HI All.

I'm in my first year in EI i need help to do such of matlab software .
:roll:
i want to make such kind of software by matlab, which can recognize baby crying and laughing.
After detecting such kind of high frequencey voice, the matlab software can give result if its crying or laughing .

thank u all :lol:.
 

Hi,
That is quite an advanced problem.

You can start by making two real-time filters for different frequencies (you might have to go through some papers on voices and sound.)
You can design the filters using the toolboxes available in MAT LAB.

Then you have to design a program which continuously takes in audio from the microphone and applies the filter to the incoming data. The filter output can be made to go high as and when the specific frequency range is detected and this can be used to indicate laughter or crying.

Matlab has many simple commands to take in audio and apply filter to them. You would have to go through the help manual quite a bit. Or just ask in forums like these!!
 



nitishn5 thank you for ur replying , and i appreciated that . because i'm new in matlab i think it'll take time to design that program and i'm not good at that.

thank you very much
