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 ?

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 ?
