4. Voice-based generic UPnP Control Point Andreas Bobek Slide 3 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering 1. What is UPnP / 2. What is an UPnP Control Point? -UPnP = Universal Plug and Play -supports ad-hoc networking of devices and services -only protocols are defined (UDP, TCP, SOAP, SSDP, GENA, HTTP) -independent of programming language, operating system and transmission medium -six phases: addressing, discovery, description, control, eventing, and presentation -defines three communicating components: device, service, control point

5. Voice-based generic UPnP Control Point Andreas Bobek Slide 4 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering -role: server -offers services -may contain other devices -“root device” -characterized by properties such as model number, model name, vendor... -uniquely identifiable by UUID -interface to the device -offers actions and URLs for controlling, eventing, and presentation -manages its state in state variables 1. What is UPnP / 2. What is an UPnP Control Point?

6. Voice-based generic UPnP Control Point Andreas Bobek Slide 5 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering -role: client -searches for devices and/or services -invokes actions (at services) -requests state variables 1.

9. Voice-based generic UPnP Control Point Andreas Bobek Slide 7 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering 3. What is a generic UPnP Control Point? -Device-specific Control Point -tailored to special purposes (comfortable user interface is possible) -usable with according device type only (TV remote control => TV, heating control => heater) -Generic Control Point -each UPnP Device is controllable -less comfortable than specific Control Points Device-specific Control Point vs. Generic Control Point

11. Voice-based generic UPnP Control Point Andreas Bobek Slide 9 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering 4. How can we make a generic Control Point voice-based? what we need: -speech recognition (Speech Recognition Engine) -synthesizing of speech (Text-to-Speech Engine) what we can use: -VoiceAPI which implements both engines -VoiceXML Browser which contains the VoiceAPI

12. Voice-based generic UPnP Control Point Andreas Bobek Slide 10 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering 4. How can we make a generic Control Point voice-based? VoiceAPI VoiceAPI consists of: -Speech Recognition Engine (for speech recognition) -Text-to-Speech Engine (for synthesizing speech) -Voice Recorder (to record audio data) -Audio Player (to play back existing audio data)

15. Voice-based generic UPnP Control Point Andreas Bobek Slide 13 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering 4. How can we make a generic Control Point voice-based? Coupled Architecture -Communication between all components is based on programming language specific messages. -Application has direct access to VoiceAPI. -VoiceAPI recognizes spoken words and notifies the application. -Application uses VoiceAPI for speech synthesis. -for local networks only

16. Voice-based generic UPnP Control Point Andreas Bobek Slide 14 of 21 University of Rostock Faculty of Computer Science and Electrical Engineering 4. How can we make a generic Control Point voice-based? Decoupled Architecture -Communication between voice component is based on request-response cycles using VoiceXML over HTTP. -Every communication process has to be initiated by the VoiceXML browser (client). -Control in local and remote networks is possible (e.g. remote control of house or car).
