SimpleSpeech is a Processing Library for Speech Synthesis and Speech Recognition, based on the great work by Bryan Chung.

I upgraded and extended Byan’s original library to make it Processing 2.x / 3.x compatible and added some new functionality.
The library has been tested up to version 3.4.

It’s a wrapper for the Java libraries:

• FreeTTS (Speech Synthesis)
• CMUSphinx (Speech Recognition)

Usage

Download and install the SimpleSpeech library in your processing / libraries folder.

Simple example for the Speech Synthesizer (A Processing sketch):

// IMPORT THE LIBRARY
import simpleSpeech.*;
// SPEAKER
Speak speaker;
void setup() {
  speaker = new Speak(this, "kevin16");
  speaker.speak("Hello World!");
] // setup()

Simple example for the Speech Recognizer:

// IMPORT THE LIBRARY
import simpleSpeech.*;
// LISTENER
Listen listener;
void setup() {
   listener = new Listen(this, "\\sample.config.xml");
} // setup()
void draw() {
} // draw()
void listenEvent(Listen _l) {
  String s = _l.readString();
  if (s != null) {
    if (s.equals("hello")) println("I recognized HELLO!");
  } // if (s != null)
} // listenEvent()

Grammar

The grammar (Java Speech Grammar Format, JSGF) for the recognition is defined in the file sample.gram (in the data folder of your sketch).

Example of the grammar file:

grammar sample;
public <command> = <word> | <color> | <shape>;

<word> = (hello)
<color> = (red | blue | green | yellow);
<shape> = (circle | square);

Speech Recognition Configuration

The configuration for the Speech Recognition in deis stored in a file called sample.config.xml in the data folder of your sketch.

IMPORTANT:
Make sure the location of your grammar file is pointing to your data folder in sample.config.xml!
