type RecognitionConfig_AudioEncoding 

type RecognitionConfig_AudioEncoding int32

Audio encoding of the data sent in the audio message. All encodings support only 1 channel (mono) audio. Only `FLAC` includes a header that describes the bytes of audio that follow the header. The other encodings are raw audio bytes with no header.

For best results, the audio source should be captured and transmitted using a lossless encoding (`FLAC` or `LINEAR16`). Recognition accuracy may be reduced if lossy codecs (such as AMR, AMR_WB and MULAW) are used to capture or transmit the audio, particularly if background noise is present.

}

`StreamingRecognizeResponse` is the only message returned to the client by `StreamingRecognize`. A series of one or more `StreamingRecognizeResponse` messages are streamed back to the client.

Here's an example of a series of ten `StreamingRecognizeResponse`s that might be returned while processing audio:

1. endpointer_type: START_OF_SPEECH

  1. results { alternatives { transcript: "tube" } stability: 0.01 } result_index: 0
  1. results { alternatives { transcript: "to be a" } stability: 0.01 } result_index: 0
  1. results { alternatives { transcript: "to be" } stability: 0.9 } results { alternatives { transcript: " or not to be" } stability: 0.01 } result_index: 0
  1. results { alternatives { transcript: "to be or not to be" confidence: 0.92 } alternatives { transcript: "to bee or not to bee" } is_final: true } result_index: 0
  1. results { alternatives { transcript: " that's" } stability: 0.01 } result_index: 1
  1. results { alternatives { transcript: " that is" } stability: 0.9 } results { alternatives { transcript: " the question" } stability: 0.01 } result_index: 1

8. endpointer_type: END_OF_SPEECH

  1. results { alternatives { transcript: " that is the question" confidence: 0.98 } alternatives { transcript: " that was the question" } is_final: true } result_index: 1

10. endpointer_type: END_OF_AUDIO

Notes:

  • Only two of the above responses #5 and #9 contain final results, they are indicated by `is_final: true`. Concatenating these together generates the full transcript: "to be or not to be that is the question".
  • The others contain interim `results`. #4 and #7 contain two interim `results`, the first portion has a high stability and is less likely to change, the second portion has a low stability and is very likely to change. A UI designer might choose to show only high stability `results`.
  • The specific `stability` and `confidence` values shown above are only for illustrative purposes. Actual values may vary.
  • The `result_index` indicates the portion of audio that has had final results returned, and is no longer being processed. For example, the `results` in #6 and later correspond to the portion of audio after "to be or not to be".

	// detected, will send another START_OF_SPEECH event.

	// This event is sent after the client has half-closed the input stream gRPC

	// results.)
	StreamingRecognizeResponse_END_OF_AUDIO StreamingRecognizeResponse_EndpointerType = 3
	// This event is only sent when `single_utterance` is `true`. It 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.
