Struct Synthesis 

pub struct Synthesis<T> { /* private fields */ }

Available on non-target_family=wasm only.

A loaded synthesis engine ready to start utterances.

Implementations

impl<T> Synthesis<T>

pub fn new(engine: T) -> Self

impl<T: Engine> Synthesis<T>

pub fn start(&self, text: &SpeechText) -> Result<Session, SynthesisError>

Starts an utterance with the engine’s default voice and natural pace.

pub fn start_with( &self, text: &SpeechText, voice: Option<&Voice>, rate: SpeakingRate, cancel: &CancelToken, ) -> Result<Session, SynthesisError>

Starts an utterance and returns its PCM as it is produced.

An engine that owns playback cannot provide a PCM session. Use Synthesis::speak_with for that engine instead.

impl<T: Engine> Synthesis<T>

pub fn speak(&self, text: &SpeechText) -> Result<(), SynthesisError>

Available on crate feature playback only.

Speaks with the engine’s default voice at its natural pace and waits until the utterance has been heard.

pub fn speak_with( &self, text: &SpeechText, voice: Option<&Voice>, rate: SpeakingRate, cancel: &CancelToken, ) -> Result<(), SynthesisError>

Available on crate feature playback only.

Speaks one utterance and waits until it has been heard.
