OS X only offers US English text-to-speech voices, and they are not of a very high quality. Apple’s voices are OK to listen to for short passages like getting your computer to speak the time, but if you use text-to-speech very much you’ll probably want to purchase a higher quality voice. Leopard’s “Alex” voice is a great improvement on the ones available before Leopard came out, but even that voice is jarring and mechanical to listen to for more than a few minutes and only offers American English. So what are your alternatives for text to speech?
Note: “System Voices” mean that the voice can be used in any program that has text-to-speech ability and can be used with VoiceOver or to speak selected text. You won’t see them as a separate program, the voice will appear in the list of voices on your computer.

@Patricia: What have you tried to get rid of it and what hasn’t worked? If you have read all the instructions and followed them and that hasn’t worked I suggest you email the ConvenienceWare people for help but I’m willing to try if you let me know what’s happening.
Please help me get rid of 15 day trial of mac “ghostreader,
as it is driving me mad.
please help. thank you
According to the Japanese Dtalker site, they have fixed the problems with Leopard with their new update. Just thought you’d like to know.
@Jason: Thank you very much! That’s great to know. Do you use DTalker yourself, or know anybody who does?
A Scottish company called CereProc also sells system voices for Mac OS X:

In addition to the ones on their store, many more voices were demoed at this year’s WWDC, including one called “George” based on the voice of a certain individual from Crawford, TX.
@Nicholas: Thanks for that information, I’ll add them to my various lists as soon as I can. I would adore to have a Scottish voice on my computer – the “Heather” voice is brilliant!
is there a possibility of downloading heather for free somewhere… I would pay if I had the money but being a student leaves me quite broke and the 30 pounds can last me a week and a half on food. it is however possibly the best addition to my study ritual.
