VADResult class

Result of a single VAD pass over a chunk of PCM audio. Sources pre-IDL: Swift VADTypes.swift — (no struct; bool returned from detectSpeech()) Kotlin VADTypes.kt:152 (isSpeech, confidence, energyLevel, statistics, timestamp) Dart dart_bridge_vad.dart:290 (isSpeech, energy, speechProbability) RN VADTypes.ts:26 (isSpeech, probability, startTime, endTime) Web VADTypes.ts — (no VADResult; only SpeechSegment) C ABI rac_vad_types.h:151 (rac_vad_output_t) (is_speech_detected, energy_level, timestamp_ms)

Drift notes:

  • Kotlin's confidence and Dart's speechProbability and RN's probability collapse onto the canonical confidence field.
  • Kotlin/RN/C all carry timing — we encode duration_ms (length of the analyzed frame). Wall-clock timestamps belong on the carrying envelope (e.g. VoiceEvent.timestamp_us in voice_events.proto).
