Altering context speech rate can cause words to appear or disappear.

چکیده
Speech is produced over time, and this makes sensitivity to timing between speech events crucial for understanding language. Two experiments investigated whether perception of function words (e.g., or, are) is rate dependent in casual speech, which often contains phonetic segments that are spectrally quite reduced. In Experiment 1, talkers spoke sentences containing a target function word; slowing talkers' speech rate around this word caused listeners to perceive sentences as lacking the word (e.g., leisure or time was perceived as leisure time). In Experiment 2, talkers spoke matched sentences lacking a function word; speeding talkers' speech rate around the region in which the function word had been embedded in Experiment 1 caused listeners to perceive a function word that was never spoken (e.g., leisure time was perceived as leisure or time). The results suggest that listeners formed expectancies based on speech rate, and these expectancies influenced the number of words and word boundaries perceived. These findings may help explain the robustness of speech recognition when speech signals are distorted (e.g., because of a casual speaking style).

Rate-dependent speech processing can be speech-specific: Evidence from the disappearance of words under changes in context speech rate
Function words in casual speech can be made to disappear by slowing the surrounding speech rate [1]. The current study explored the domain generality of this disappearing word effect, asking whether function words can be made to disappear by manipulating temporal properties of nonspeech context. Stimuli were short word sequences (e.g., minor or child) appended to precursors that were either spe...
متن کاملReal-time expectations based on context speech rate can cause words to appear or disappear
To test predictions of a forward modeling framework for spoken language processing, we characterized effects of context speech rate on the real-time interpretation of indefinite noun phrases using the visual world paradigm. The speech rate of sentence material distal to the onset of the noun phrase was manipulated such that the segments surrounding the determiner a in singular noun phrases had ...

Recent findings show that altering the speech rate of the context several syllables away from a word (i.e., the distal context) can cause the word to disappear in perception in non-tonal Indo-European languages like English [1] and Russian [2]. This study investigated the distal rate effect in Chinese Mandarin, a tonal language belonging to the Sino-Tibetan language family. We examined whether ...

The perception of reduced syllables, including function words, produced in casual speech can be made to disappear by slowing the rate at which surrounding words are spoken (Dilley & Pitt, Psychological Science, 21(11), 1664-1670. doi: 10.1177/0956797610384743 , 2010). The current study explored the domain generality of this speech-rate effect, asking whether it is induced by temporal informatio...
متن کاملNew tests of the distal speech rate effect: examining cross-linguistic generalization
Recent findings [Dilley and Pitt, 2010. Psych. Science. 21, 1664-1670] have shown that manipulating context speech rate in English can cause entire syllables to disappear or appear perceptually. The current studies tested two rate-based explanations of this phenomenon while attempting to replicate and extend these findings to another language, Russian. In Experiment 1, native Russian speakers l...
