Spanish speakers often produce English words with initial /s/-consonant clusters with an initial [e], e.g. school as [esku:l]. This has been linked to the perception of an illusory [e] preceding acoustic [sC] sequences, but there is evidence that exposure to English can weaken this illusion, raising the possibility that late Spanish-English bilinguals can learn to distinguish tokens like eschool from school, but they map both to the target word. Lexical decision and auditory discrimination experiments confirmed this hypothesis. Late Spanish-English bilinguals accepted both pronunciations readily (from either native- or Spanish-accented talkers), but they also discriminated them easily.

Spanish speakers perceive an illusory [e] preceding word-initial [s]-consonant sequences, related to a productive loanword adaptation process, e.g. escáner from English scanner. We tracked the emergence of this illusion in 4IAX auditory discrimination. Native speakers heard initial portions of Spanish-like nonce words, e.g. estipa/astipa/stipa. The perceptual illusion was expected to hinder discrimination of pairs like estipa-stipa. For these pairs, when stimuli were truncated after the stop burst following the [s], discrimination was near ceiling although the burst confirmed the conditioning environment for the illusion. Accuracy dropped when longer portions were presented (e.g. esti-sti). The illusion is thus linguistic, not auditory.
