Integrate interactive technologies faster with Chant Developer Workbench

Application-ready development tools, libraries, examples, and support for deploying highly interactive technologies where needed.

Develop Highly Interactive Software

When building applications, it's essential that you have the right tools to get the job done.

Now you can develop applications that speak, listen, and interact with users using Developer Workbench from Chant. 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.

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

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; and
  • 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
