Purpose: High-variability phonetic training (HVPT) has been found to be effective on adult
second language (L2) learning, but results are mixed in regards to the benefit of multiple …

This article reviews research on when acoustic‐phonetic variability facilitates, inhibits, or
does not impact perceptual development for spoken language, to illuminate mechanisms by …

Abstract Second-language (L2) learners can benefit from exposure to phonetically variable
speech during computer-based training. Moreover, this training can be effective even for L2 …

Previous studies have yielded contradictory results on the relationship between perception
and production in second language (L2) phonological processing. We re-examine the …

Although the high-variability training method can enhance learning of non-native speech
categories, this can depend on individuals' aptitude. The current study asked how general …

Talker variability has been reported to facilitate generalization and retention of speech
learning, but is also shown to place demands on cognitive resources. Our recent study …

Background High talker variability (ie, multiple voices in the input) has been found effective
in training nonnative phonetic contrasts in adults. A small number of studies suggest that …

Acquiring non-native speech contrasts can be difficult. A seminal study by Logan, Lively and
Pisoni (1991) established the effectiveness of phonetic training for improving non-native …

Compared to low‐variability training, high‐variability training leads to better learning
outcomes and supports generalization of learning. However, it is unclear whether the …

Perceptual learning refers to a long‐term change in the ability to extract perceptual
information from the environment that arises via experience or practice. In this chapter, we …
