Tuning the performance of automatic speaker recognition in different conditions
Automatic speaker recognition applications have often been described as a ‘black box’. This study explores the benefit of tuning procedures (condition adaptation and reference normalisation) implemented in an i-vector PLDA framework ASR system, VOCALISE. These procedures enable users to open the black box to a certain degree. Subsets of two 100-speaker databases, one of Czech and the other of Persian male speakers, are used for the baseline condi…
Between-speaker rhythmic variability is not dependent on language rhythm, as evidence from Persia reveals
Acoustic measures of speech rhythm based on the durational characteristics of consonantal and vocalic intervals (henceforth C- or V-intervals) as well as syllabic intensity reveal between-speaker variability. The evidence obtained so far is based on speakers of stressed-timed languages, which are assumed to have complex consonant clusters and a higher degree of vowel reduction. Speakers of stressed-timed languages might operate their articulatory…
A Case Study of Negative Affixes in Sadegh Hedayat’s Letters
This research studies the morphological features found in Sadegh Hedayat's letters, who, based on linguistic and psychological studies, may have had bipolar disorder. It aims to assess the impact of various types of moods on the frequency of negative affixes through qualitative analysis of the letters' text. The letters are written in Persian, and include six negative derivational affixes. As bipolar disorder includes four episodes, all letters a…
Voice onset time in Persian initial and intervocalic stop production
The purpose of this study is to examine voice onset time as a phonetic correlate of voicing distinction in standard Persian. Issues pertinent to VOT are also addressed: namely, the effect of place of articulation, vowel context and sex of speakers. The VOTs were measured from recordings of five male and five female speakers reading 65 words that contained a full set of Persian oral stops in word initial and intervocalic positions. This acoustic e…
