More Voices For Narrator

Narrator uses all voices which are available from Mac OS X by default. But there is more...

Voices from Cepstral

There is a whole bunch of English and American voices at Cepstral. The trial period is not time-limited; It never expires. However, a voice will interject reminder messages into the audio output until you purchase a valid license key for it. Each single voice has a price of 29.95 USD at Cepstral. [State: 2010-11-30]
