PhraseSet.Types.Phrase

A Phrase contains words and phrase "hints" so that the speech recognition is more likely to recognize them. This can be used to improve the accuracy for specific words and phrases, for example, if specific commands are typically spoken by the user.

StreamingRecognizeRequest

Request message for the [StreamingRecognize][google.cloud.speech.v2.Speech.StreamingRecognize] method. Multiple [StreamingRecognizeRequest][google.cloud.speech.v2.StreamingRecognizeRequest] messages are sent in one call.

If the [Recognizer][google.cloud.speech.v2.Recognizer] referenced by [recognizer][google.cloud.speech.v2.StreamingRecognizeRequest.recognizer] contains a fully specified request configuration then the stream may only contain messages with only [audio][google.cloud.speech.v2.StreamingRecognizeRequest.audio] set.

Otherwise the first message must contain a [recognizer][google.cloud.speech.v2.StreamingRecognizeRequest.recognizer] and a [streaming_config][google.cloud.speech.v2.StreamingRecognizeRequest.streaming_config] message that together fully specify the request configuration and must not contain [audio][google.cloud.speech.v2.StreamingRecognizeRequest.audio]. All subsequent messages must only have [audio][google.cloud.speech.v2.StreamingRecognizeRequest.audio] set.

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:

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

StreamingRecognizeResponse.Types

Container for nested types declared in the StreamingRecognizeResponse message type.

TranscriptNormalization

Transcription normalization configuration. Use transcription normalization to automatically replace parts of the transcript with phrases of your choosing. For StreamingRecognize, this normalization only applies to stable partial transcripts (stability > 0.8) and final transcripts.
