Codebook Design Considerations for Low Bit-rate Speech Coding Using Joint Segmentation-quantization
This paper considers the design of codebooks for low bit-rate speech coders which apply joint segmentation-quantization. Two issues are addressed. The first is the design of a codebook from training data when the data vectors vary in size, as dictated by the segmentation process. For this task a modification of the Generalized Lloyd Algorithm (GLA) is devised. The second issue is assigning indi...
متن کاملLow bit-rate speech coding using quantization of variable length segments
This paper describes a new segmentation and quantization technique for low bit-rate speech coders. Bit-rate reduction is achieved by combining segmentation and quantization, where a segment consists of one or more adjacent frames. The algorithm for selecting and quantizing segments from a pre-determined number of frames extends the frame-based trellis techniques. It models the input speech as a...
متن کاملUltra low bit-rate speech coding based on unit-selection with joint spectral-residual quantization: no transmission of any residual information
A recent trend in ultra low bit-rate speech coding is based on segment quantization by unit-selection principle using large continuous codebooks as a unit database. We show that use of such large unit databases allows speech to be reconstructed at the decoder by using the best unit’s residual itself (in the unit database), thereby obviating the need to transmit any side information about the re...
متن کاملSpeech spectrum representation and coding using multigrams with distance
The multigrams allow us to split a string of symbols into a stream of variable length sequences. The direct application of this method to vector-quantized speech spectra fails, we develop an extension of the method called modiied multi-grams or multigrams with distance. The algorithm for mod-iied multigram dictionary training as well as experimental results are presented. We found a signiicant ...
متن کاملUsing FFI Interpolator and VQ Quantization for Designing of High Quality 1200 BPS Speech Vocoder
Storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. We used stochastic inter-frame interpolators and vector quantization (VQ) as a new method for developing a high quality 1200 BPS speech vocoder. The objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 BPS standard vocoders (as CELP).
