Do More with Nuance Speech Technology

Complimentary architecture review

Chant software and services enables you to do more with Nuance speech technology. Start talking with your applications using Nuance recognizers and synthesizers in a matter of minutes. It's that easy.

Or, if you prefer, have Chant provide you the code to drop into your applications and start talking with them with little or no effort on your part at all.

Chant application-ready class libraries simplify using the Nuance Dragon NaturalSpeaking and VoCon 3200 SDKs.

In addition to supporting the features provided by these two recognizers, your applications can also take advantage of Chant features not implemented in either recognizer's SDK such as:

  • Manage context-based and context-free recognition by dynamically adding, removing, enabling, and disabling, command, grammar, and dictation vocabularies.
  • Select and adjust recognizer and audio options and property settings dynamically.
  • Leverage a common persistence framework across programming languages and component formats.
  • Integrate with almost any application type, architecture, programming language, and development environment used for Windows platforms.

Chant application-ready class libraries simplify using Nuance Vocalizer voices. Nuance Vocalizer voices can be accessed using the Nuance Vocalizer SDKs: Automotive, Expressive, Mobile, and Network.

The benefit of using the Chant class libraries is that your applications can take advantage of Chant features not implemented in the speech SDKs such as:

  • Control synthesis requests with built-in queue manager.
  • Synthesize from a variety text data input formats and generate audio data in a variety of output formats.
  • Select and adjust synthesizer and audio options and property settings dynamically.
  • Integrate with almost any application type, architecture, programming language, and development environment used for Windows platforms.
  • Synthesize and playback audio from Vocalizer voices with a single application request.

Design Grammars for High-performance Recognition with GrammarKit

Design grammars for high-performance speech recognition with GrammarKit

Now you can easily compile and persist SAPI CFG, Nuance L&H BNF+, W3C ABNF, and Java Speech Grammar Format (JSGF) grammar binary within your applications using GrammarKit from Chant. Your Dragon NaturallySpeaking and VoCon 3200 applications can:

  • Compile grammar source from buffer, file, resource, stream, and string formats.
  • Persist compiled grammar binary to buffer, file, and stream formats.

With GrammarKit in the Chant Developer Workbench, you can:

  • Create and edit grammars in native grammar syntax.
  • Compile and debug grammars.
  • Test grammars with live and recorded audio (requires SpeechKit).

  • Recognize spoken languages supported by recognizers.
  • Access detailed recognition result attributes and properties.
  • 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.

You can easily manage Vocalizer voices within your applications using SpeechKit from Chant. Your applications can:

  • 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.
