Configure The SpeechSynthesizer class provides access to the
functionality of a speech synthesis engine that is installed on
the host computer. Installed speech synthesis engines are
represented by a voice, for example Microsoft Anna. A
SpeechSynthesizer instance initializes to the default voice. To
configure a SpeechSynthesizer instance to use one of the other
installed voices, call the SelectVoice or SelectVoiceByHints

the SpeechSynthesizer to a stream, a file, the default audio
device, or to a null device by using one of the methods in the
SpeechSynthesizer class whose name begins with “SetOutputTo”.
