Elevate the power of your applications by listening, speaking, and interacting with them. Eliminate the guesswork and uncertainty of integrating speech and natural user interface technology with Chant Developer Workbench.

Design grammars with Chant GrammarKit for high-performance speech recognition that can capture data faster and more accurately than an end-user can type with a keyboard or keypad, click with a mouse, or touch a screen.

It is common for a speech recognizer to mismatch, or a speech synthesizer to mispronounce a person's name, product, part, or location because they are not pronounced phonetically as they are spelled. To correct this problem, a predefined lexicon of pronunciations can help a speech recognizer match accurately and a speech synthesizer pronounce words correctly. Tailor pronunciations for more accurate speech recognition and higher-quality speech synthesis by creating, editing, and distributing lexicons with Chant LexiconKit.

A speaker profile is acoustic data used by a speech recognizer to increase its recognition accuracy for a specific individual's voice and environment. Because these files are constantly updated during speech recognition, they can become corrupted or damaged. It is important to be able to restore the speaker profile or dynamically create a new one on demand to minimize application disruption. Use Chant ProfileKit to administer speaker profiles for more accurate speech recognition.

Integrate Speech Technology for hands-free operation of applications from anywhere an end-user can speak and listen. Chant SpeechKit handles the complexities of speech recognition and speech synthesis to minimize the programming necessary to develop software that speaks and listens.

Text-to-speech (TTS) markup controls speech synthesis speaking qualities such as the speed, pitch, emphasis, and word pronunciation. Fine-tune speech synthesis with Chant VoiceMarkupKit to markup static text or integrate directly in applications to dynamically generate markup for real-time speech synthesis.

VoiceXML is the syntax used in most Voice Response System applications. Use Chant VoiceXMLKit for creating, testing, and debugging VoiceXML offline before deploying to servers. Win over your audience with enriched communications by dynamically generating caller-tailored VoiceXML with VoiceXMLKit at runtime.
