Properties
desiredEventTypes ↔ List <String ?
The TTS event types that you are interested in listening to. If missing,
all event types may be sent.
getter/setter pair
enqueue ↔ bool ?
If true, enqueues this utterance if TTS is already in progress. If false
(the default), interrupts any current speech and flushes the speech queue
before speaking this new utterance.
getter/setter pair
extensionId ↔ String ?
The extension ID of the speech engine to use, if known.
getter/setter pair
gender ↔ VoiceGender ?
Gender of voice for synthesized speech.
getter/setter pair
hashCode → int
The hash code for this object.
no setter inherited
lang ↔ String ?
The language to be used for synthesis, in the form language -region .
Examples: 'en', 'en-US', 'en-GB', 'zh-CN'.
getter/setter pair
onEvent ↔ JSFunction ?
This function is called with events that occur in the process of speaking
the utterance.
getter/setter pair
pitch ↔ double ?
Speaking pitch between 0 and 2 inclusive, with 0 being lowest and 2 being
highest. 1.0 corresponds to a voice's default pitch.
getter/setter pair
rate ↔ double ?
Speaking rate relative to the default rate for this voice. 1.0 is the
default rate, normally around 180 to 220 words per minute. 2.0 is twice as
fast, and 0.5 is half as fast. Values below 0.1 or above 10.0 are strictly
disallowed, but many voices will constrain the minimum and maximum rates
further-for example a particular voice may not actually speak faster than
3 times normal even if you specify a value larger than 3.0.
getter/setter pair
requiredEventTypes ↔ List <String ?
The TTS event types the voice must support.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setter inherited
toJS → TtsOptions
no setter
voiceName ↔ String ?
The name of the voice to use for synthesis. If empty, uses any available
voice.
getter/setter pair
volume ↔ double ?
Speaking volume between 0 and 1 inclusive, with 0 being lowest and 1 being
highest, with a default of 1.0.
getter/setter pair
