Google Dialogflow (GDF) Plugin 1.4.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

• UniMRCP Server 1.5.0
• Google Dialogflow API v2
• gRPC 1.7.3
• Protobuf 3.4.0

The binaries are currently available for the following Linux distributions:

• Red Hat / CentOS 7
• Ubuntu 16.04 LTS

This release adds support for the optional Dialogflow QueryParameters, which can be set via individual name/value tokens in the MRCP header field Vendor-Specific-Parameters.

The release provides an alternate way for start of input detection, derived from a first interim result. This behavior is configurable via a new parameter 'start-of-input'. The parameter can be set either to 'service-originated', which is the new and default behavior, or to 'internal', which is the old behavior, based on internal speech activity detector.

Also, when both the speech and DTMF detectors are activated, the DTMF detector remains active until a first interim result of speech transcription becomes available. In order to achieve this behavior, the new configuration parameter 'start-of-input' must be set to 'service-originated'.
