The goal of text-to-speech markup is to enhance the quality of the text-to-speech playback. With Chant VoiceMarkupKit, you can:

Generate markup language in Microsoft SAPI 5 XML, Nuance L&H Native Control Sequence, and W3C SSML syntax;
Generate pronunciation phonemes for Cepstral, Microsoft SAPI 5, Microsoft Speech Platform, and Nuance Vocalizer synthesizers.
Dynamically switch among speech APIs and syntax formats.

Chant VoiceMarkupKit handles the complexities of generating text-to-speech markup for various markup syntax. This enables you to tailor speech synthesis to produce sounds in familiar dialects, speaking patterns, and accents of your end users. You can adjust TTS markup as needed for the synthesizer to enhance the playback quality when synthesizing.

Synthesizers (i.e., speech APIs) support unique markup syntax. VoiceMarkupKit supports the following synthesizers and their markup syntax:

Synthesizer	Speech API	Markup Syntax
Cepstral (all languages)	Cepstral Swift	W3C SSML
Microsoft SAPI 5 (all languages)	SAPI 5	SAPI 5 XML Markup, W3C SSML
Microsoft MSP (all languages)	MSP	W3C SSML
Microsoft Universal Windows Platform (all languages)	Windows Media	W3C SSML
Nuance Vocalizer Automotive (all languages)	Nuance Vocalizer Automotive	L&H Native Control Sequence, SAPI 5 XML Markup
Nuance Vocalizer Expressive (all languages)	Nuance Vocalizer Expressive	L&H Native Control Sequence, SAPI 5 XML Markup
Nuance Vocalizer Mobile (all languages)	Nuance Vocalizer Mobile	L&H Native Control Sequence
Nuance Vocalizer Network (all languages)	Nuance Vocalizer Network	L&H Native Control Sequence, SAPI 5 XML Markup, W3C SSML

By generating TTS markup at runtime, your application can maximize the quality of TTS playback and offer your end users the flexibility of using various synthesizers with your application.

Within Chant Developer Workbench interactive environment, you can:

Create and edit documents with TTS markup;
Generate TTS markup;
Generate word pronunciation phonemes;
Edit word pronunciation phonemes (requires LexiconKit); and
Playback text with TTS markup (requires SpeechKit).
