More Information

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 Acapela TTS, CereProc CereVoice, Microsoft Azure Speech SSML, Microsoft SAPI 5 XML, and W3C SSML syntax; and
Dynamically switch among speech APIs and syntax formats.

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

Synthesizers (i.e. speech APIs) interpret different markup syntax. VoiceMarkupKit supports the following markup syntax:

Speech API	Markup Syntax
Acapela TTS	AcaTTS Tags
Cepstral Swift	W3C SSML
CereProc CereVoice	W3C SSML, CereVoice Tagset
Microsoft Azure Speech SSML	Azure Speech SSML
Microsoft SAPI 5	SAPI 5 XML Markup, W3C SSML (SAPI 5.3+)
Microsoft Speech Platform	W3C SSML
Microsoft .NET System.Speech	W3C SSML
Microsoft .NET Microsoft.Speech	W3C SSML
Microsoft WindowsMedia (UWP and WinRT)	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, you can:

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

SSML Editing
