چکیده
This paper introduces a new technique to model the excitation waveform for a linear predictive speech coder. The target application is high quality speech coding for rates near 4 kb/s. Our pitch pulse evolution model decomposes the excitation into two separate but simultaneous signals: the evolving pitch pulse component and the unvoiced, noise-like contribution. A number of formulations for decomposing the excitation waveform are suggested .

متن کاملA Pitch Pulse Evolution Model for Linear Predictive Coding of Speech
Speech coding is important in the effort to make more efficient use of digital telecommunication networks, particularly wireless systems, and to reduce the memory requirements in speech storage systems. The desire for a low-rate digital representation of speech is often contrary to the demand for a high quality speech reconstruction. In this thesis we present a new speech compression technique ...
متن کاملA Predictive Model for the Combustion Process in Dual Fuel Engines at Part Loads Using a Quasi Dimensional Multi Zone Model and Detailed Chemical Kinetics Mechanism
This work is carried out to investigate combustion characteristics of a dual fuel (diesel-gas) engine at part loads, using a quasi-dimensional multi zone combustion model (MZCM) for the combustion of diesel fuel and a single zone model with detailed chemical kinetics for the combustion of natural gas fuel. Chemical kinetic mechanisms consist of 184 reactions with 50 species. This combustion mod...
متن کاملAn Acoustic Study of Emotivity-Prosody Interface in Persian Speech Using the Tilt Model
This paper aims to explore some acoustic properties (i.e. duration and pitch amplitude of speech) associated with three different emotions: anger, sadness and joy against neutrality as a reference point, all being intentionally expressed by six Persian speakers. The primary purpose of this study is to find out if there is any correspondence between the given emotions and prosody patterning in P...
متن کاملSmoothing the Evolution of the Spectral Parameters in Speech Coders
New generation of speech coders have to achieve two goals: efficient use of bandwidth and high speech quality. The objective of this thesis is to improve the modelling of speech signal within the constraints of a low bit rate coder. Many speech coding algorithms use Linear Prediction (LP) coefficients to describe the power spectrum of the speech. These parameters are obtained for blocks of inpu...
