public sealed class StreamingRecognizeRequest : IMessage<StreamingRecognizeRequest>, IEquatable<StreamingRecognizeRequest>, IDeepCloneable<StreamingRecognizeRequest>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud Speech-to-Text v2 API class StreamingRecognizeRequest.
Request message for the
[StreamingRecognize][google.cloud.speech.v2.Speech.StreamingRecognize]
method. Multiple
[StreamingRecognizeRequest][google.cloud.speech.v2.StreamingRecognizeRequest]
messages are sent in one call.
If the [Recognizer][google.cloud.speech.v2.Recognizer] referenced by
[recognizer][google.cloud.speech.v2.StreamingRecognizeRequest.recognizer]
contains a fully specified request configuration then the stream may only
contain messages with only
[audio][google.cloud.speech.v2.StreamingRecognizeRequest.audio] set.
Otherwise the first message must contain a
[recognizer][google.cloud.speech.v2.StreamingRecognizeRequest.recognizer] and
a
[streaming_config][google.cloud.speech.v2.StreamingRecognizeRequest.streaming_config]
message that together fully specify the request configuration and must not
contain [audio][google.cloud.speech.v2.StreamingRecognizeRequest.audio]. All
subsequent messages must only have
[audio][google.cloud.speech.v2.StreamingRecognizeRequest.audio] set.
Required. The name of the Recognizer to use during recognition. The
expected format is
projects/{project}/locations/{location}/recognizers/{recognizer}. The
{recognizer} segment may be set to _ to use an empty implicit Recognizer.
public StreamingRecognitionConfig StreamingConfig { get; set; }
StreamingRecognitionConfig to be used in this recognition attempt.
If provided, it will override the default RecognitionConfig stored in the
Recognizer.
