In this paper it is shown that a Blind Signal Separation (BSS) method in the frequency domain (FDBSS) improves significantly the speaker Signal to Interference Ratio (SIR) and the phoneme recognition score of a continuous speech, speaker-independent acoustic decoder in a multi-simultaneous-speaker office environment. Specifically, the efficiency of the presented FDBSS method is studied on a TIT...

OBJECTIVES (1) To report the speech perception and intelligibility results of Mandarin-speaking patients with large vestibular aqueduct syndrome (LVAS) after cochlear implantation (CI); (2) to compare their performance with a group of CI users without LVAS; (3) to understand the effects of age at implantation and duration of implant use on the CI outcomes. The obtained data may be used to guide...

account of the several works that came from Digby's pen and, if one might judge from his Private Memoirs, his over-active brain. But even in this involved field of authorship one fails to find a solution to the strange uncertainties and contradictions that made Digby, Digby. Even the "powder of sympathy" in all its implications affords no explanation. Nevertheless, Sir Kenelm could not well be ...

In general, speech synthesis using the source-filter model of speech production requires the classification of speech into two classes (voiced and unvoiced) which is prone to errors. For voiced speech, the input of the synthesis filter is an approximately periodic excitation, whereas it is a noise signal for unvoiced. This paper proposes an excitation model which can be used to synthesise both ...

The traffic performance of third generation mobile systems is greatly influenced by the multiple access protocols used in the radio access subsystem. The paper introduces an access protocol, SIR (Service Integration Radio Access), which has the potential for accommodating the requirements of speech and bursty data traffic in an efficient way. SIR is evolved from a protocol (PRMA++) studied in t...
