Dear All,
I need to support about HM 2007 who have to design HM 2007 Speech Recognition Kit for my grudaiton project.
There are the same project in the web but i am not able to work it.
Although The circuit description is exist in this web site , the circuit does not work absolutely.
Therefore ı need to your support -
-Circuit schematic or PCB desing for 8051 or PIC ?
-Is there anyone that do and work it ?
-Can you share your documantaion or design or code or other details please ?

Can you post details of what you have done
even if it does not work.
 akrepkral76 like this.

In the first step i tried to do this project lcd insted of touch panel Lcd but i am not able work it moreover 8051 instead of PIC.
and then the circuit (attehment) have done by me.
But it is still not working 2 times i design but not working.
Can you share your info or decumant or pcb desing with me if you have done this project.

Does the speech recognition board output codes when you talk to it ?

What is you project supposed to do ?

Please post your code.

The project is about speech recognition.
-First there is a microphone (for input data) which the connection is the HM 2007 chip 42 pin.
- Second The circuit has been processing in the speech.
-Lastly the circuit has a two relays in the output side. The speaker says 1 the first relay active ( output on other case output off) Moreover the speaker says 2 other relay active (output on other case output off ).

Also the code and other details here :

That board is self contained, it does not need a micro.
What does your project add ?

Do you have a working HM2007 board as shown in the picture ?

i have used to micro for touch panel because i did not want to desing for key pad. But i am not able to do successfully.
Can you help me adding to touch panel to circuit please ?
How can i use the relay without the micro ?
That board is self contained, it does not need a micro = i overlooked (missed ) the parts i will read more one time carefully.
Do you have a working HM2007 board as shown in the picture ? = i do not understand clearly. Can you explain more clearly ? pls.

On your diagram in your second post is a connector
That is a board like the one from Sunrom.
Do you have that board ?
