Struct VadSyncDetector

pub struct VadSyncDetector { /* private fields */ }

VAD-based subtitle synchronization detector.

Uses Voice Activity Detection to analyze audio files and calculate subtitle timing offsets by comparing detected speech segments with subtitle timing information.

Implementations

impl VadSyncDetector

pub fn new(config: VadConfig) -> Result<Self>

Create a new VAD sync detector.

Arguments

• config - VAD configuration parameters

Returns

A new VadSyncDetector instance

Errors

Returns an error if the VAD detector cannot be initialized

pub async fn detect_sync_offset( &self, audio_path: &Path, subtitle: &Subtitle, _analysis_window_seconds: u32, ) -> Result<SyncResult>

Detect synchronization offset between audio and subtitle.

Analyzes the entire audio file using VAD to identify speech segments and compares them with subtitle timing to calculate the offset.

Arguments

• audio_path - Path to the audio file to analyze
• subtitle - Subtitle data with timing information
• _analysis_window_seconds - Ignored parameter (processes entire file)

Returns

Synchronization result with detected offset and confidence

Errors

Returns an error if:

• Audio analysis fails
• Subtitle has no entries
• VAD processing fails
