scilab program to speech signal information
This program is used to get speech or voice signal informations such as sampling rate, bit deoth and tine duration of speech signal etc
//Caption: Reading a Speech Signal &
//[1]. Displaying its sampling rate
//[2]. Number of bits used per speech sample
//[3]. Total Time duration of the speech signal in seconds
clear;
clc;
[y,Fs,bits]=wavread("E:\4.wav");
a = gca();
plot2d(y);
a.x_location = 'origin';
title('Speech signal with Sampling Rate = 8 KHz, No. of Samples = 8360')
disp(Fs,'Sampling Rate in Hz Fs = ');
disp(bits,'Number of bits used per speech sample b =');
N = length(y);
T = N/Fs;
disp(N,'Total Number of Samples N =')
disp(T,'Duration of speech signal in seconds T=')
//Result
//Sampling Rate in Hz Fs =
// 8000.
//Number of bits used per speech sample b =
// 16.
//Total Number of Samples N =
// 8360.
//Duration of speech signal in seconds T=
// 1.045
