About Chant Developer Workbench

Develop Software that speaks, listens and interacts with users.

Chant Developer Workbench helps you develop applications that speak, listen, and interact with users. You can easily manage conversations, grammars, lexicons, movement, profiles, speech, and text-to-speech markup directly within application software you develop. Chant Developer Workbench is comprised of tools and class libraries for integrating speech and natural user interface technology.

Chant Developer Workbench Features

The Chant Developer Workbench toolset provides development and testing environment for working with:

  • GrammarKit
  • KinesicsKit
  • LexiconKit
  • ProfileKit
  • SpeechKit
  • VoiceMarkupKit
  • VoiceXMLKit

Interactive Development Environment Chant Developer Workbench provides a comprehensive development and testing environment for working with speech and natural user interface technology that features:

  • Multi-document, interactive, customizable environment
  • Powerful editor with color-coded formatting, intelliprompt, optional outlining, optional line numbers, undo-redo, word wrap, and find/replace
  • Resource browsers for testing
  • Event tracing

The tabbed-document interface provides for fast switching among multiple documents and browsers. The editing environment is designed to accelerate speech technology grammar and markup development with built-in syntax checking and prompting. The multi-docked windows layout is configurable to yield productivity for various development and testing scenarios. Toolbars can be easily customized to display the facilities most often used. Window layout and toolbar settings are persisted across executions.

Feature Summary

Chant Developer Workbench is comprised of essential tools and class libraries for developing software that speaks, listens, and interacts with users. It provides an IDE for developing and interactively testing speech and natural user interface technologies. You can manage conversations, grammars, movement, profiles, lexicons, speech, and text-to-speech markup directly within application software you develop and deploy.
