Can I have matlab code for speech recognition system for yes

Can I have matlab code for speech recognition system for yes and no detection?

Solution

Speech Recognition:

It is the process of recognising automatically who is speaking on the basis of individual information included in speech waves

Classification:
Speech recognition systems can be classified into several models by describing the types of utterances to be recognized.

These classes shall take into consideration the ability to determine the instance when the speaker starts and finishes the utterance.
Most speech-recognition systems are classified as isolated or continuous. Isolated word recognition requires a brief pause between each spoken word, whereas continuous speech recognition does not.

Speech-recognition systems can be further classified as speaker-dependent or speaker-independent.

A speaker-dependent system only recognizes speech from one particular speaker\'s voice, whereas a speaker-independent system can recognize speech from anybody.

Algorithm:

The speech-detection algorithm is developed by processing the prerecorded speech frame by frame within a simple loop.

For example, this MATLAB code continuously reads 256 sample frames from the data in ‘speech’.

To detect isolated digits, we use a combination of signal energy and zero-crossing counts for each speech frame. Signal energy works well for detecting voiced signals, while zero-crossing counts work well for detecting unvoiced signals. Calculating these matrics is simple using core MATLAB mathematical and logical operators.
