Foreign Language Learners Show a Kinematic Accent in Their Co-Speech Hand Movements
Humans typically move and vocalize in a time-synchronized fashion, aligning prominence-lending hand movements to acoustically emphasized syllables. This requires complex coordination. When speaking a foreign language, learners often place prominence on the wrong syllable in a word, which contributes to a noticeable foreign accent. In this pre-registered kinematic-acoustic study, we test whether a foreign accent is present in the timing of co-spee…
From “I dance” to “she danced” with a flick of the hands: Audiovisual stress perception in Spanish
When talking, speakers naturally produce hand movements (co-speech gestures) that contribute to communication. Evidence in Dutch suggests that the timing of simple up-and-down, non-referential “beat” gestures influences spoken word recognition: the same auditory stimulus was perceived as CONtent (noun, capitalized letters indicate stressed syllables) when a beat gesture occurred on the first syllable, but as conTENT (adjective) when the gesture o…
Is rate-dependent perception affected by linguistic information about the intended syllable rate
Speech is highly variable in rate, challenging the perception of sound contrasts that are dependent on duration. Listeners deal with such variability by perceiving incoming speech relative to the rate in the surrounding context. For instance, the same ambiguous vowel is more likely to be perceived as being long when embedded in a fast sentence, but as short when embedded in a slow sentence. However, it is still debated to what extent domain-gener…
Statistical learning at a virtual cocktail party
Statistical learning – the ability to extract distributional regularities from input – is suggested to be key to language acquisition. Yet, evidence for the human capacity for statistical learning comes mainly from studies conducted in carefully controlled settings without auditory distraction. While such conditions permit careful examination of learning, they do not reflect the naturalistic language learning experience, which is replete with aud…
Audiovisual Perception of Lexical Stress: Beat Gestures and Articulatory Cues
Human communication is inherently multimodal. Auditory speech, but also visual cues can be used to understand another talker. Most studies of audiovisual speech perception have focused on the perception of speech segments (i.e., speech sounds). However, less is known about the influence of visual information on the perception of suprasegmental aspects of speech like lexical stress. In two experiments, we investigated the influence of different vi…
Your "Voornaam" is not my "Voornaam: An acoustic analysis of individual talker differences in word stress in Dutch
Different talkers speak differently, even within the same homogeneous group. These differences lead to acoustic variability in speech, causing challenges for correct perception of the intended message. Because previous descriptions of this acoustic variability have focused mostly on segments, talker variability in prosodic structures is not yet well documented. The present study therefore examined acoustic between-talker variability in word stres…
Evidence For Selective Adaptation and Recalibration in the Perception of Lexical Stress
Individuals vary in how they produce speech. This variability affects both the segments (vowels and consonants) and the suprasegmental properties of their speech (prosody). Previous literature has demonstrated that listeners can adapt to variability in how different talkers pronounce the segments of speech. This study shows that listeners can also adapt to variability in how talkers produce lexical stress. Experiment 1 demonstrates a selective ad…
Discourse Markers Activate Their, Like , Cohort Competitors
Speech in everyday conversations is riddled with discourse markers (DMs), such as well, you know, and like . However, in many lab-based studies of speech comprehension, such DMs are typically absent from the carefully articulated and highly controlled speech stimuli. As such, little is known about how these DMs influence online word recognition. The present study specifically investigated the online processing of DM like and how it influences the…
Fluency in Dialogue: Turn-Taking Behavior Shapes Perceived Fluency in Native and Nonnative Speech
Fluency is an important part of research on second language learning, but most research on language proficiency typically has not included oral fluency as part of interactions even though natural communication usually occurs in conversations. The present study considered aspects of turn-taking behavior as part of the construct of fluency and investigated whether these aspects differentially influence perceived fluency ratings of native and nonnat…
Native speakers’ perceptions of fluency and accent in L2 speech
Oral fluency and foreign accent distinguish L2 from L1 speech production. In language testing practices, both fluency and accent are usually assessed by raters. This study investigates what exactly native raters of fluency and accent take into account when judging L2. Our aim is to explore the relationship between objectively measured temporal, segmental and suprasegmental properties of speech on the one hand, and fluency and accent as rated by n…
The Perception of Fluency in Native and Nonnative Speech
Where native speakers supposedly are fluent by default, nonnative speakers often have to strive hard to achieve a nativelike fluency level. However, disfluencies (such as pauses, fillers, repairs, etc.) occur in both native and nonnative speech and it is as yet unclear how fluency raters weigh the fluency characteristics of native and nonnative speech. Two rating experiments compared the way raters assess the fluency of native and nonnative speec…
Perceptual adaptation to segmental and syllabic reductions in continuous spoken Dutch
What makes speech sound fluent? The contributions of pauses, speed and repairs
The oral fluency level of an L2 speaker is often used as a measure in assessing language proficiency. The present study reports on four experiments investigating the contributions of three fluency aspects (pauses, speed and repairs) to perceived fluency. In Experiment 1 untrained raters evaluated the oral fluency of L2 Dutch speakers. Using specific acoustic measures of pause, speed and repair phenomena, linear regression analyses revealed that p…
Whispered speech as input for cochlear implants
In this study, we investigate whispered speech (and normal speech) as input for cochlear implants. We use normal-hearing participants presented with vocoder speech. Three tasks are involved: stress perception, gender perception, sentence melody perception and segmental intelligibility
