SpeechEventType(value)Indicates the type of speech event.
Values:
SPEECH_EVENT_UNSPECIFIED (0):
No speech event specified.
END_OF_SINGLE_UTTERANCE (1):
This event indicates that the server has detected the end of
the user's speech utterance and expects no additional
speech. Therefore, the server will not process additional
audio (although it may subsequently return additional
results). The client should stop sending additional audio
data, half-close the gRPC connection, and wait for any
additional results until the server closes the gRPC
connection. This event is only sent if single_utterance
was set to true, and is not used otherwise.
SPEECH_ACTIVITY_BEGIN (2):
This event indicates that the server has detected the
beginning of human voice activity in the stream. This event
can be returned multiple times if speech starts and stops
repeatedly throughout the stream. This event is only sent if
voice_activity_events is set to true.
SPEECH_ACTIVITY_END (3):
This event indicates that the server has detected the end of
human voice activity in the stream. This event can be
returned multiple times if speech starts and stops
repeatedly throughout the stream. This event is only sent if
voice_activity_events is set to true.
SPEECH_ACTIVITY_TIMEOUT (4):
This event indicates that the user-set
timeout for speech activity begin or end has
exceeded. Upon receiving this event, the client
is expected to send a half close. Further audio
will not be processed.
