Speech Server implements and exposes the Speech Server API, which covers the core areas needed to produce speech-enabled telephony applications:

  • Speech synthesis ??? When the application prompts the caller for information or simply provides the caller with information, the prompt is handled through the Synthesizer property.
  • Speech recognition ??? When a caller responds to a prompt, the recognition is handled through the SpeechRecognizer property.
  • Call handling and control ??? The TelephonySession property provides methods for call control, such as answering or transferring a call.
  • DTMF processing ??? When a caller presses a keypad button (DTMF input), the application processes it through the DtmfRecognizer property.
  • Application hosting ??? With the IApplicationHost and IHostedSpeechApplication interfaces, Speech Server manages the lifetime of an application instance.
