SAPI V5 Notes

·      DECtalk Software for Windows currently supports SAPI Version 5 functions for Windows 98, Windows ME, Windows NT, and Windows 2000; not for Windows 95 or Windows CE.

·      SAPI Version 5 support currently is for U.S. English only.

·      The Context feature currently is not supported. DECtalk accepts the context tags but does not use them.

·      Beginning with SAPI Version 5, you can use DECtalk Software inline commands in SAPI text buffers. For example, you can access a command such as [:tone 500 300] using an XML tag such as <dectalk tone 500 300>.

·      You can use DECtalk Software phonemes in SAPI text buffers. For example: <dectalk phon arpa on][hx’ ehl ow][:phon arpa off>. With DECtalk’s unified phoneme set, you can specify phonemes from different languages within the context of your current language.
