I am doing a project on speech recognition using the microcontroller which then has to open or close the door.
but the problem that i am facing is that i am pretty new in this field.
so here is what my speech recognition ckt has to do
1. maintain a database of 2 or 3 person sound of two command OPEN and CLOSE.
2. when the authorized person speaks on the mic saying OPEN or CLOSE has to turn on the DC motor.
3. if an unauthorized person speaks to the mic then generate a buzz sound.
when these task were performed by the microcontroller then it has to dirive a DC motor in order to open or close the door. for this purpose i have thought to use the H-bridge.
and also i got this site which contains and 8051 like microcontroller that works with in-built speech recognition technique. so i hope that this might work.
