3 Agenda Overview Developed Trials (our prototype) Arquitecture of Voice Internet Application Server Side Technologies and XML VoiceXML VoiceXML and our tests Conclusions

4 Overview Main concepts related to accessing the internet contents by speech via a telephone

5 OverView (cont) Financial, Banking Parking Pharmacies Hospitals Weather Entertainment Reservation, Billing, Others Reservation, Billing, Others

6 Overview (cont)

7 Developed trials Our prototype presents weather information of some european cities The > information is available via a normal telephone Phone number (34) ID: Pin: 1234

8 Developed Trials (cont.) Web Server:Apache Server Side Scripting Technology: PHP/Xalan Voice Markup Language: VoiceXML

9 Developed Trials (cont.)

10 Developed trials (cont.)

11 Arquitecture of Voice Internet Application

12 Arquitecture of Voice Internet Application (cont.)

13 Server Side Technologies and XML

14 Server Side Technologies and XML (cont.)

16 VoiceXML is designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed-initiative conversations W3C Consortium (Voice Extensible Markup Language, VoiceXML Version 2.0) VoiceXML is designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed-initiative conversations W3C Consortium (Voice Extensible Markup Language, VoiceXML Version 2.0) VoiceXML

17 VoiceXML is only used to describe the conversation between the voice portal and the caller (the user interface of the voice application) VoiceXML is only used to describe the conversation between the voice portal and the caller (the user interface of the voice application) VoiceXML (cont.)

18 VoiceXML and our tests Our prototype presents weather information of some european cities The > information is available via a normal telephone Phone number (34)

19 VoiceXML and our tests (cont.) Welcome to the European meteorological information service.

20 VoiceXML and our tests (cont.) Meteo.vxml

21 VoiceXML and our tests (cont.) Please select the city: Paris, Rome, London or Madrid. [paris rome london madrid] please choose one of the following cities: Paris, Rome, London or Madrid please say Paris, Rome, London or Madrid

22 VoiceXML and our tests (cont.)

23 Conclusions ABC#$% In this article a process to carry out a voice interaction with an application that generates dynamic content based on VoiceXML, has been described. With this structure, it is possible to access the server contents from a telephone, both fixed and mobile

24 Conclusions (cont.) ABC The voice portals inherit the advantages and disadvantages of technologies like the voice synthesis and voice recognition. The quality of the recognition, the background noise and the difficulty to maintainance of user's attention of must be considered with special attention.

25 Conclusions (cont.) ABC Also in the process of text-to-speech conversion it is important to simulate human-to-human conversation as best as possible.

26 Conclusions (cont.) xxx ABC It has been possible to identify different lines of research such as the development of platforms for the detection of different accents, multilingual applications, natural language processing integrated in voice portals and the development of systems to integrates voice speech with other devices in multimodal applications.

27 The end…. Thank you! Colombia-Spain Eduardo Carrillo: Tel: +(34)
