Cloud Speech V2 Client - Class StreamingRecognizeResponse (1.19.1)

Reference documentation and code samples for the Cloud Speech V2 Client class StreamingRecognizeResponse.

StreamingRecognizeResponse is the only message returned to the client by StreamingRecognize. A series of zero or more StreamingRecognizeResponse messages are streamed back to the client. If there is no recognizable audio then no messages are streamed back to the client.

Here are some examples of StreamingRecognizeResponses that might be returned while processing audio:

  1. results { alternatives { transcript: "tube" } stability: 0.01 }
  2. results { alternatives { transcript: "to be a" } stability: 0.01 }
  3. results { alternatives { transcript: "to be" } stability: 0.9 } results { alternatives { transcript: " or not to be" } stability: 0.01 }
  4. results { alternatives { transcript: "to be or not to be" confidence: 0.92 } alternatives { transcript: "to bee or not to bee" } is_final: true }
  5. results { alternatives { transcript: " that's" } stability: 0.01 }
  6. results { alternatives { transcript: " that is" } stability: 0.9 } results { alternatives { transcript: " the question" } stability: 0.01 }
  7. results { alternatives { transcript: " that is the question" confidence: 0.98 } alternatives { transcript: " that was the question" } is_final: true } Notes:
  8. Only two of the above responses #4 and #7 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".
  9. The others contain interim results. #3 and #6 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.
  10. The specific stability and confidence values shown above are only for illustrative purposes. Actual values may vary.
  11. In each response, only one of these fields will be set: error, speech_event_type, or one or more (repeated) results.

↳ speech_event_offset Google\Protobuf\Duration

Time offset between the beginning of the audio and event emission.
↳ metadata RecognitionResponseMetadata

Metadata about the recognition.
