Struct PiperEncoder 

pub struct PiperEncoder { /* private fields */ }

High-level encoder that converts IPA token sequences into Piper-compatible phoneme ID arrays with BOS/EOS/PAD insertion.

Implementations

impl PiperEncoder

pub fn new( id_map: PhonemeIdMap, mode: UnknownTokenMode, ) -> Result<Self, G2pError>

Create a new encoder from a phoneme ID map.

pub fn encode(&self, tokens: &[String]) -> Result<Vec<i64>, G2pError>

Encode IPA tokens to phoneme IDs with BOS/EOS/PAD insertion.

pub fn encode_with_eos( &self, tokens: &[String], eos_token: Option<&str>, ) -> Result<Vec<i64>, G2pError>

Encode IPA tokens with a custom EOS token.

• eos_token = None → default EOS ("$")
• eos_token = Some("?") → look up "?" in id_map
• eos_token = Some("?!") → look up PUA-mapped "?!" in id_map

pub fn encode_with_prosody( &self, tokens: &[String], prosody: &[Option<ProsodyInfo>], ) -> Result<(Vec<i64>, Vec<ProsodyFeature>), G2pError>

Encode IPA tokens with prosody alignment.

pub fn encode_with_prosody_and_eos( &self, tokens: &[String], prosody: &[Option<ProsodyInfo>], eos_token: Option<&str>, ) -> Result<(Vec<i64>, Vec<ProsodyFeature>), G2pError>

Encode IPA tokens with prosody alignment and a custom EOS token.
