The SymBase5 platform is a speech dialogue system for call centers. It integrates the following modules:

• SymPBX establishes the connection to the telephone system and coordinates the communication between speech recognition, dialog manager and synthesis. Recognition engines are integrated using standardized interfaces. Besides the Sympalog speech recognizer SymRec, other commercial products can be used.
• SymDialog, the dialog manager, is the “intelligence” behind the system; it analyzes voice data input and generates a dynamic system response.
• SymTTS, the text-to-speech module, is responsible of converting the text-based system response into a voice signal using pre-recorded speech or third-party TTS components.
