Google Cloud Speech v1p1beta1 API - Class StreamingRecognizeResponse (3.0.0-beta07)

Reference documentation and code samples for the Google Cloud Speech v1p1beta1 API 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, and single_utterance is set to false, then no messages are streamed back to the client.

Here's an example of a series 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:

• 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".

• 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.

• The specific stability and confidence values shown above are only for illustrative purposes. Actual values may vary.

• In each response, only one of these fields will be set: error, speech_event_type, or one or more (repeated) results.

If set, returns a [google.rpc.Status][google.rpc.Status] message that specifies the error for the operation.

The ID associated with the request. This is a unique ID specific only to the given request.

This repeated list contains zero or more results that correspond to consecutive portions of the audio currently being processed. It contains zero or one is_final=true result (the newly settled portion), followed by zero or more is_final=false results (the interim results).

Provides information on adaptation behavior in response

Time offset between the beginning of the audio and event emission.

Indicates the type of speech event.

When available, billed audio seconds for the stream. Set only if this is the last response in the stream.
