The phase-only version of the LPC residual in speech coding
نویسندگان
چکیده
Recent work has demonstrated the perceptual importance of the long-time phase of speech. In this paper, the possibility of using the long-time phase of the LPC residual signal in speech synthesis is investigated. The perceptual importance of the various parts of the long-time spectrum of the residual is also suggested.

An Improved Method of Speech Compression Using Warped Lpc and Mlt-spiht Algorithm
Frequency –warped signal processing techniques are attractive to many wideband speech and audio applications since they have a clear connection to the frequency resolution of human hearing. A warped version of the linear predictive coding (LPC) for speech compression is implemented in this paper and an analysis of the application of Set Partitioning In Hierarchical Trees (SPIHT) algorithm to th...
متن کاملLow - Delay Wideband Speech Coding Using a New Frequency Domain Approach
In this paper a new frequency domain approach suitable for low-delay wideband speech coding is proposed. Working in the context of residual speech coders, the proposed technique performs a decomposihon of the D I T of the target vector, (the input speech after the subtraction of the zero input response signal), as the product of the DFT of the impulse response of the LPC synthesis filter and a ...
متن کاملRELP Coding for Voice Communication
In mobile communication systems, bandwidth is a precious commodity, and service providers are continuously faced with the challenge of accommodating more users within a limited allocated bandwidth. Linear Predictive Coding (LPC) offers low bit-rate speech coding that can be used to meet this challenge. The lower the bit rate at which the coder can deliver toll quality speech, the more speech ch...
متن کاملResidual-based speech modification algorithms for text-to-speech synthesis
This paper presents a set of novel algorithms for the signal modification component of concatenative text-to-speech systems. The algorithms described here are based around the LPC analysis/synthesis framework, and achieve prosodic modification by time-domain processing of the LPC residual. The modified residual is then recombined with the all-pole spectral estimate to synthesise the new speech ...

The Harmonic Excitation Linear Predictive Speech Coder (HE-LPC) is a technique derived from MBE [1] and MBLPC [2] type of speech coding algorithms. The HE-LPC coder has the potential of producing high quality speech at 4.8 kb/s and below. This coder employs a new pitch estimation and voicing technique. In addition, new DCT based LPC and residual amplitude quantization techniques have been devel...
