Explore ways to do more with Nuance Speech Technology.

More Information

Chant Developer Workbench 2020 includes LexiconKit to generate pronunciations for synthesis clarity, SpeechKit to synthesize text to speech, and VoiceMarkupKit to markup text for tailored speech synthesis. It also provides an interative toolset for editing and testing Vocalizer and VoCon lexicons, speech synthesis, and Speech Synthesis Markup Language (SSML).

Develop and test applications that do more with Nuance Speech Technology

Developers use Chant Developer Workbench with LexiconKit to create and edit Nuance lexicons, SpeechKit to test and analyze speech synthesis, and with VoiceMarkupKit to create, edit, and test Speech Synthesis Markup Language (SSML).

Use LexiconKit to create and edit a lexicon of word pronunciations for Nuance voices.

**Vocalizer and VoCon Pronunciation Editing**: Create and edit Vocalizer and VoCon pronunciations faster by using the auto generation feature. Simply type the word, space, and two forward slashes to generate the default pronunciation for editing.

Use SpeechKit to test and analyze speech synthesis with Nuance voices.

**Synthesizer Management**: Enumerate and test synthesizers with live playback or persisting synthesized speech to files.

Use VoiceMarkupKit to create and edit SSML with Nuance voices.

**SSML Editing**: Edit L&H Native Control Sequence, SAPI 5, and W3C Speech Synthesis Markup Language (SSML) faster with built-in intelliprompt that suggest valid markup syntax.
