Visual emotionally charged stimuli have been shown to elicit early electrophysiological responses (e.g., Ihssen, Heim, & Keil, 2007; Schupp, Junghöfer, Weike, & Hamm, 2003; Stolarova, Keil, & Moratti, 2006). We presented isolated words to listeners, and observed, using generalized additive modeling, oscillations in the upper part of the delta range, the(More)
Variability is perhaps the most notable characteristic of speech, and it is particularly noticeable in spontaneous conversational speech. The current research examines how speakers realize the American English stops /p, k, b, g/ and flaps (ɾ from /t, d/), in casual conversation and in careful speech. Target consonants appear after stressed syllables (e.g.,(More)
Natural, spontaneous speech (and even quite careful speech) often shows extreme reduction in many speech segments, even resulting in apparent deletion of consonants. Where the flap ([inverted J]) allophone of /t/ and /d/ is expected in American English, one frequently sees an approximant-like or even vocalic pattern, rather than a clear flap. Still, the /t/(More)
DIANA is an end-to-end computational model of speech processing, which takes as input the speech signal, and provides as output the orthographic transcription of the stimulus, a word/non-word judgment and the associated estimated reaction time. So far, the model has only been tested for Dutch. In this paper, we extend DIANA such that it can also process(More)
Intelligibility and degree of accentedness are interrelated aspects of non-native speech. Previous research suggests that foreign accentedness is influenced by phonetic distance measures [7]. These distance measures may also influence the intelligibility of individual words. In the present study we further investigate the relationship between the(More)
Listeners require context to understand the highly reduced words that occur in casual speech. The present study reports four auditory lexical decision experiments in which the role of semantic context in the comprehension of reduced versus unreduced speech was investigated. Experiments 1 and 2 showed semantic priming for combinations of unreduced, but not(More)
phonological patterns and detailed phonetic patterns can combine to produce unusual acoustic results, but criteria for what aspects of a pattern are phonetic and what aspects are phonological are often disputed. Early literature on Romanian makes mention of nasal devoicing in word-final clusters (e.g. in /basm/ ‘fairy-tale’). Using acoustic, aerodynamic and(More)
Listeners require context to understand the casual pronunciation variants of words that are typical of spontaneous speech [1]. The present study reports two auditory lexical decision experiments, investigating listeners’ use of semantic contextual information in the comprehension of unreduced and reduced words. We found a strong semantic priming effect for(More)
Lexical tone identification requires a number of secondary cues, when main tonal contours are unavailable. In this article, we examine Mandarin native speakers' ability to identify lexical tones by extracting tonal information from sonorant onset pitch (onset contours) on syllable-initial nasals ranging from 50 to 70 ms in duration. In experiments I and II(More)
In this study, we examined speaker-dependent (acoustic) and speaker-independent (lexical) linguistic influences on perceived foreign accentedness. Accentedness ratings assigned to Chinese-accented English words were analyzed, taking accentedness as a continuum. The speaker-dependent variables were included as acoustic distances, measured in relation to(More)
