Struct LipSyncTrack 

pub struct LipSyncTrack {
    pub events: Vec<PhonemeEvent>,
    pub duration: f32,
}

A complete lip-sync track: an ordered sequence of PhonemeEvents.

Fields

events: Vec<PhonemeEvent>

Phoneme events sorted by start time.

duration: f32

Total duration of the track in seconds.

Implementations

impl LipSyncTrack

pub fn new() -> Self

Create an empty track.

pub fn add_event(&mut self, event: PhonemeEvent)

Append a phoneme event, updating duration as needed.

pub fn event_count(&self) -> usize

Number of events in the track.

pub fn evaluate(&self, t: f32, mapper: &VisemeMapper) -> VisemeMorphWeights

Evaluate morph weights at time t.

Finds the active event (start ≤ t < end) and applies a short coarticulation blend: in the last 0.05 s of an event the weights are linearly interpolated toward the next event’s weights.

pub fn from_string(s: &str) -> Self

Parse a simple phoneme timeline string.

Format: "0.0:AA 0.2:B 0.4:IY"

Each token is <start>:<PHONEME>. The duration of each event is inferred as the gap to the next token, or 0.1 s for the last token.

Trait Implementations

impl Default for LipSyncTrack

fn default() -> Self

Returns the “default value” for a type.
