Vocoder_NARA_Project.rar - This is a project of LPC vocoder in matlab.
El objetivo de este proyecto es implementar una codificació n de la señ al de voz medi ante un vocoder LPC y realizar ademá s el proceso inverso, recuperando la señ al sinte tizada.
Los Vocoders (“voice coder”) tienen como objetivo preservar las caracterí sticas percep tualmente relevantes de la señ al de voz. Para ello asumen un modelo simplificado d
e producció n de voz.
Se basan en modelos especí ficos de la señ al de voz, identificando aspectos relevante
s del espectro localizado de la señ al de voz, es decir, explotan la baja sensibilidad del oí do a la informació n de fase.

MATLAB Implementation of LPC algorithm for speech signal
# Why LPC?
In communication systems it is often necessary to transmit audio(speech) signal in compressed or encoded form because of bandwidth limitation of the channel. In this regard, ‘Linear predictive coding(LPC)’ is an effctive method of speech coding at a low bit-rate.
# Features
** Analysis/Encoding phase,Synthesis/Decoding phase.
**Human voice modelled with all-pole filter.
** LPC parameters(filter coefficients, pitch, gain etc) extraction at the decoding phase.
** Non-overlapping frames of 30 milliseconds in duration
# How To Run
** Make sure MATLAB(latest version) is installed
** Put both files(LPC.m with .mp3 file) in the same folder
** Open LPC.m file and run it.
## Comments
Different audio (.mp3) files can be coded/decoded by changing the input file name in the code.,2015-11-15 04:22:38,下载6次
