codingLSPCS-ACELPThis paper introduces the basic principle of 8kbit/s CS-ACELP speech coding algorithm. The algorithm uses the LSP parameter quantization and the fixd-codebook with the algebraic structure. Moreover, the quantization of gains use the codebook with conjugate structure...
In order to achieve this scalability, the bit ordering in the bit stream is rearranged, and the coding algorithm is partially modified, as described in detail below. [0040] Table 2 shows an example of the bit reordering of the low bit rate coder. The number of total bits in a full ...
The project involves building a system for exchanging voice messages over mail using speech coding, resulting in tremendous speech compression. The sender will record his voice message and transform it into the coded, compressed file using the encoder module. The coded file is transferred as an ema...
ACRcould dynamically adjust the speech coding algorithm used based on the current user environment. For example, the trade-off between speech and error-correction bits could change in response to current radio channel conditions, as in the 4.7 to 12.2 kbps GSM-AMR cellular algorithm, allowing high...
should be done based on an algorithm that locates the “corner” of the L-curve [5], defined as the point of maximum curvature of the L shaped curve obtained by plotting ( x−Xa γ 2 , a γ 2 ) for sev- eral values of γ. This value of γ then offers the best trade-off...

The algorithm transformed the decoded waveforms to be in her personalized voice, which we then used to drive the avatar animation. We synchronized the avatar animation and the personalized decoded voice in this video. Supplementary Video 8 A demonstration of real-time classification of attempted ...

action of the human vocal track (e.g., mouth, tongue, lips). The filter coefficients in the filters 16 and 18 are changed for each block of actual speech signal to be coded in accordance with the adaptive predictive coding algorithm discussed above. When the adaptive predictive coding algorit...
(CELP) algorithm is one of effective coding schemes which maintain a high quality even at a low transmission rate of 8-16 kbps. An algebraic CELP coding scheme, which is one of the CELP coding schemes, is such a successful method as to be adopted in many recent worldwide standards such ...
