TTSOutput class


Full TTS output: synthesized audio plus metadata.

Mirrors the C ABI rac_tts_output_t. audio_data is opaque bytes; bindings adapt to native buffers (Swift Data, Kotlin ByteArray, Dart Uint8List, JS ArrayBuffer/Float32Array, C void*). Sample rate is required because PCM payloads are otherwise unparseable.

Properties

audioData List<int>
Synthesized audio bytes, encoded per audio_format.
getter/setter pair
audioFormat AudioFormat
Audio format of the bytes in audio_data.
getter/setter pair
audioSizeBytes ↔ Int64
getter/setter pair
chunkIndex int
Stream chunk metadata. For one-shot synthesis, chunk_index=0 and is_final=true when set by the producer.
getter/setter pair
durationMs ↔ Int64
Audio duration in milliseconds (matches C ABI duration_ms).
getter/setter pair
errorCode int
getter/setter pair
errorMessage String
Terminal error details for result-envelope APIs.
getter/setter pair
hashCode int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setter
isFinal bool
getter/setter pair
isFrozen bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
metadata TTSSynthesisMetadata
Per-pass synthesis metadata.
getter/setter pair
phonemeTimestamps → PbList<TTSPhonemeTimestamp>
Phoneme-level timestamps, if the engine produced them. May be empty.
no setter
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
sampleRate int
Sample rate in Hz. For PCM payloads this is required to interpret the bytes; for compressed formats (mp3, opus, …) it reflects the synthesis sample rate, not the container rate.
getter/setter pair
timestampMs ↔ Int64
Wall-clock timestamp when the output was produced (milliseconds since UNIX epoch). Mirrors C ABI timestamp_ms.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
