Hybrid multi-mode/multi-rate CS-ACELP speech coding for adaptive voice over IP

چکیده
This paper presents a hybrid Multi-Mode/Multi-Rate, toll quality CS-ACELP coder developed for Voice over IP applications. The coder uses coding modes compatible with the three 6.4, 8, and 11.8 kbit/s coding schemes standardised by ITU-T in G.729. In particular, the algorithm presents 4 coding categories, with an average bit rate ranging between about 3 and 8 kbit/s, that adapt the rate to changes in network conditions.

SPEECH−ADAPTIVE LAYERED G.729 CODER FOR LOSS CONCEALMENTS OF REAL−TIME VOICE OVER IP (WedAmOR4)
In this paper, we propose a speech−adaptive multi−description coding (MDC) scheme for the loss concealments of CELP−coded speech transmitted in real time over IP networks. Based on the ITU G.729 CS−ACELP codec operating at 8Kbps, we design a loss−robust speech−adaptive codec at the same bit rate. Our scheme employs MDC for concealing losses and adapts to dynamic loss conditions that are charact...
متن کاملAmr to G.729a Speech Transcoding with Fast Codebook Search
Speech transcoding scheme is needed in the voice system over internet. Full decoding technique is an intuitive and traditional speech transcoding method, but it requires high computational complexity and long processing time. In this paper, we propose a partial decoding technique with fast codebook search, which utilizes the pulse replacement method, on ACELP coding architecture. There is no ne...
متن کاملDesign of a Variable Rate Algorithm for the CS-ACELP Coder
In 1995, 8 kb/s CS-ACELP coder of G.729 is standardized by ITU-T SG15 and it has been reported that the speech quality of G.729 is better than or equal to that of 32 kb/s ADPCM (G.726). However G.729 is the fixed rate speech coder, and it does not consider the property of voice activity in mutual conversation. If we use the voice activity, we can reduce the average bit rate in half without any ...
متن کاملThai Speech Coding Based On Conjugate-Structure Algebraic Code Excited Linear Prediction Algorithm
Problem statement: In mobile communication, speech coding aims at compressing the speech with lowest bitrate and highest quality for standard languages such as English, German and French. As for other languages with different uttering styles, the encoded speech quality is not guaranteed at the same bitrate. The appropriate evaluation should be performed to develop the speech quality by applying...
متن کاملA full-rate GSM-AMR candidate
This paper describes a full-rate (FR) candidate speech codec for a new Adaptive Multi-Rate (AMR) codec standard. The proposed codec is a multi-rate codec, operating in various modes that have different bit-rate partitionings between source and channel coding. The source coding is based on Algebraic Code Excited Linear Predictive Coding (ACELP). Convolutional coding is used for the channel codin...
