I have rigged up the circuit what has been given in the datasheets. But in the datasheets the details for the traininng mode and recognization mode has not been given properly.
So in the datasheets it is given that
Step1: The 12 word memory banks must be cleared after power on and before store word.At the begin of store word mode LED1 and one of the PortA ( 1~12) whcih is corresponed to selected word bank is active. and AP7003-02 will go to recognization mode after input voice is stored into word bank.( So for that I am making use of push-button switch provided to the PIT4 pin. After I press the LED1 starts blinking and after some seconds LED2 gets ON.How can I store the word in to memory bank .)
Can anyone kindly help me this matter.

Here I enclosed the rapid-share link for the datasheets and the schematics.

In the datasheet there is no information given regarding clock and other things. how it is to be connected and how micro can read data.
I think you reconsider what shailesh said and contact the vendor for more information. You have bought IC from them so you must get full support.]]> contact@nospam.com (Ajay Bhargav) Tue, 06 May 2008 15:16:04 -0700 http://www.8051projects.net/forum-t9290.html Re: Voice Recognization Chip AP7003-02 http://www.8051projects.net/forum-t9290.html

Hi...try following this sequence...
- Power On
- Press PIT4 switch
- Press '1' in keypad
- Speak into the mic to record into bank1(LED1 should be active during this period)
- Then press '2' for selecting bank2 and when LED1 is active speak into the mic to record.
Similarly proceed with other words.
Then press '9' or '10' to select threshold level and go into recognition mode.
In recognition mode LED1 will be active again waiting for an input word in the mic.
Then if the input word matches any stored word,LED2 and the corresponding port pin will become active.Else LED1 will flash to indicate no match and then again revert to recognition mode.
If a match was found and LED2 had become active,it will remain in tht state for 3 minutes and ten revert to recognition mode.If you want the recognition cycle before the 3 min. are over you may press '11'.
Do give a try and report.

Thanx so much for the reply
There was a slight mistake with hardware circuit what i did and now it is working fine.

These are the steps what i concluded with 3x4 Matrix kepad mode configuration.

Fir this first we need to train this chip for the words and after that only recognization process will be done by the chip

Step1: Power On the System

Step2: Press PIT4 Switch
( Led1 will be active to indicate that all the 12 memory banks are cleared and go to the Training mode and after that LED1 will be continuosly active)

For Training the chip

Step3: Press 1 in Keyapd ( for storing the word in memory bank1)

Step4: Speak into the mic to record into bank1 of word length of maximum of 1.5sec long (LED1 will blink once to indicate that word has been stored in the Memory bank and automatically goes to recongization mode

Step5: Press 2 Keypad ( For Storing the word in memory Bank2)

Step6: Same as Step4

Similrly proceed for the other words to store it in a different memory banks

For Recognization mode
In recognition mode LED1 will be active again waiting for an input word in the mic.
Then if the input word matches any stored word, LED2 will be high and perticular memory bank where this recognized word has been stored will be the o/p on the Port A by clearing of the perticular port pin . Else LED1 will flash for the 3 seconds to indicate no match and then again revert to recognition mode.
If a match was found and LED2 had become active, it will remain in that state for 3 minutes and then revert to recognition mode.

Tell us one thing...does it retain the recording even after power off?
And what's the cost of the chip?]]> contact@nospam.com (Ajay Bhargav) Wed, 07 May 2008 17:45:29 -0700 http://www.8051projects.net/forum-t9290.html Re: Voice Recognization Chip AP7003-02 http://www.8051projects.net/forum-t9290.html I bought this chip ( AP7003-02) from NSK Electronics Bangalore and it costs around Rs.200/ or

Can anyone tell me the Memory Bank what this Chip is having volatile or Non-volatile memory since in the datasheet it is not mentioned.


After power Off I tried continuosly with telling the same word what has been recored previously but the LED1 will be continusly OFF means it is not any input word. That is what I confused whether the recording will retain after the power goes Off. Can anyone help me in this.

Previously I put 33pf Capacitor across the A1outpin and A1IN pin and now I changed that one to 330pf given in the schematics. After that the recognization works superb even with far distance.
In this i got confused with 3 things
1. After I switch off whether the previosuly recorded voice retains or not.
2. Regarding the key 10 and key11 for recognization threshold level. what is that recognization threshold level
3. Once the voice has been recognied If PIM2 =0 means auto mode will be selected and o/p will be cleared after 3 minutes or Key 11 has been given for clearing the o/p manually once the voice has been matched. I want to do this from the controller. and for my robotic application I can't wait for 3 minutes to recogniza the next word.

Can anyone help me regarding the above doubts.

switch it off and check it

2. Regarding the key 10 and key11 for recognization threshold level. what is that recognization threshold level

I think recognition threshold level is tolerance of of system. or say acceptable error level of system. I am not able to find perfect words for it

give key 11 to controller GPIO
I think controller interface is going to be totally different not like this typical application using keypad.]]> contact@nospam.com (Ajay Bhargav) Fri, 09 May 2008 14:43:46 -0700 http://www.8051projects.net/forum-t9290.html
