Adaptive Multi-Rate Narrowband codec.

Adaptive Multi-Rate Wideband codec.

Not specified.

This is the recommended encoding for `SyncRecognize` and `StreamingRecognize` because it uses lossless compression; therefore recognition accuracy is not compromised by a lossy codec.

Uncompressed 16-bit signed little-endian samples (Linear PCM).

8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.

This event is sent after the client has half-closed the input stream gRPC connection and the server has received all of the audio.

Speech has ceased to be detected in the audio stream.

This event is only sent when `single_utterance` is `true`.

No endpointer event specified.

Speech has been detected in the audio stream, and the service is beginning to process it.

Describes the progress of a long-running `AsyncRecognize` call.

The top-level message sent by the client for the `AsyncRecognize` method.

The only message returned to the client by `AsyncRecognize`.

Contains audio data in the encoding specified in the `RecognitionConfig`.

Provides information to the recognizer that specifies how to process the request.

Provides "hints" to the speech recognizer to favor specific words and phrases in the results.

Alternative hypotheses (a.k.a.

A speech recognition result corresponding to a portion of the audio.

Provides information to the recognizer that specifies how to process the request.

A streaming speech recognition result corresponding to a portion of the audio that is currently being processed.

The top-level message sent by the client for the `StreamingRecognize` method.

`StreamingRecognizeResponse` is the only message returned to the client by `StreamingRecognize`.

The top-level message sent by the client for the `SyncRecognize` method.

The only message returned to the client by `SyncRecognize`.

Audio encoding of the data sent in the audio message.

Indicates the type of endpointer event.
