How could I make text to speech using the speaker?

[AndreaF]

I have M5stickC with speaker hat. I'm wondering if it's possible to perform text to speech routines in order to allow the speaker to speak a string.

This works on the M5stack, for the stickC I cannot test tho..

#include <M5Stack.h>
#include <M5StackUpdater.h>
#include <Arduino.h>
#include <ESP8266SAM.h>  //https://github.com/earlephilhower/ESP8266SAM
#include <AudioOutputI2S.h>  //https://github.com/earlephilhower/ESP8266Audio

AudioOutputI2S *out = NULL;

void setup()
{
  M5.begin();
  Wire.begin();
  if(digitalRead(BUTTON_A_PIN) == 0){
    Serial.println("Will load menu binary");
    updateFromFS(SD);
    ESP.restart();
  }  
  out = new AudioOutputI2S(0, 1, 32);
  out->begin();
}

void loop()
{
  ESP8266SAM *sam = new ESP8266SAM;
  sam->Say(out, "Can you hear me now?");
  delay(500);
  sam->Say(out, "I can't hear you!");
  delete sam;
}

Try this for the M5stickC could work, ...

#include <M5StickC.h>
#include <Arduino.h>
#include <ESP8266SAM.h>  //https://github.com/earlephilhower/ESP8266SAM
#include <AudioOutputI2S.h>  //https://github.com/earlephilhower/ESP8266Audio

AudioOutputI2S *out = NULL;

void setup()
{ 
  out = new AudioOutputI2S(0, 1, 32);
  out->begin();
}

void loop()
{
  ESP8266SAM *sam = new ESP8266SAM;
  sam->Say(out, "Can you hear me now?");
  delay(500);
  sam->Say(out, "I can't hear you!");
  delete sam;
}

@chriswr It works on the M5stickC :)

Can you explain the line " out = new AudioOutputI2S(0, 1, 32);" ?
What do the numbers 0, 1, 32 mean?
Thank you.

I see some examples, like here :
https://www.xtronical.com/i2sinternetradio/
There is a line:
// audio.connecttospeech("Wenn die Hunde schlafen, kann der Wolf gut Schafe stehlen.", "de");
It seems to be another way, but you can choose the language.
Could this work on the M5stickC with the SPK HAT?
What do I put on DIN connection, Bit clock, and Left Right Clock?

@chriswr said in How could I make text to speech using the speaker?:

ESP8266SAM *sam = new ESP8266SAM;
sam->Say(out, "Can you hear me now?");
delay(500);
sam->Say(out, "I can't hear you!");
delete sam;

@ChrisWR will this work with ATOM Echo Smart Speaker Development Kit? https://m5stack.com/collections/m5-atom
