Remarks
When an application calls GetInstalledVoices(), the method verifies that each of the voices it finds meets certain minimum criteria. For any voice that fails verification, GetInstalledVoices() sets its Enabled property to False. An application cannot select a voice whose Enabled property is False. Typically, applications will not set a voice’s Enabled property.
A voice is an installed Runtime Language for speech synthesis (TTS, or text-to-speech). The Microsoft Speech Platform Runtime 11 and Microsoft Speech Platform SDK 11 do not include any Runtime Languages for speech synthesis. You must download and install a Runtime Language for each language in which you want to generate synthesized speech. A Runtime Language includes the language model, acoustic model, and other data necessary to provision a speech engine to perform speech synthesis in a particular language. See InstalledVoice for more information.
The Runtime Languages are different for each version of the Speech Platform Runtime. You must download the Runtime Language version that matches the version of the Speech Platform Runtime that you have installed. The Runtime Languages for the Speech Platform SDK 11 are redistributable and are different than the languages that ship with Windows Vista or Windows 7. Use the following link to download Runtime Languages for version 11 of the Speech Platform Runtime:
See Language Support for a list of languages for which you can download Runtime Languages.
