Typically, the point vowels [i, ɑ, u] are acoustically more peripheral in infant-directed speech
(IDS) compared to adult-directed speech (ADS). If caregivers seek to highlight lexically …

There is growing evidence that dog-directed and infant-directed speech have similar
acoustic characteristics, like high overall pitch, wide pitch range, and attention-getting …

This paper examines the effects of lexical stress and speech rate on vowel quality and
duration in Central Catalan and Iberian Spanish and compares the patterns of phonetic …

In this study we investigate vowel reduction and the role of some lexical factors in the
production of vowels extracted from a corpus of French conversations. Vowel durations and …

Speech, though communicative, is quite variable both in articulation and acoustics, and it
has often been claimed that articulation is more variable. Here we compared variability in …

The second half of the 20th century was the dawn of information technology; and we now
live in the digital age. Experimental studies of prosody develop at a fast pace, in the context …

We set this discussion in the context of a critique of strongly modular approaches to the
phonetics/phonology interface. We ask whether phonological labels are in any way relevant …

Many approaches to sound change attempt to derive common patterns of sound change
from universal pressures, such as physiological and psychoacoustic constraints on speech …

Evaluating L2 pronunciation via acoustic measures is problematic. In the literature, this is
sometimes accomplished via fluency metrics (speech rate, average length of IPUs, etc) …

Measures of second language (L2) learners' vocabulary size have been shown to correlate
with language proficiency in reading, writing and listening skills, and vocabulary tests are …
