Voice Recognition module stuck when trying to record audio

Post by TechAaron » Sun Aug 11, 2019 5:14 am

I have just received one of the Geeetech Voice Recognition modules and am unable to record commands. Every serial command I try works, except when i send "AA 11" to begin recording, the module returns "Start" over and over again, it never returns "Again" or "No voice" or any other signal, just "Start, Start, Start..." and the only way to stop the device is to unplug the GND or VCC pins and restart it.

Any help would be appreciated.

Thank you

Hi,

here is a screenshot of AccessPort where tried testing the system. i entered AA 00 and the device responded with "waiting!" and then I entered AA 11 so start recording, and it displayed start over and over again and there was no way to stop it without unplugging the module.

Thank you

Hi, you can check the connection between voice recognition module and USB-TTL module is correct.

TXD pin on voice recognition module should be connected to RDX pin on USB-TTL module.

RDX pin should be connected to TXD pin.

If the connection is correct, please check the baud rate of serial software is set correctly.

The baud rate for the voice recognition module defaults to 9600bps.

The baudrate is set to 9600, however I am not using a usb to ttl, I am interfacing through an arduino UNO. I have bypassed the processor on the arduino so it is acting as a usb to TTL, and I imagine that if all of the other commands are working correctly, gathering input from the microphone should also work, but correct me if Im wrong.

Thank you.

You can refer to this:
Write aa 36 in the send area of the serial port software,
and then click Send to switch the serial port receive mode to Common mode.
Finally, the 0xaa11 command is sent to enter the recording of the first group of voices.
