Method Detail

getTranscript

public String getTranscript()

Gets the transcript.

A transcription of the audio.

Returns:

the transcript

getConfidence

public Double getConfidence()

Gets the confidence.

A score that indicates the service's confidence in the transcript in the range of 0.0 to 1.0. For speech recognition with previous-generation models, a confidence score is returned only for the best alternative and only with results marked as final. For speech recognition with next-generation models, a confidence score is never returned.

Returns:

the confidence

getTimestamps

public List<SpeechTimestamp> getTimestamps()

Gets the timestamps.

Time alignments for each word from the transcript as a list of lists. Each inner list consists of three elements: the word followed by its start and end time in seconds, for example: `[["hello",0.0,1.2],["world",1.2,2.5]]`. Timestamps are returned only for the best alternative.

Returns:

the timestamps

getWordConfidence

public List<SpeechWordConfidence> getWordConfidence()

Gets the wordConfidence.

A confidence score for each word of the transcript as a list of lists. Each inner list consists of two elements: the word and its confidence score in the range of 0.0 to 1.0, for example: `[["hello",0.95],["world",0.866]]`. Confidence scores are returned only for the best alternative and only with results marked as final.

Returns:

the wordConfidence
