not gonna lie this is driving me nuts mac Terminal party trick:
- Open Terminal.
- Type
say "I am your computer". - Enjoy.
Useful stuff: say -v ? lists voices, -r changes the speaking rate, and say -o out.aiff "some text" saves the speech to an audio file instead of playing it... i used that last one to make a quick voiceover draft for a slideshow... has anyone used it for something genuinely practical?
