LexiconKit

What is Lexicon Management?

Lexicon management enables you to:

• tailor pronunciations to specific end user preferences.
• extend recognizer and synthezizer lexicons, and
• create, delete, edit, import, and export lexicons as part of your deployed applications.

Application benefits include:

• improved speech recognition accuracy and
• enhanced speech synthesis clarity.

What is LexiconKit?

Chant LexiconKit handles the complexities of managing lexicons and persisting them in files for deployment and installation.

The LexiconKit class library includes a lexicon management class that provides you a simple way to create, edit, export, and import lexicon word pronunciations. Your application can edit lexicons as part of its runtime operation to enable real-time customisation and tailoring of your speech recognition and speech synthesis environment.

It simplifies the process of managing word pronunciations for Cepstral Swift API, Microsoft SAPI 5, Microsoft Speech Platform, and Nuance Vocalizer and VoCon API lexicon formats to use with your favorite speech recognizers and synthesizers.

LexiconKit includes C++, C++Builder, Delphi, Java, .NET Framework, and Silverlight class library formats to support all your programming languages and sample projects for popular IDEs—such as the latest Visual Studio from Microsoft and RAD Studio from Embarcadero.

The class libraries can be integrated with 32-bit and 64-bit applications.

Features

• Edit locally installed lexicons;
• Create and delete lexicon word pronunciations on demand;
