Combined harmonic and waveform coding of speech at low bit rates
نویسندگان
چکیده
In this paper we present a new approach for speech coding, which combines frequency-domain harmonic coding for periodic and \noise like" unvoiced segments of speech with a time-domain waveform coder for transition signals. This hybrid coder requires special handling of the boundary between voiced and transition segments. We outline the details of a 4 kbps hybrid coder and present subjective quality test results of this coder.

Very low rate speech coding using temporal decomposition and waveform interpolation
In very low rate coding the aim is to accurately represent speech characteristics as efficiently as possible. High coding gains for the spectral features can be achieved through the use of temporal decomposition. Waveform interpolation coders accurately represent the excitation using characteristic waveforms (CWs) extracted at a constant rate. In this paper, the two approaches are combined into...
متن کاملHybrid harmonic coding of speech at low bit-rates
Activity in research relating to the compression of digital speech signals has increased markedly in recent years due in part to rising consumer demand for products such as digital cellular telephones, personal communications systems, and multimedia systems. The dominant structure for speech codecs at rates above 4 kb/s is Code Excited Linear Prediction (CELP) in which the speech waveform is re...
متن کاملMultiband prototype waveform analysis synthesis for very low bit rate speech coding
Prototype waveform interpolation is one of the most e cient compression techniques for coding the speech signal at bit rates below 4 kb/s. Most of the PWI coders employ prototype waveforms of the linear predictive residual signal for coding purpose. In the latest PWI systems, decomposition methods are used to separate the voiced and unvoiced components of the prototype waveforms prior to coding...
متن کاملLow-bit-rate Speech Coding
Low-bit-rate speech coding, at rates below 4 kb/s, is needed for both communication and voice storage applications. At such low rates, full encoding of the speech waveform is not possible; therefore, low-rate coders rely instead on parametric models to represent only the most perceptually-relevant aspects of speech. While there are a number of different approaches for this modeling, all can be ...
متن کاملA variable rate hybrid coder based on a synchronized harmonic excitation
A novel synchronization technique is proposed for hybrid coders employing harmonic and waveform coding. A new classification technique based on analysis by synthesis to distinguish between stationary and transitional segments is also proposed. Harmonic excitation is synchronized with the LPC residual by transmitting the location of the pitch pulse closest to the frame boundary and a phase value...
