This paper describes the implementation of a system that reminds the user of the telephone number of a given list, even if the user only remembers part of it, or if the given number contains a series of exchanged digits. The system’s input consists of a telephone number (composed by digits from 0 to 9), containing from zero up to several generic digits (asterisks, in this case). The system proc...

In the decade, the video phones have brought the intense interests for its service. However, the limited network bandwidth, the unfriendly operations like IP dialing, and the dynamic host configuration protocol, DHCP, environment bound the development. An innovative video phone system, IVPS, based on a creative data transmission architecture has been presented in the paper, especially the advan...

Recognition of spelled names over the telephone line is essential for applications such as telephone directory assistance, or automatic mail ordering. We present recognition results on the spelling section of the OGI Spelled and Spoken Word Telephone Corpus, using a Multi-State Time Delay Neural Network (MS-TDNN). Many applications allow for strong language modeling constraints. In our experime...

Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in speech waves. This technique makes it possible to use the speaker’s voice to verify their identity and control access to services such as voice dialing, banking by telephone, telephone shopping, database access services, information services, voice mail, security co...

This paper studies searching and pruning process of the telephone speech recognition system for Private Automatic Branch Exchange (PABX) to explore the possible problems encountered in applying speech recognition to telephone network and to prepare the necessary techniques for the practical telephone speech recognition systems. Experiment on a baseline system which uses semi-syllable based mult...

An admission control based QoS scheme for IP networks which extends the telephone network’s QoS model is proposed in this paper. The basic call admission employed in telephone network is the Erlang-B model. It derives the traffic-QoS relationship through network capacity, its current utilization and future traffic demand. The same principle is been remodeled here to suit the IP network. It is u...

background: various strategies such as teaching self care to hemodialysis patients have been employed to increase the level of their hope. this study aimed at examining the effects of a telephone follow-up program on the level of hope in a self care education program. methods: in this single-blind randomized controlled clinical trial, 75 hemodialysis patients, selected by convenient sampling, w...

In this paper we compare speech recognition accuracy for highquality speech recorded under controlled conditions with speech as it appears over long-distance telephone lines. In addition to comparing recognition accuracy, we use telephone-channel simulation to identify the sources of degradation of speech over telephone lines that have the greatest impact on speech recognition accuracy. We firs...

Firms in mobile telephone markets charge one another for delivering calls to subscribers. These so-called termination charges are controversial from a policy perspective since they are fairly high and stable. We present a model of consumer and firm behavior in mobile markets in order to identify the role of termination charges in determining the market equilibrium. We analyze three segments of ...
