Remarks
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.
If none of the installed voices support the specified locale, this method returns an empty collection.
The Microsoft Speech Platform SDK 11 accepts all valid language-country codes as values for culture. For a given language code specified in the culture parameter, a speech synthesis Runtime Language that supports that language code must be installed to correctly pronounce words in the specified language.
If the culture parameter specifies only a language code, (such as "en" for English or "es" for Spanish), and not a country/region code, then any installed speech synthesis voice that expresses support for that generic, region-independent language may produce acceptable pronunciations for words in the specified language. See Language Identifier Constants and Strings for a comprehensive list of language codes.
