Software FAQs

Q: Can CereProc voices be run on OSX Yosemite?

A: CereProc voices for Apple Mac OSX can be run on Intel Macs running Leopard, Snow Leopard, Lion, Mountain Lion, Mavericks and Yosemite. If you have an older release of a CereProc voice, it may not be compatible with more up-to-date versions of Mac OSX.

Q: When I install a downloaded voice, it prompts me for a license. Where do I get the license from?

A: The license key for each of the purchased voices is sent in the invoice email, immediately after the purchase of a voice. If you did not receive, or have deleted the email, please contact CereProc using the Support form.

Q: I wish to forward the license key CereProc sent me to another email address. Can I do this?

Forwarding the CereProc license key to another email address may corrupt the license key. If you have a requirement to do this, the best way to access the license is to log in to your account, click on
My Account>Orders, then click on the number of the invoice in question, then click Invoice. At the bottom of the invoice, you will find the license key.

If you do not hear any speech output, make sure your headphones/speakers are plugged in and that the system volume is turned up.

On Macs, users should go to System Preferences/Speech, select a CereProc voice from the System Voice dropdown, and then press Play.

For other tasks such as screen reading, pdf reading, saving audio out to wav files, a third party piece of software can be used. Here is a list of some compatible applications, some of which are free, some of which require payment:

Q: How can I change the path that CereProc voices are installed to?

A: By default, CereProc voices are installed in c:\Program Files\CereProc. During installation, the user can choose a Custom install and this permits the user to specify which directory the voice is installed in.

Q: I've found a bug in one of the voices. How can I report it to CereProc?

A: Registered users can submit bugs to support using the support request form

Q: I have downloaded a Windows voice and when I try to run the installer, it doesn't start.
