Chant SpeechKit includes components for managing speech recognition and synthesis. Whether you develop desktop, server, mobile, telephony, Internet software, or web pages, SpeechKit components can transform text to speech for audio playback and speech to text for your software to process. This liberates your software from keypads, keyboards, etc.. as primary input devices by letting end users talk with it.

With Chant SpeechKit component software, you can:

• Voice-enable any type of Win32, Win64, and WinCE application with SpeechKit components in ActiveX, C++Builder, C++, Delphi, Java, .NET Framework, Silverlight, and Web formats.
• Develop and deploy your applications independent of specific recognizers:
  • Nuance Dragon NaturallySpeaking,
  • IBM SMAPI (ViaVoice),
  • Microsoft SAPI 4, SAPI 5, and
  • Nuance VoCon 3200.
• Develop and deploy your applications independent of specific synthesizers:
  • Acapela BabTTS,
  • Cepstral Swift,
  • Microsoft SAPI 4, and SAPI 5
  • Nuance RealSpeak Solo, and
  • Nuance Vocalizer.
• Select and adjust recognizer, synthesizer, and audio options and property settings dynamically.
• Leverage a common persistence framework across programming languages and component formats.
• Support Unicode and ANSI systems with single component library.

Develop Applications that Speak

• Synthesize speech from anywhere within your application
• Automatically synthesize message box text
• Easily enumerate and select a voice
• Easily adjust the spoken output speed, volume, and pitch
• Take advantage of built-in audio management and synthesize to the audio format needed by your application
• Synthesize text from strings, buffers, streams, and files
• Playback audio or write to buffers, streams, and files
• Access detailed synthesis result attributes and properties
• Persist property settings across executions
• Process requests synchronously or asynchronously with built-in queue manager

Develop Applications that Listen

• Capture spoken input as if it was typed using a keyboard
• Select menus, list items, click buttons, and click hypertext links by speaking instead of using a mouse
• Simulate keyboard input and mouse clicks
• Recognize spoken languages supported by recognizers
• Leverage common dictation text formatting across speech APIs
• Access detailed recognition result attributes and properties
• Correct recognition results
• Playback recorded audio associated with recognition results
• Manage context-based and context-free recognition by dynamically adding, removing, enabling, and disabling, command, grammar, and dictation vocabularies
• Take advantage of built-in audio management and recognize from the audio format needed by your application
• Recognize from buffers, files, microphone (live), and stream audio sources
• Write audio to buffers, streams, and files.
• Persist property settings across executions.
• Process requests synchronously or asynchronously with built-in queue manager.
• Use built-in What Can I Say dialog to display what commands your application responds to and Where Can I Go dialog to display hypertext links that can be invoked by speaking the link text

Interactive Environment

Within Chant Developer Workbench interactive environment, you can:

• Enumerate speech engines for selection and command line testing of recognizer- and synthesizer-specific features
• Trace recognition and synthesis events
• Support grammar activation and testing (requires GrammarKit)
• Support TTS markup playback (requires VoiceMarkupKit)
