SpeechKit

Chant SpeechKit handles the complexities of speech recognition and speech synthesis. The classes minimize the programming efforts necessary to construct software that speaks and listens.

A SpeechKit application can:

Control application functions by speaking rather than having to use a mouse or keyboard;
Prompt users for applicable data capture;
Capture data by speaking rather than typing;
Confirm data capture with spoken or audio acknowledgement;
Transcribe audio files to text; and
Synthesize speech to files.

Recognizers are accessed via proprietary application programming interfaces (APIs). SpeechKit supports the following speech APIs for speech recognition:

Speech API	Platforms
Apple Speech	ARM, x64, x86
Google android.speech	ARM
Microsoft SAPI 5	x64, x86
Microsoft Speech Platform	x64, x86
Microsoft .NET System.Speech	x64, x86
Microsoft .NET Microsoft.Speech	x64, x86
Microsoft WindowsMedia (UWP)	ARM, x64, x86
Microsoft WindowsMedia (WinRT)	x86, x64
Nuance Dragon NaturallySpeaking	x86, x64

Synthesizers are accessed via proprietary application programming interfaces (APIs). SpeechKit supports the following speech APIs for speech synthesis:

Speech API	Platforms
Acapela TTS	x64, x86
Apple AVFoundation	ARM, x64, x86
Cepstral Swift	x64, x86
CereProc CereVoice	x64, x86
Google android.speech.tts	ARM
Microsoft SAPI 5	x64, x86
Microsoft Speech Platform	x64, x86
Microsoft .NET System.Speech	x64, x86
Microsoft .NET Microsoft.Speech	x64, x86
Microsoft WindowsMedia (UWP)	ARM, x64, x86
Microsoft WindowsMedia (WinRT)	x86, x64

Within Chant Developer Workbench, you can:

Enumerate speech engines for testing recognizer-, and synthesizer-specific features;
Trace recognition and synthesis events;
Support grammar activation and testing; and
Support TTS markup playback.
