singleUtterance property

  1. @TagNumber(2)
bool get singleUtterance

If false or omitted, the recognizer will perform continuous recognition (continuing to wait for and process audio even if the user pauses speaking) until the client closes the input stream (gRPC API) or until the maximum time limit has been reached. May return multiple StreamingRecognitionResults with the is_final flag set to true.

If true, the recognizer will detect a single spoken utterance. When it detects that the user has paused or stopped speaking, it will return an END_OF_SINGLE_UTTERANCE event and cease recognition. It will return no more than one StreamingRecognitionResult with the is_final flag set to true.

The single_utterance field can only be used with specified models, otherwise an error is thrown. The model field in `RecognitionConfig` must be set to:

  • command_and_search
  • phone_call AND additional field useEnhanced=true
  • The model field is left undefined. In this case the API auto-selects a model based on any other parameters that you set in RecognitionConfig.

Implementation

@$pb.TagNumber(2)
$core.bool get singleUtterance => $_getBF(1);
  1. @TagNumber(2)
set singleUtterance (bool v)

Implementation

@$pb.TagNumber(2)
set singleUtterance($core.bool v) {
  $_setBool(1, v);
}
