Lexically guided phonetic retuning of foreign-accented speech and its generalization.

Journal of Experimental Psychology: Human Perception and Performance Lexically Guided Phonetic Retuning of Foreign-Accented Speech and Its Generalization

Lexically guided retuning of visual phonetic categories.

Listeners retune the boundaries between phonetic categories to adjust to individual speakers' productions. Lexical information, for example, indicates what an unusual sound is supposed to be, and boundary retuning then enables the speaker's sound to be included in the appropriate auditory phonetic category. In this study, it was investigated whether lexical knowledge that is known to guide the ...

Positional effects in the lexical retuning of speech perception.

Listeners use lexical knowledge to adjust to speakers' idiosyncratic pronunciations. Dutch listeners learn to interpret an ambiguous sound between /s/ and /f/ as /f/ if they hear it word-finally in Dutch words normally ending in /f/, but as /s/ if they hear it in normally /s/-final words. Here, we examined two positional effects in lexically guided retuning. In Experiment 1, ambiguous sounds du...

Speech motor brain regions are differentially recruited during perception of native and foreign-accented phonemes for first and second language listeners

Brain imaging studies indicate that speech motor areas are recruited for auditory speech perception, especially when intelligibility is low due to environmental noise or when speech is accented. The purpose of the present study was to determine the relative contribution of brain regions to the processing of speech containing phonetic categories from one's own language, speech with accented samp...

Listeners retune phoneme categories across languages.

Native listeners adapt to noncanonically produced speech by retuning phoneme boundaries by means of lexical knowledge. We asked whether a second language lexicon can also guide category retuning and whether perceptual learning transfers from a second language (L2) to the native language (L1). During a Dutch lexical-decision task, German and Dutch listeners were exposed to unusual pronunciation ...
