This paper continues the examination of deletion, reduction, and reorganization phenomena in spontaneous German speech1and adduces data from English laboratory speech to establish cross-linguistic similarities between vowel deletion in German and vowel devoicing in English. We describe how two sets of data were gathered: one of Standard Southern British English (S.S.B.E.) that establishes the g...

Research into auditory analysis in forensic speaker identification has attracted little attention, yet it is regarded as an essential component of forensic speaker identification. One possible reason for this lack of interest may be associated with the difficulty of knowing how to present the results of auditory analysis in a logical and quantifiable way. The use of likelihood ratios enables th...

This study aims to examine acoustic characteristics of English vowels produced by 1 Australian English talker and 3 Japanese learners of English in spontaneous speech. Primary stressed vowels in multi-syllabic words were extracted from five 15minute interview sessions. While there was a considerable overlap between different vowel categories both in native and nonnative vowel spaces, centroids ...

In addition to summarising previous research, we present new data and highlight its relevance for phonological theory. The paper focuses primarily on processes backness harmony, rounding vowel reduction. Particular attention is paid complex, sometimes opaque, int...

This article analyzes the process of vowel reduction in function words by Brazilian speakers of English as a Foreign Language. It compares information obtained by perceptual verification with those obtained by acoustic verification. The sample is composed by sixteen female speakers of English as a FL and one native speaker of English. Data collection was accomplished through an instrument compo...

in this article, the low back vowel /a/ in word-final positions in eghlidian dialect, one of persian dialects, is studied. this vowel is represented phonetically as [a], [o] and [@] in different phonetic environments. therefore many words were collected via interviewing ten native speakers so that these different alternant forms can be accounted for appropriately. since one of the authors of th...

this paper reports the results of an experimental study on non-native production of english vowels. two groups of persian efl learners varying in language proficiency were tested on their ability to produce the nine plain vowels of american english. vowel production accuracy was assessed by means of acoustic measurements. ladefoged and maddison’s (1996) f1 f2 measurements for american english v...

In Tokyo Japanese, vowel devoicing is a common process leading to the reduction of high, unstressed vowels, mostly when they occur between unvoiced consonants. Native Japanese speakers learning German show a strong tendency to produce these devoiced vowels in the foreign language, too, despite the lack of this regular process in that language, here in German. This study examines the extent to w...
