New Features

• Added support for an optional language parameter passed to a built-in grammar.
• Added support for custom language and acoustic models.
• Added support for base model version.
• Added support for certain vendor-specific parameters, including 'speech-start-timeout'. See section 4.7 in the Usage Guide.
• Added support for the content type 'text/grammar-ref-list'.
• Added support for numerous new parameters settable per recognition request to the service such as 'word-confidence', 'timestamps', 'speaker-labels' and others. The parameters can be set globally in umswatsonsr.xml and be specified per recognition request either via vendor-specific parameters or optional attributes passed to a built-in grammar or via metadata set in an SRGS XML grammar. See the Usage Guide.

Fixed Problems

• Make sure START-OF-INPUT is sent before sending RECOGNITION-COMPLETE with a completion cause set to 'no-match' or 'success'.
• Do not set speech/result flag if the detector is already in the complete state. This could result in an attempt to send another audio chunk, when the input completion was already signaled.
• Compose the header field Waveform-URI based on the protocol version. Before, the format defined in MRCPv2 was used unconditionally.
• Fixed output format of an RDR to strictly conform to JSON.

Configuration Parameters

• Added new configuration parameters 'language-customization-id', 'acoustic-customization-id', 'base-model-version', 'customization-weight', 'word-confidence', 'timestamps', 'speaker-labels', 'redaction', 'processing-metrics', 'processing-metrics-interval', 'audio-metrics'.

Miscellaneous

• Updated the Usage Guide to reflect the changes introduced in this release.
