Remarks
In its simplest form, text-to-speech can be done with just two classes:
var ss = new AVSpeechSynthesizer();
var su = new AVSpeechUtterance("Microphone check. One, two, one two.") {
Rate = AVSpeechUtterance.DefaultSpeechRate
};
ss.SpeakUtterance(su);
The Rate property specifies the speed with which the utterance is said. The rate does not appear to be processor-dependent and a rate of 1.0f is unnatural.
Constructors
| AVSpeechUtterance() |
Creates a new AVSpeechUtterance with default values. |
| AVSpeechUtterance(NativeHandle) |
A constructor used when creating managed representations of unmanaged objects. Called by the runtime. |
| AVSpeechUtterance(NSAttributedString) | |
| AVSpeechUtterance(NSCoder) |
A constructor that initializes the object from the data stored in the unarchiver object. |
| AVSpeechUtterance(NSObjectFlag) |
Constructor to call on derived classes to skip initialization and merely allocate the object. |
| AVSpeechUtterance(String, AVSpeechUtteranceInitializationOption) |
Create a new AVSpeechUtterance instance for the specified string. |
| AVSpeechUtterance(String) |
Create a new AVSpeechUtterance instance for the specified string. |
