Class StreamingRecognitionResult (4.5.11)

public final class StreamingRecognitionResult extends GeneratedMessageV3 implements StreamingRecognitionResultOrBuilder

Contains a speech recognition result corresponding to a portion of the audio that is currently being processed or an indication that this is the end of the single requested utterance. While end-user audio is being processed, Dialogflow sends a series of results. Each result may contain a transcript value. A transcript represents a portion of the utterance. While the recognizer is processing audio, transcript values may be interim values or finalized values. Once a transcript is finalized, the is_final value is set to true and processing continues for the next transcript. If StreamingDetectIntentRequest.query_input.audio_config.single_utterance was true, and the recognizer has completed processing audio, the message_type value is set to END_OF_SINGLE_UTTERANCE and the following (last) result contains the last finalized transcript. The complete end-user utterance is determined by concatenating the finalized transcript values received for the series of results. In the following example, single utterance is enabled. In the case where single utterance is not enabled, result 7 would not occur.

Concatenating the finalized transcripts with is_final` set to true, the complete utterance becomes "to be or not to be that is the question".

getConfidence()

public float getConfidence()

The Speech confidence between 0.0 and 1.0 for the current portion of audio. A higher number indicates an estimated greater likelihood that the recognized words are correct. The default of 0.0 is a sentinel value indicating that confidence was not set. This field is typically only provided if is_final is true and you should not rely on it being accurate or even set.

float confidence = 4;

Returns
TypeDescription
float

The confidence.
