Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SsmlMark

Fields

at_millis: f32

The position in milliseconds the mark occurred, relative to the beginning of the audio stream.

mark: Box<str>

The name of the mark in SSML.

Marks the audio offset of an SSML <mark />.

WordBoundary

Fields

from_millis: f32

The position in milliseconds the spoken word begun, relative to the beginning of the audio stream.

to_millis: f32

The position in milliseconds the spoken word ended, relative to the beginning of the audio stream.

text: Box<str>

The text of the single word spoken between this boundary.

Marks the time boundary of a spoken word in the audio.

SentenceBoundary

Fields

from_millis: f32

The position in milliseconds the sentence begun, relative to the beginning of the audio stream.

to_millis: f32

The position in milliseconds the sentence ended, relative to the beginning of the audio stream.

text: Box<str>

The text of the sentence spoken between this boundary.

Marks the time boundary of a sentence in the audio.

BlendShapeVisemesChunk(Box<[BlendShapeVisemeFrame]>)

A chunk of viseme frames in blend shape format.

VisemesChunk(Box<[BasicVisemeFrame]>)

A chunk of frames of ‘basic’ visemes.

AudioChunk(Box<[u8]>)

A chunk of synthesised speech audio in the requested format.
