“…We created a category specifically for transformations to a real word in English (word) and a category for transformations to a nonword (nonword). Note that we did not assess the phonotactic legality or probability of the nonwords (Vitevitch & Aljasser, 2021).…”

Introduction:Five studies examined the speech to song illusion, the verbal transformation effect, and the sound to music illusion in order to determine if they were distinct phenomena and to assess if they could be accounted for by a single perceptual/cognitive mechanism. Methods:In Study 1, word lists varying in length from 1 word (as often used to study the verbal transformation effect) to 4 words (as often used to study the speech to song illusion) were presented to participants for 4 minutes to investigate the percepts that were elicited. In Study 2 participants were asked to indicate YES/NO if they experienced the speech to song illusion when listening to word-lists modified by a vocoder. In Studies 3-5 participants were asked to click a button as soon as the shift in percept occurred from speech (or sound) to a music-like percept to assess the time-course of the speech to song (or sound to music) illusion.Results: Study 1 shows that the verbal transformation effect and the speech to song illusion elicit similar percepts. In Study 2 participants indicated that the speech-like stimuli elicited the speech to song illusion more than the noise-like stimuli. In Studies 3-5 similar time-courses were observed for the speech to song illusion and the sound to music illusion.Discussion: Previous, single-mechanism accounts of the speech to song illusion are discussed, but none of them adequately account for all of the results presented here. A new model is proposed that appeals to both a perceptual/"lower-level" mechanism and a cognitive/"higherlevel" mechanism.

“…In addition to cohort and rhyme effects, phonotactic probability has been shown to influence speech perception and production sublexically at the phoneme level (for a review, see Vitevitch & Aljasser, 2021;Vitevitch & Luce, 2016). The term phonotactic probability refers to the positional frequency with which legal phonological segments and sequences of segments in a given position in a word occur according to a language .…”

Listeners are able to use previously acquired knowledge to predict the content of upcoming speech when the latter signal is distorted or degraded. The present study investigated this perceptual “pop-out” phenomenon. Previous research has shown that misperceptions (i.e., prediction errors) of single words can occur when there is near-identical overlap in phonological onset (cohort) and offset (rhyme) between prior knowledge and distorted speech with relative preservation of the temporal envelope. Here we investigated whether misperceptions during pop-out can also occur at the sentence level with spectrotemporally degraded speech that drastically reduces phoneme recognition and removes prosodic features of the acoustic-phonetic signal such as intonation and lexical tone. In a series of experiments using a probe-prime-probe design with congruent, incongruent, and neutral conditions, we presented participants with three different types of spectrotemporally degraded probe sentences: real English, nonsense (containing phonological neighbour words but semantically empty), and pseudo sentences (containing nonwords). In the nonsense and pseudo-sentence experiments, words and nonwords were phonotactically matched to the reference words using homophonic transformation. For real sentences, we observed accuracy rates of 95% in the congruent condition. Crucially, “accuracy” rates for congruent nonsense and pseudo-sentences were also high (70% and 74%, respectively), indicating participants were able to assemble lexical information from the context of the prime sentence producing ‘misperceptions’ of the probe sentence. These findings show that prior knowledge of sublexical information is largely responsible for listeners being able to predict the content of spectrotemporally degraded speech.
