ...
models are typically used at lower rates. The key attributes of a speech coding algorithm are bit rate, complexity, delay, speech quality, and robustness. Since different applications have significantly different needs and priorities, there is a wide variety of speech coding algorithms currently in ...

From here, we padded the acoustic data by 16 ms to account for the shift introduced by the two filters on the neural data and estimated the boundaries of speech segments using an energy-based voice activity detection algorithm53. Likewise, we computed acoustic features in the LPC coefficient ...
In addition, time and frequency shaped noise models have been used both in the context of speech modelling and in the context of parametric audio coding. However, these applications generally utilise a separate encoding and transmission of time and frequency location of this noise. The technique il...
While the gain factor noise suppression technique is shown for a particular CELP coding algorithm, other CELP or other digital signal processes may be used with time-domain noise attenuation. As mentioned, the unquantized fixed codebook gain and the unquantized long-term predictor gain obtained by...
