Declaration

class SFTranscriptionSegment

Overview

Use SFTranscriptionSegment to get details about a part of an overall SFTranscription. An SFTranscriptionSegment represents an utterance, which is a vocalized word or group of words that represent a single meaning to the speech recognizer (SFSpeechRecognizer).

You don’t create transcription object segments directly. Instead, you access them from a transcription’s segments property.

A transcription segment includes the following information:

  • The text of the utterance, plus any alternative interpretations of the spoken word.

  • The character range of the segment within the formattedString of its parent SFTranscription.

  • A confidence value, indicating how likely it is that the specified string matches the audible speech.

  • A timestamp and duration value, indicating the position of the segment within the provided audio stream.
