Métodos:

- void Speak(final String message, final long timeToStart);
- void Speak(final String message, final long timeToStart, boolean shutdownOnFinish);
- void shutdown();

Exemplo de uso:

TextToVoice speak = new TextToVoice(thisActivity.this);
...
speak.Speak("Olá, eu sou seu assistente virtual", 10);

// Ao sair da Activity
speak.shutdown();

OU

speak.Speak("Olá, eu sou seu assistente virtual", 1, true);
OBS:
Speak("msg", 10) = Speak("msg", 10, false)
