Remarks

A SpeechSequentialWorkflowActivity is the basic building block that speech authors use to develop speech applications that use workflows. A SpeechSequentialWorkflowActivity instance provides access to the application host (ApplicationHost), to recognizers (DtmfRecognizer and SpeechRecognizer), to the synthesizer (Synthesizer), to a recorder (Recorder), and to the telephony session (TelephonySession).
