I am using TTSlib, but the main draw() loop seems to be paused while it is actually saying something. For instance, in the following demo, it stops outputting the millis()

Is there a simple way around this, or would the only solution be to have the call to TTSlib in a separate thread ( http://wiki.processing.org/w/Threading)?

1. import guru.ttslib.*;
2. TTS tts;
3. void setup() {
4.   size(100,100);
5.   tts = new TTS();
6. }
7. void draw() {
8.   println(millis());
9. }
10. void mousePressed() {
11.   tts.speak("Hi! I am a speaking Processing sketch");
12. }

Is there a library which provides a box(x1, y1, z1, x2, y2, z2) function (similar to the line(x1, y1, z1, x2, y2, z2) one) and works out the size and rotation of the box, rather than needing me to calculate it (or which would help with the calculations)?
