The language used by either speech recognition (SR) or text to speech (TTS) is dependent on the respective engine. A system may have multiple engines loaded at the same time. In addition, multiple engines of the same language may also be present. However, only one engine of each type (SR and TTS) can be active at a given time. You may decide a particular engine better meets your requirements and use that engine more often. Once an engine is set, it is not usually necessary to change it.
To change an SR language:
- In Control Panel, double-click the Speech icon.
- On the Speech Recognition tab, change the SR language by changing the SR engine.
To change a TTS language:
- In Control Panel, double-click the Speech icon.
- On the Text To Speech tab, change the TTS language by changing the TTS engine.
Notes
- A TTS voice is closely associated with a particular engine. It may not be clear from the displayed name which language a voice is using. After selecting an engine or voice, click Preview Voice to test the voice and language.
- The language supported by an engine may not be obvious by 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 by the engine, 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.
- To open a Control Panel item, click Start, point to Settings, click Control Panel, and then double-click the appropriate icon.
