Overview of Majordome • Background tasks (server-side only): • sorting and filtering messages from different sources (E-mail, voice, fax, SMS,…); • extracting relevant information for reporting to user (names of senders, subject,…). • Dialogue with the user: over phone or Web. • The system presents the state of the mailbox, the type of messages, their sender, subject, and may sum them up or read them on request; • The users access their mailbox, addressbook, time schedule, or URIs (Web addresses).
Voice technology in Majordome • Server side background tasks: continuous speech recognition applied to voice messages upon reception • Detection of sender’s name and subject • User interaction: • Identification of the speaker (and Verification if necessary) • Speech recognition (receiving users’ commands through voice interaction) • Text-to-speech synthesis (reading text summaries, E-mails or faxes)

Perspectives • Add Vision, Hearing and Understanding to Mobile Terminals (UMTS) • Multimedia for Distance Education and Conference Indexing • Semantic Web, • ‘Universal Networking Language’ • ‘Smart Home’, ‘Smart Car’, ‘Smart Office’
Perspectives • The application context of the Majordome project could be of interest to COST-278. • The Majordome/NetCentrex platform could be made available to interested partners. • HTK, ISIP and SIROCCO softwares are available as freeware. One of them will be used on the NetCentrex platform.
