Notes:
· A Text-to-Speech voice is closely associated with a particular speech engine. It may not be clear from the displayed name which language a voice is using. After selecting a speech engine or voice, test the voice and language by clicking Preview Voice.
· The language or voices supported by a speech engine may not be obvious from the engine's displayed name. Refer to the specific user's guide for detailed information about the engine. This includes not only the language supported, but also the lexicon purpose. The lexicon purpose indicates whether it is a general grammar or jargon specific to a profession such as legal or medical.
· Microsoft does not provide additional speech engines (voices), but a number of third-party products are available that support the new Microsoft Speech API. For information on these products, visit the following Microsoft Web site:

The KB article shows for windows XP and vista only but for windows7 also it remains same. (http://www.microsoft.com/speech/evaluation/thirdparty/engines.mspx)
