p5.speech Example: Create Speech Synthesis

var foo;

​

function setup() {

  // speech synthesis object

  foo = new p5.Speech();

  // function sets callback to fire when synthesis voices are loaded

  foo.onLoad = voicesLoaded;

  // It is suggested to put everything after the voices are loaded

}

​

function voicesLoaded(){

  // debugging statement

  // Lists available synthesis voices to the JavaScript console.

  // only works when voices are loaded

  foo.listVoices();

  // sets synthesizer voice by number (see listVoices()) or by name; equivalent to the default_voice parameter passed with the constructor.

  foo.setVoice('Google US English');

  // sets the language interpreter for the synthesizer voice.7; Default is 'en-US'

  // the default argument is 'en-US'

  // this function accepts BCP-4 arguements

  // read more about BCP-4 language tags @ https://www.w3.org/International/articles/language-tags/

  foo.setLang('en-US'); 

  // sets playback pitch of synthesized speech

  // from 0.01 (very low) to 2.0 (very high)

  // Default is 1.0; not supported by all browser / OS combinations.

  foo.setPitch(1); 

  // sets rate of speech production

  // from 0.1 (very slow) to 2.0 (very fast)

  // Default is 1.0; not supported by all browser / OS combinations

  foo.setRate(1); 

  // sets synthesizer volume

  // in the range of 0.0 (silent) to 1.0

  // default=max volume.

  foo.setVolume(1);

  // boolean to set whether the speak() method will 

  // interrupt (true) or queue after (false = default) existing speech currently being synthesiz

  foo.interrupt = false;

  // ask the synthesis to say something

  // instructs the synthesizer to speak the string encoded in utterance.

  // Depending on the interrupt property

  // additional calls to speak() will queue after or interrupt speech actively being synthesized

  // When synthesis begins, the onStart() callback will fire; when synthesis ends, the onEnd() callback will fire.

  foo.speak('This is when after voices are loaded.');
