The plugin is based on the following components:

  • Allow 'builtin:speech/$name' and 'builtin:grammar/$name' to be used interchangeably.
  • Accept SRGS speech grammars without processing of any rules defined in the grammar.
Fixed Problems
  • None.
Configuration Parameters
  • Added a new attribute 'skip-unsupported-grammars', which defaults to 'true'.
  • Added a new attribute 'transcription-grammar', which defaults to 'transcribe'.
  • Changed the default configuration parameters to improve barge-in experience.
  • Improved the speech and DTMF input detector.
  • Changed grammar referencing routine to be, by default, tolerant to malformed and not supported grammars.
