Human and computer recognition of regional accents and ethnic groups from British English speech

A. Hanani, M.J. Russell, M.J. Carey
2013 Computer Speech and Language  
This system is applied to the problems of regional accent recognition for British English, and ethnic group recognition within a particular accent.  ...  For the fourteen regional accents of British English in the ABI-1 corpus (good quality read speech), our language ID system achieves a recognition accuracy of 86.4%, compared with 95.18% for our best ACCDIST-based  ...  In the first volume of "Accents of English", Wells defines 'accent of English' as "a pattern of pronunciation used by a speaker for whom English is the native language or, more generally, by the community  ...

The neural bases of normalising for accented speech: A repetition suppression functional magnetic resonance imaging study

Patti Adank, Peter Hagoort
2008 Journal of the Acoustical Society of America  
Still, such tokens are usually perceived as containing a "t" or "d" ͑e.g. 'needle' even with a very reduced "d" is usually not perceived as 'kneel'͒.  ...  Degree of intensity dip has the strongest effect, with a minimal dip in intensity more likely to be perceived as 'kneel' and a strong dip in intensity more likely to be perceived as 'needle. ' The results  ...  The results indicate that normalisation processes for accented speech recruit a wide neural network. The role of left IFG in normalisation processes will be discussed.  ...

Distributed system V IPC in LOCUS: a design and implementation retrospective

B D Fleisch
1986 Proceedings of the ACM SIGCOMM conference on Communications architectures & protocols - SIGCOMM '86  
In many systems, the interface to the network server used the system's standard IPC calls. This approach appears to be much simpler than building a truly distributed OS kernel.  ...  Typically a special process, called a "network server", provided host-to-host communication and encapsulated the details of the network protocols.  ...  Although one system call was added to create a special channel to the kernel, the standard set of message system calls are used for all communication.  ...
