speech recognition project

[wadheraswati]

I am making a speech recognition project using atmel32.
here is the circuit diagram.. I want to interface the LCD with it and print the no.s by speaking. Please help me with the interfacing. After completion of this, i will proceed to construct calculator...

Assuming AtMega32, 8bit micro's are not enough to process speech signals. Better go for higher devices

Yes the said microcontroller might not be sufficient to speech recognition.

Here some example to interfacing LCD with it

i was about to use HM2007 earlier, but then due to unavailability of this IC, i searched so much on net and got this circuit.

Yes but I have seen some recognition system of this IC

You can try-out your circuit. Here some example Voice Recognition Robotic Car

In bangalore we get this IC, but costs 4500rs.

i got 2 and made 5 different projects. very good.

but making its circuit drained all my experience. Finally had to get the circuit from the vendor in US

 

[wadheraswati]

Now i am thinking to buy it from sunrom technologies. But it has LCD interfacing with it on the kit itself. What more can i add to the kit so that i get to present my project as much as technically sound. I am thinking of making a calculator.. Please help me with it.


After viewing the image. Please tell me that will i b able to connect something new or should i take out the IC from the kit and make my own.

The module has facility to connect with other MCUs check the datasheet

It depends on you, If you have time then you can try to build a circuit and consider about the cost also

Now i am thinking to buy it from sunrom technologies.

See if they guarantee its working, as 4 of my friends bought it from sunrom but only 1 worked properly, it had power supply reset and all other issues, where he did not exchange them, we spent lot of time debugging it looking into the master board i got from "HM" USA.
There are some flaws in the design which works sometimes.
Since they are very costly, request you to get it from source who will test it in front of you before delivering. In bangalore also it is available.

If you are planning to buy one, better go for HM2007 module. I tried working with HM 2007 as well as tried to build another circuit for speech recognition with an 8 bit Atmega128 processor. It worked fine.
