• Use a Player object to play prerecorded prompts in an interactive voice response (IVR) application.

• Use a Recorder object to record messages or conversations in a call.

• Use a ToneController object to receive or send DTMF commands and perform actions on these DTMF commands, or to send or receive Fax tones.

• Use a SpeechRecognitionConnector object, in conjunction with the Microsoft.Speech namespace, to perform speech recognition.

• Use a SpeechSynthesisConnector object, in conjunction with the Microsoft.Speech namespace, to render text as speech.
