To determine how familiarity with a talker's voice affects perception of spoken words, we trained two groups subjects to recognize set voices over 9-day period One group then identified novel words produced by the same talkers at four signal-to-noise ratios Control different The results showed that ability identify improved intelligibility talker suggest speech may involve talker-contingent processes whereby perceptual learning aspects vocal source facilitates subsequent phonetic analysis...
Spoken language is characterized by an enormous amount of variability in how linguistic segments are realized. In order to investigate speech perceptual processes accommodate multiple sources variation, adult native speakers American English were trained with words or sentences produced six Spanish-accented talkers. At test, listeners transcribed utterances familiar unfamiliar With only brief exposure, perceptually adapted accent-general regularities spoken language, generalizing novel...
This study examined how perceptual sensitivity contributes to gender differences in vocal accommodation. Male and female shadowers repeated isolated words presented over headphones by male speakers, listeners evaluated whether accommodation occurred. Female accommodated more than males, males although some speakers elicited greater others. Gender emerged even when immediate social motives were minimized, suggesting that may be due, part, characteristics.
The present study investigated the role of emotional tone voice in perception spoken words. Listeners were presented with words that had either a happy, sad, or neutral meaning. Each word was (happy, neutral) congruent, incongruent, respect to affective meaning, and naming latencies collected. Across experiments, blocked mixed results suggest facilitated linguistic processing an emotion-congruent fashion. These findings information about is used content influencing recognition manner.
Abstract This investigation examined whether speakers produce reliable prosodic correlates to meaning across semantic domains and listeners use these cues derive word from novel words. Speakers were asked phrases in infant‐directed speech which words used convey one of two meanings a set antonym pairs (e.g., big/small). Acoustic analyses revealed that some acoustic features correlated with overall valence the meaning. However, each also displayed unique signature, semantically related...
The present experiments investigated how several different sources of stimulus variability within speech signals affect spoken-word recognition. effects varying talker characteristics, speaking rate, and overall amplitude on identification performance were assessed by comparing recognition scores for contexts with without along a specified dimension. Identification word lists produced single talkers significantly better than the identical items in multiple-talker contexts. Similarly, words...
A series of experiments was conducted to determine if linguistic representations accessed during reading include auditory imagery for characteristics a talker's voice. In 3 experiments, participants were familiarized with two talkers brief prerecorded conversation. One talker spoke at fast speaking rate, and one slow rate. Each identified by name. At test, asked either read aloud (Experiment 1) or silently (Experiments 1, 2, 3) passage that they told written the talker. Reading times, both...
Foreign-accented speech contains multiple sources of variation that listeners learn to accommodate. Extending previous findings showing exposure high-variation training facilitates perceptual learning accented speech, the current study examines what extent
Abstract Although language has long been regarded as a primarily arbitrary system, sound symbolism , or non‐arbitrary correspondences between the of word and its meaning, also exists in natural language. Previous research suggests that listeners are sensitive to symbolism. However, little is known about specificity these mappings. This study investigated whether symbolic properties correspond specific meanings, generalize across semantic dimensions. In three experiments, native...
The present study investigated the degree to which perceptual adaptation foreign-accented speech is specific regularities in pronunciation associated with a particular accent. Across experiments, conditions under generalization of learning did or not occur were evaluated. In Experiment 1, listeners trained on word-length utterances Korean-accented English and tested words produced by same different set speakers. Listeners performed better than untrained controls when novel from 2, Spanish-,...
Research on vocal alignment, the tendency for language users to match another individual's speech productions, suggests that multiple factors contribute this behavior. Social and motivational goals, aspects of cognitive architecture, linguistic flexibility may all affect extent which alignment occurs, suggesting complex underlying mechanisms. The present study capitalized social characteristics Spanish-accented English examine relationship among these contributors alignment. American...
Speech sounds can communicate perceptual information through iconicity, or shared resemblance between sound and meaning. Prosody, which encompasses vocal characteristics such as pitch intensity, similarly be recruited to meaning by evoking physical features of a referent. This study used English-like pseudowords investigate whether iconicity word form object properties would affect pronunciation, with the prediction that congruent mappings label referent elicit iconic prosodic modulation....
This study examined how passage content influences attitudes toward American English Accents. Participants listened to passages differing in topic spoken an Southern or Standard accent. Although Southern-accented speakers were rated higher sociality, but lower status, than standard-accented speakers, sociality ratings varied as a function of only for speakers. Linguistic appeared most likely influence listeners’ when preexisting assumptions based on regional accent absent.
Cross-modal correspondences refer to associations between apparently unrelated stimulus features in different senses. For example, high and low auditory pitches are associated with visual elevations, respectively. Here we examined how this crossmodal correspondence elevation pitch relates elevation. We used audiovisual combinations of high- or low-frequency bursts white noise a comprising circle. Auditory stimuli could each occur at elevations. These multisensory be congruent incongruent for...
