Initializes a new instance of the SpeechSynthesizer class.
Assembly: System.Speech (in System.Speech.dll)
When you initialize a new SpeechSynthesizer instance, it uses the default system voice. To configure the SpeechSynthesizer to use one of the installed speech synthesis (text-to-speech) voices, use the SelectVoice or SelectVoiceByHints method. To get information about which voices are installed, use the GetInstalledVoices method and the VoiceInfo class.
