StreamingRecognizeResponse class

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:

  • 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.

Properties

eventPlugin → EventPlugin?
Subclasses can override this getter to be notified of changes to protobuf fields.
no setterinherited
hashCode int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setteroverride
isFrozen bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
metadata RecognitionResponseMetadata
Metadata about the recognition.
getter/setter pair
results List<StreamingRecognitionResult>
This repeated list contains zero or more results that correspond to consecutive portions of the audio currently being processed. It contains zero or one google.cloud.speech.v2.StreamingRecognitionResult.is_final=true result (the newly settled portion), followed by zero or more google.cloud.speech.v2.StreamingRecognitionResult.is_final=false results (the interim results).
no setter
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
speechEventOffset Duration
Time offset between the beginning of the audio and event emission.
getter/setter pair
speechEventType StreamingRecognizeResponse_SpeechEventType
Indicates the type of speech event.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
