MediaPipeTasksAudio Framework Reference

Structures

The following declarations are available globally.

• AudioChunk

  Incremental mono PCM audio chunk emitted by TextToSpeech.synthesizeStream(_:options:).

  Declaration

  Swift

  struct AudioChunk: Sendable, Equatable

• AudioResult

  Self-contained mono PCM audio buffer returned by TextToSpeech.synthesize(_:options:).

  Declaration

  Swift

  struct AudioResult: Sendable, Equatable

• SynthesisOptions

  Per-utterance synthesis overrides passed to TextToSpeech.synthesize(_:options:) and TextToSpeech.synthesizeStream(_:options:). Both fields default to nil so non-English voices (e.g. "ef_dora", "zf_xiaobei") automatically infer their native language from the voice metadata.

  Declaration

  Swift

  struct SynthesisOptions: Sendable, Equatable

• TTSBaseOptions

  MediaPipe Tasks-harmonized base options for .litertlm model loading and hardware delegation.

  Declaration

  Swift

  struct TTSBaseOptions: Sendable, Equatable

• TextToSpeechOptions

  Task initialization options for TextToSpeech (backed by LiteRT-LM Omni Kokoro-82M).

  Declaration

  Swift

  struct TextToSpeechOptions: Sendable, Equatable

• VoiceInfo

  Voice metadata descriptor returned by TextToSpeech.listVoices().

  Declaration

  Swift

  struct VoiceInfo: Sendable, Equatable

• WordTimestamp

  Word-level timing alignment mapping an input word to audio seconds.

  Declaration

  Swift

  struct WordTimestamp: Sendable, Equatable
