More Information

The goal of lexicon management is to adjust to the end user manner of speaking for enhanced speech recognition accuracy and speech synthesis quality. A LexiconKit application can:

  • Create word pronunciations on demand;
  • Edit lexicon word pronunciations for ensuring maximum recognition accuracy and speech synthesis quality; and
  • Speak lexicon word pronunciations to fine-tune definitions.

Chant LexiconKit handles the complexities of generating word pronunciations. This allows applications to enhance the quality of speech recognition and speech synthesis and offer administrative features for maintaining word pronunciations.

Recognizers and synthesizers have unique formats for word pronunciations, lexicon formats, and approaches for runtime inclusion. LexiconKit supports the following recognizer and synthesizers and their lexicons formats.
