In this paper, we evaluate performance of model adaptation by the previously proposed HMM decomposition method[1] on telephone speech recognition. The HMM decomposition method separates a composed HMM into a known phoneme HMM and an unknown noise and channel HMM by maximum likelihood (ML) estimation of the HMM parameters. A transfer function (telephone channel) HMM is estimated using adaptation...

Epidemiologists at the University of Leeds in the United Kingdom will study victims of brain tumors over the next 3 years to determine if the use of mobile phones has contributed to the victims cancers. At the same time, the researchers will study the use of mobile phones by an equal number of people without cancer. Epidemiologist Tricia McKinney, PhD, who will lead the study said, “The causes ...

Answer. Let f(n) be the minimum number of calls needed for n people. It is easily shown that f(1) = 0, f(2) = 1, f(3) = 3 and f(4) = 4. For n > 4, 2n− 4 calls are sufficient according to the following procedure: one of four “chief” gossips first calls each of the remaining n− 4 gossips, then the four learn each other’s (and hence everyone’s) information in 4 calls (as f(4) = 4), and finally one...

Abstract A sequential mixed-mode data collection, online-to-telephone, was introduced into the National Child Development Study for first time at study's age 55 sweep in 2013. The study included a small experiment, whereby randomised subset of members allocated to single mode, telephone-only interview, order test presence mode effects on participation and measurement. Relative telephone-only, o...

Automatic transcription of telephone speech involves additional challenges compared to wideband data processing, mainly due to channel limitations and to particular characteristics of conversational telephone speech. While in TV speech recognition applications, such as automatic transcription of broadcast news, the presence of telephone data is nearly insignificant (less than 1 %), in most radi...

BACKGROUND Web interviewing is becoming increasingly popular worldwide, because it has several advantages over telephone interviewing such as lower costs and shorter fieldwork periods. However, there are also concerns about data quality of web surveys. The aim of this study was to compare the International Tobacco Control (ITC) Netherlands web and telephone samples on demographic and smoking re...
