Voiceprint Recognition System also known as a Speaker Recognition System (SRS) is the best-known commercialized forms of voice Biometrics. Automated speaker recognition is the computing task of validating a user's claimed identity using characteristics extracted from their voices. In contrast to other biometric technologies which are mostly image based and require expensive proprietary hardware...

Network operators have long striven to utilize equipment from multiple vendors to drive down costs. Furthermore, in competitive environments, operators have separated out functions of network elements and distributed them in order to differentiate the offered services. This trend began with deregulation in the telephone industry and promises to accelerate in the Internet age.

Until the late 1970’s, introducing new services in a telephone network was a slow and difficult process, requiring the modification of switch’s software spread all over the network. Customers might not have been happy with their dependence on their operator but they had little choice in the matter. The operators may not have been happy with their dependence on their equipment suppliers, but the...

PHS/DECT networks are “micro-cellular” radio access systems. Unlike cellular or 3G (third-generation) wireless networks they don’t require comprehensive, expensive supporting network architectures. Instead they inter-work with existing systems, such as PBXs (private branch exchanges), the PSTN (public switched telephone network), cellular networks, and ISDN (integrated services digital network)...

The NYNEX Corporation invests hundreds of millions of dollars each year to enhance the telecommunications services provided to its customers. Extensive planning and construction are required to meet the ever-increasing demand for better service and provide the latest in sophisticated equipment throughout the telephone network. Engineering groups plan changes to network facilities five years ahe...

Presentation Preference: Oral or Poster Objectives: In the United Kingdom (UK), occupational therapy (OT) is a routine component of care pathways for total hip and knee replacement. Due to the multi-modal nature of ERAS, understanding the relative importance of different component steps is difficult. Therefore, this study sought the patient’s perspective on the importance of OT input within an ...

the exposure to electromagnetic field emitted by mobile telephones is increasing rapidly worldwide that causes side effects, including thermal and non thermal side effects. ear proximity to electromagnetic source may lead to greater damage and side effects, including hearing loss. this study was performed to assess the chronic effect of exposure to electromagnetic field of mobile telephones on ...

one of the most important challenges for researchers is deciding on how to collect their data. there are various views on using telephone interviews. conducting telephone interviews on women of 40 years old and older in isfahan about mammography screening behavior showed that it could be an appropriate method for data collection when there is a combination of effective communication process and...

The impairment factor methodology has been adopted by telecommunication experts (ITU-T, ETSI) for describing the relative impact of telephone transmission degradations on the overall quality of transmitted speech. Input parameters to this methodology are mainly instrumentally measurable characteristics of the transmission path, with the exception of low bit-rate codecs, whose perceptual charact...
