Voice Stress Analysis using Linear Predictive Coding in MATLAB
نویسنده
چکیده
Speech in humans is generated by a series of formants generated by the resonances in the nasal, pharyngeal and vocal tracts. Linear prediction of speech is one of the most widely used techniques for analysis of speech samples. Voice stress analysis as a field of study holds immense importance to human life. Stress analysis has been used in critical situation endangering life and in several medical scenarios as well. This paper uses Linear Predictive Coding (LPC) to analyse the stress levels in the voice samples by comparing them to existing samples and outputting a human emotion. Index Terms – LPC, MATLAB, stress analysis, emotion recognition.

RELP 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...

One of the most powerful speech analysis techniques is the method of linear predictive analysis. This method has become the predominant technique for representing speech for low bit rate transmission or storage. The importance of this method lies both in its ability to provide extremely accurate estimates of the speech parameters and in its relative speed of computation. The basic idea behind l...

This paper presents an advanced speaker verification system using wavelet transforms. The conventional signal processing techniques assume the signal to be stationary and are ineffective in recognizing non stationary signals such as voice signals. Voice signals which are more dynamic could be analysed with far better accuracy using wavelet transform. The developed voice verification system is w...
