Speech Analysis and Synthesis Using Linear Predictive Coefficients

INTRODUCTION

In this project, I will build an LPC Vocoder based on an all-pole model of speech production using MATLAB. This analyzes the speech signal and use the analyzed information to resynthesize the speech signal. The goal of this project is to achieve a compromise between lowest number of LP coefficients and quality of the resynthesized speech.

Also, I will construct a voicing detector and a pitch detector. The voicing detector cuts the signal into frames, and determines if that frame of speech is voiced, unvoiced, or silence. The pitch detector also cuts the signal into frames, and determines the pitch of that frame.
