Example Code for Arduino-Speech Synthesis via I2C

Hardware Preparation

• DFRduino UNO R3 (or similar) x 1
• Gravity: Speech Synthesis module V2.0(Support English and Chinese) x1
• Jumper wires

Software Preparation

• Arduino IDE
• Download and install the DFRobot Speech Synthesis Library. (About how to install the library?)

Wiring Diagram

Other Preparation Work

Dial the switch to I2C.

  //Init speech synthesis sensor
  ss.begin();
  //Set voice volume to 5
  //ss.setVolume(5);
  //Set playback speed to 5

  //Set tone to 5
  //ss.setTone(5);
  //For English, speak word 
  //ss.setEnglishPron(ss.eWord);
}

void loop() {
  ss.speak(F("She sells seashells by the seashore"));
  ss.speak(F("Hello, I'm Speech Synthesis module"));
  ss.speak(F("a b c d e f g"));

  /*Use text control identifier*/
  //Voice volume identifier 
  //ss.speak(F("[v3]Hello [v8]world"));
  //Word Pronounce mode identifier 
  //ss.speak(F("[h1]Hello [h2]world"));
}

Result

The speaker of the module plays English on a loop.
