New Features

• Implemented an alternate way of referencing built-in grammars via 'special' ruleref in SRGS XML grammars. See Section 5.1 in the Usage Guide.
• Added support for 'xml:lang' attribute optionally specified in SRGS XML grammars. This method has the highest precedence in selection of recognition language. The language can be otherwise specified either by the global configuration parameter or the header field 'Speech-Language'. See Section 4.2 in the Usage Guide.
• Added a new attribute 'language' to individual speech contexts, which allows to define speech contexts for various languages regardless of the global configuration parameter.

Fixed Problems

• Using HTTP GET instead of HTTP POST to retrieve an access token. Although both methods were apparently accepted by IBM Watson in the past, only HTTP GET has always been documented and is currently functional.
• If retrieval of an access token fails, reattempt the procedure in 60 seconds. Otherwise, an intermittent error in network could result in an recoverable error.
• Speech input is considered complete only when an interim result uniquely matches one of the phrases in the used speech context.
• All the internal common class names are declared under a unique namespace not to cause a conflict with other speech recognition plugins being loaded in to the same instance of UniMRCP server.
• In case of DTMF input, allow both 'maxlength' and 'term char' be specified at the same time. Before, 'malxength' was not observed, if 'term char' was specified.

Configuration Parameters

• Added a new attribute 'language' to individual speech contexts.

Miscellaneous

• Fixed the digit format output in a log statement 'Detected Start of Event'.
• Updated the Usage Guide to reflect the changes introduced in this release.
