Overview

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.

Example:

  1. transcript: "tube"

  2. transcript: "to be a"

  3. transcript: "to be"

  4. transcript: "to be or not to be" is_final: true

  5. transcript: " that's"

  6. transcript: " that is"

  7. recognition_event_type: RECOGNITION_EVENT_END_OF_SINGLE_UTTERANCE

  8. transcript: " that is the question" is_final: true

Only two of the responses contain final results (#4 and #8 indicated by is_final: true). Concatenating these generates the full transcript: "to be or not to be that is the question".

In each response we populate:

  • for MESSAGE_TYPE_TRANSCRIPT: transcript and possibly is_final.

  • for MESSAGE_TYPE_END_OF_SINGLE_UTTERANCE: only event_type.

Instance Attribute Details

#confidence ⇒ Float

Returns 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.

Returns:

  • (Float) —

    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.

#is_final ⇒ true, false

Returns The default of 0.0 is a sentinel value indicating confidence was not set. If false, the StreamingRecognitionResult represents an interim result that may change. If true, the recognizer will not return any further hypotheses about this piece of the audio. May only be populated for event_type = RECOGNITION_EVENT_TRANSCRIPT.
