TTSSynthesisMetadata class

Synthesis metadata.

Mirrors the C ABI rac_tts_synthesis_metadata_t. Time units in milliseconds and durations as int64 to match the C ABI.

Available extensions

Constructors

TTSSynthesisMetadata.fromJson(String json, [ExtensionRegistry registry = $pb.ExtensionRegistry.EMPTY])

Properties

audioDurationMs ↔ Int64
Audio duration in milliseconds. Present in C ABI rac_tts_output_t but mirrored here so metadata is self-describing for clients that consume metadata-only paths (e.g. TTSSpeakResult).
getter/setter pair
characterCount ↔ int
Number of input characters synthesized.
getter/setter pair
charactersPerSecond ↔ double
Characters processed per second. Some native paths expose this directly; consumers may also compute it from character_count / processing_time_ms.
getter/setter pair
hashCode → int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setter
isFrozen → bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
languageCode ↔ String
Language used for synthesis (BCP-47). Source field name varies: C ABI: language, Swift: language, Kotlin: language. We use language_code to match TTSConfiguration / TTSOptions.
getter/setter pair
processingTimeMs ↔ Int64
Wall-clock processing time in milliseconds.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
unknownFields → UnknownFieldSet
no setterinherited
voiceId ↔ String
Voice id used for synthesis.
getter/setter pair
