Speech Recognition using BF532.......

Started by mall...@yahoo.co.in January 22, 2009
Hi!

Iam new to speech recognition..........

We want to do a simple speech recognition (like 4 or 6 words) using BF533EZ kit lite....
I have seen some of the implementations using ATmega32 processor on web,based on them i want to do speech recognition.They used filters(Low pass,High Pass and Bandpass) to filter the finite duration speech and then prepared fingerprints.By comparing the Dictionary fingerprints with Taken samples they are recognizing the samples.They used 8Khz sampling frequency. For each sample they applied 8 to 10 filters and accumulated the outputs,like this they have done for .5 seconds(word size)...........

I think there will be different implementations for ex. in DSP we will take a frame of samples (ex 256) to process rather tan individual samples.....

Is there any other different implementation for doing speech recognition in real time even simple and small project also not a problem....
