Abstract:
Speech Recognition is a technology that can be
useful in many applicationof our daily life. This
proposed method present the speaker dependent speech
recognition system. In this paperinclude the three
steps of speech command recognition systems. Firstly,
automatically crop the input command signal for
removing silent part of the command .The second one
is extract the feature vectors by using Mel frequency
cepstralcoefficients (MFCCs) and then feature
matching the command and predefined speech
command by using Dynamic Time Warping (DTW).
Before matching with DTW, the system sorts the
predefined command for matching with command to
improve performance of recognition. This system uses
the ten predefined command for one username. This
paper also compares the speech recognition system
between the using of Multi-band Spectral Subtraction
and Feature extractions in preprocessing method.
Finally, the proposed system designs the “Information
Retrieval” application using MATLAB.
