voice Recogniton from audio file

[mary]

Hi !

I need your help to make an autoit baby cray monitor. I made an audio wav file (as a footprint of my baby cray sound).

by how to compare 2 sound file to do voice Recogniton ?

I think that's very very difficult. I expect that your baby will be asking to borrow your car keys before you get that working.

Moin mary,

I don't know if the following Link will help you, but decide it by yourself ...

Do you think it's th right way to compare two sounds ?

You wrote that you made a Fingerprint of your Baby's crying voice, but what' up if your Baby is croaky or had swallowed something ?

It's a very interesting thing: How to create a Baby Alert System with AutoIt!

If there is more than one baby and you want to figure out which one cried, then I would call this mission nearly impossible.

On the other hand: if you want to distinguish the baby from other sound sources you could start with recording the sound, do a Fast Fourier Transform (FFT) and compare with the FFT of the reference sound. Assuming that the same frequencies are produced every time of course.

I did somthing like this a while ago. I was trying to get my computer to do stuff when I yelled at it and it worked marginally, the trouble mainly came when I was trying to distinguishing the commands. Since you just want to know when your baby is crying It shouldn't be that hard. Especially since not many things sounf like a crying baby. Somthing called a Fourier Transform should help you, just remember to use a large frequencie buffer.
