Struct SpeakProfileId
sealed struct SpeakProfileId
SpeakProfileId is a struct that holds the identifiers of a Speak Profile.
A Speak Profile represents a predefined configuration for speech synthesis
that is optimized for a particular use case scenario. Each profile identifier
uniquely identifies a different scenario.
Common profile identifiers like DEFAULT, ACCESSIBILITY, and NAVIGATION
are set by the OEM to cover typical use cases. However, the complete
list of profiles and their meanings can vary between different products
and devices.
