Overload List
| Name | Description | |
|---|---|---|
 | GetInstalledVoices()()()() | Returns all of the installed speech synthesis (text-to-speech) voices. |
| GetInstalledVoices(CultureInfo) | Returns all of the installed speech synthesis (text-to-speech) voices that support a specific locale. |
Remarks
The Microsoft Speech Platform Runtime 11 and Microsoft Speech Platform SDK 11 do not include any engines for speech synthesis in a specific language. You must download a language pack (an engine for speech synthesis in a specific language) for each language in which you want to generate synthesized speech.
The language packs are different for each version of the Speech Platform Runtime. You must download the language pack version that matches the version of the Speech Platform Runtime that you have installed. The language packs for the Speech Platform SDK 11 are for server-based applications and are different than the languages that ship with Windows Vista or Windows 7. Use the following links to download the version of the server language packs that match your Speech Platform Runtime version:

Speech synthesis is often referred to as text-to-speech or TTS. An installed TTS engine is also referred to as a voice. A language pack for speech synthesis contains a TTS engine, or voice. When an application calls GetInstalledVoices()()()(), the method verifies that each of the voices (engines for text-to-speech) it finds in the registry 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. |
