Hello everyone
I am currently working on a voice control related project. In the beginning, after the first firmware, it worked well.
Now voice control is well-stitched, but when I connect it to the esp8266 nodemcu microcontroller, it does not work.
Can you please help? thank you in advance!
Schematics please.
Scheme
Full code
byte com = 0;
void setup() {
Serial.begin(9600);
Serial.write(0xAA);
Serial.write(0x37);
delay(1000);
Serial.write(0xAA);
Serial.write(0x21);
}
void loop() {
while (Serial.available()) {
com = Serial.read();
switch (com) {
case 0x11:
Serial.println("command1");
break;
case 0x12:
Serial.println("command2");
break;
case 0x13:
Serial.println("command3");
break;
case 0x14:
Serial.println("command4");
break;
case 0x15:
Serial.println("command5");
break;
}
}
}
Hi,
What is this?
Can we please have a circuit diagram?
An image of a hand drawn schematic will be fine, include ALL power supplies, component names and pin labels.
A UNO is not an ESP8266.
Tom... 
Yes, sorry, I didn't find esp8266 in the scheme, and put arduino uno 
Here is the information:
And information in YouTube:
Hi,
That video is being conducted by someone who doesn't know the first thing about Arduino.
You do not connect LEDs directly to Arduino outputs.
Can I suggest you get a UNO and get it working before trying to port to ESP8266?
You have got Tx connected to RX, and Rx connected to Tx between the units?
Have you got the baud rate for the module right to communicate with the controller?
Thanks.. Tom..
Just a tip:
The specs shown at https://www.geeetech.com/wiki/index.php/Arduino_Voice_Recognition_Module says the module works with 5V logic. ESP 8266 is a 3.3V device. That means you will have to provide separate power to the module and take care of the 5V signal that TX line of the module sends to ESP 8266 RX line (using a voltage divider for example).
Yes, Rx is connected to Tx, TX is connected to RX.
And correctly
Have got the baud rate for the module right to communicate with the controller
We supply the esp8266 with 5 volts via VIN.
The voice module is connected to the pin VIN
Make a separate power supply, but gnd connected together?
Can I please get a voltage divider circuit?
That´s ok. So 5V power is going to ESP 8266 Vin and the module, as in your diagram in post #3.
If you provide separate power, all grounds might be connected together. But it´s already done in post #3 diagram.
Google offers lots of material on that. Here is one of them:
https://learn.sparkfun.com/tutorials/voltage-dividers/all
I made a separate power supply, and it partially works.
Only team 4 recognizes well. The rest are randomly selected by mistake, sometimes even ignores
A voltage divider has been added. The circuit even stopped working. That is, the voice control does not see the microphone.
Can you please recommend a speech recognition module that is well suited for arduino or for esp?
Hi,
Can you please post some images of your project so we can see your component layout?
Thanks.. Tom...
I´m sorry, I haven´t worked with speech recognition modules before in order to give you a suggestion. But the one you´re using seems to be appropriate (the manual clearly says it is Arduino compatible). I believe you should still try to find where the problem with your setup is before giving up using this module that you already have.
Apparently there are no problems in your setup provided that (+) and (-) cables are correctly connected.
You mean, you´ve recorded the 5 commands of Group 1 and after that the module was able to identify them properly?
At post #1 you show a picture of a terminal and the process of recording and importing Group 1 of commands. After that, with the full code provided on post #3, you should be speaking to the module and checking the results on Serial Monitor of Arduino IDE, which is shown at post #8.
So, what exactly is wrong? This 
?
Well, regarding the module manual we can see some interesting things:
"Please note that speaker independence requires strictly good MIC. The MIC we supply is not good enough for it to be speaker-independent" (p1, Introduction).
"Try to record and use it in the same environment. And noise could greatly reduce the recognition rate." (p8)
"I found occasionally this module could not distinguish “red” and “green”. Then I changed the MIC" (p9)
"Also I find that it is a little hard for this module to distinguish “of” and “off”. To distinguish those two similar pronunciations, high-sensitive MIC is required and speaking must be very clear, as well as in quiet environment. All those limitation makes low practicality. But there are simple ways to solve it. Make your voice instructions distinctive. Do not use voice instructions of similar pronunciation" (p9)
Maybe the next step will be trying a better mic, erasing the previously recorded Group 1 and recording it again.
Another challenge would be to create a specific program to record commands via ESP 8266 instead of the suggested Serial Tool.
Yes, I recorded 5 commands in group 1, and after that the module was able to identify them correctly
The recorded fourth command is in group 1, only its module recognizes it well.
Okay, then I'm going to look for a good microphone now
Do you mean writing commands inside the arduino ide?
https://www.youtube.com/watch?v=zCEYxSdYBcA&list=LL&index=6
Like this?
But it's true that this is another new module.m
I changed the microphone to a better one. The situation is the same. The module recognized only one command. And this is by chance. Repeated the same phrase, ignored
