v1.5.0: Improved Recognition Confidence Estimation

You can subscribe to announcements on Gitter: see instructions.

Notes

• Improved Recognition Confidence Estimation: two new, different measures:
  • confidence: basically the difference in how much "better" the returned recognition was, compared to the second best guess (>0)
  • expected_error_rate: an estimate of how often similar utterances are incorrect (roughly out of 1.0, but can be greater)
• Refactoring in preparation for future improvements
• Various bug fixes & optimizations
