Title: CHANGING THE NETWORK INTERFACE- VOICE,DATA, AND CUSTOMER

( )Author s : Koehn, Kraig W.Source: Proceedings of the 1997 IEE Colloquium on PrivateNetworks - Can They Compete? Jun 25 1997. n 158 London,UK. IEE Stevenage Engl p 5r1-5r3 ISSN: 0963-3308 CO-DEN: DCILDNPublication Year: 1997Abstract: With advances in digital telephony, much of thesimplicity that used to be associated with managing the voice,data and video requirements of an organization have changed.As a result, office managers, corporate telephony managersand information technology managers are faced with an in-creasingly complex array of choices, further confused by re-quirements for increased functionality from their internalcustomers. Many of these technologies have evolved and areoffered by various telecommunications providers in order toservice these requirements. The evolution of some of thesetechnologies and an illustration of the changes associated withthe selection and integration of these technologies to meet theexpanding end user needs are presented.

Title: VOICE IN VPNS - IS PUBLIC NETWORK TECH-NOLOGY UP TO THE TASK?

Ž .Abstract: In virtual private networks VPN , where the privateŽ .branch exchanges PBX are retained but the leased lines are

replaced by dynamically switched connections, the key issue issignaling. When it comes to the handling of voice, there is farmore to corporate networking than just picking up the phone,dialing a number and simply talking to someone. VPNs workby the public exchange software, supporting enough of theprivate network signaling system to be able to switch connec-tions on a call to call basis instead of simply cross-connecting2 Mbitrsec pipes that transport all traffic and signaling trans-parently. Essentially, the public network appears to the PBXsas a single large transit PBX.

Title: MULTIPLE MOBILE ROBOT INTERFACE USING ALOW COST VOICE RECOGNITION CHIP

( )Author s : Lim, Seung-Hyun; Jeon, Jae WookSource: Proceedings of the 1997 6th IEEE InternationalWorkshop on Robot and Human Communication, RO-MAN’97 Sep 29-Oct 1 1997 Sendai, Jpn. Sponsored by: IEEEPiscataway NJ USA. p 402-407 CODEN: 85QKA5Publication Year: 1997Abstract: Voice is one of convenient methods to communicatebetween human and robots. To command a lot of robot taskby voice, voices of the same number have to be able to berecognized. But the more the number of recognition voice is,the higher the cost of recognition system is and the longer thetime of recognition is. In this paper, a low cost voice recogni-tion system which can distinguish a lot of robot task is pro-posed. The proposed system consists of a general purposemicroprocessor and a low cost voice recognition processorwhich can recognize a limited number of voice patterns. Givenmultiple robots, each robot task is classified and organizedsuch that the number of robot tasks under each directory isnot more than the maximum recognition number of the voicerecognition processor so that robot tasks under each directorycan be distinguished by the voice recognition processor.

Title: ROBOT LISTENER FOR FLUENT VERBAL COMMU-NICATION

( )Author s : Yatsuka, Koichi; Kawabata, Kuniaki; Kobayashi,HisatoSource: Proceedings of the 1997 6th IEEE InternationalWorkshop on Robot and Human Communication, RO-MAN’97 Sep 29-Oct 1 1997 Sendai, Jpn. Sponsored by: IEEEPiscataway NJ USA. p 408-411 CODEN: 85QKA5Publication Year: 1997Abstract: This paper considers verbal communications betweenmachines and human beings. Speakers may have heavy psy-chological stress if the all listeners are not human being suchas computers and so on. Because human listeners assist thespeaker by nodding and chiming. Watanabe et al. showed thatsuch responses of listeners greatly assist fluent verbal commu-nications. On the base of this result, they proposed a com-puter listener system, animation in which can do nodding andchiming in place of human listeners. However, computer ani-mations in imaginary two dimensional space may have essen-tial psychological defect comparing with physical existing ob-jects in three dimensional space. This paper tries to makeclear this psychological difference quantitatively by severalexperiments. In the experiments, we adopt a doll as a listener,that have three degrees of freedom in its neck, and it can nodand chime in responding to the speakers words. We evaluatethe speaker’s psychological stress by heart rate, blood pressure
