Abstract-This paper discusses the theoretical basis for representation of a speech signal by its short-time Fourier transform. The results of the theoretical studies were used t o design a speech analysis-synthesis system which was simulated on a general-purpose laboratory digital computer system. The simulation uses the fast Fourier transform in the analysis stage and specially designed finite duration impulse response filters in the synthesis stage. The results of both the theoretical and computational studies lead to an understanding of the effect of several design parameters and elucidate the design tradeoffs necessary to achieve moderate information rate reductions.

Direct Recordings from the Auditory Cortex in a Cochlear Implant User

“…A 3-month hearing aid trial provided no benefit. Word recognition testing conducted at the time resulted in scores of 0 % on all of the following tests: spondee recognition, Northwestern University #6 words (Tillman and Carhart 1966), and Central Institute of the Deaf sentences (Hirsh et al 1952).…”

A Model for Predicting Intelligibility of Binaurally Perceived Speech

“…The speech material was the "Auditec of Saint Louis" recording made by a male talker reading words from four CID W-22 lists (Hirsh et al, 1952). Each list consists of 50 phonemically balanced, monosyllabic English words.…”

“…For example, SII (ANSI, 1997) has different importance functions for nonsensical syllables and monosyllabic words (NU-6, Northwestern University Auditory Test No. 6, Tillman & Carhart, 1966;CID W-22, Central Institute for the Deaf, Hirsh et al, 1952;DRT, Diagnostic Rhyme Test, Fair2banks, 1958;and MRT, Modified Rhyme Test, House, Williams, Hecker, & Kryter, 1963) and short passages (CST, Connected Speech Test, Cox, Alexander, & Gilmore, 1987, and SPIN, Speech Perception in Noise, Kalikow, Stevens, & Elliott, 1977). There is an option to adjust SII, depending on the vocal effort of the talker.…”

The speech audiometry test with the verbal tasks and motor responses

“…Однако наиболее широкое распространение получили словесные таблицы, представляющие собой группы из от-дельных 20-50 одно-или многосложных слов. В связи с тем, что большая часть речевого общения в повседневной жизни предполагает использование смысловых предло-жений со сложными грамматическими структурами, был разработан фразовый тест [3]. В наши дни фразовые тесты находят свое применение главным образом при услож-ненной речевой аудиометрии (для уточнения топики по-…”
