MessageType(value)Type of the response message.
Values:
MESSAGE_TYPE_UNSPECIFIED (0):
Not specified. Should never be used.
TRANSCRIPT (1):
Message contains a (possibly partial)
transcript.
DTMF_DIGITS (3):
Message contains DTMF digits. When the client
gets the message, it should stop sending
additional data, half-close the gRPC connection,
and wait for any additional results until the
server closes the gRPC. connection.
END_OF_SINGLE_UTTERANCE (2):
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
message is only sent if single_utterance was set to
true, and is not used otherwise.
PARTIAL_DTMF_DIGITS (4):
Message contains DTMF digits. Before a message with
DTMF_DIGITS is sent, a message with PARTIAL_DTMF_DIGITS may
be sent with DTMF digits collected up to the time of
sending, which represents an intermediate result.
