I tried uploading the code, code is uploading but module is not recognizing the voice. I have trained the module. May I know what would be the reason.

Hello

before we even try to understand what you did, do yourself a favour and please read How to get the best out of this forum and post accordingly (including code with code tags and necessary documentation for your ask like your exact circuit and power supply, links to components etc).

PS/ this sounds like a very bad idea

while (1)
{
  int i = 0;
  Serial.println(buf[i]);
  i++;
}

Just I wanted to see what’s happening. So I tried that at last stage.

Could you fix the first post and add the code tags please...

Okay!

While you are uploading the code using code tags also upload an annotated schematic showing how this is wired. Be sure to show all connections, devices, power sources, ground connections and note any leads over 10"/25cm.
