rate property
double?
get
rate
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.
Implementation
double? get rate => _wrapped.rate;
set
rate
(double? v)
Implementation
set rate(double? v) {
_wrapped.rate = v;
