Morphological effects in Estonian spontaneous speech
This study investigates the role of morphological structure and paradigmatic information in the perception of Estonian inflected forms in spontaneous speech. Using a large-scale online word-typing task, we examine how segment deletion in the base or suffix, realized inflectional paradigm size, and whole-word frequency affect typing accuracy, speed, and duration. Our results indicate that reduced words are more difficult and take longer to identif…
Beyond Sociodemographics
Moving beyond traditional sociodemographic models, this study investigates the psychometric drivers of lexical change. Using Swiss German as a case study, we compare historical data from the Sprachatlas der deutschen Schweiz (1939–1958) with a recent large-scale app-based survey (N = 1013) to quantify trajectories over the past century. We identify four distinct mechanisms: exogenous convergence (Schmetterling), endo-normative leveling (Rande), e…
Learning or Boredom? Task Adaptation Effects in Sentence Processing Experiments
Task adaptation, characterized by a progressive increase in speed throughout experimental trials, has been extensively observed across various paradigms. Yet, the underlying mechanisms driving this phenomenon remain unclear. According to the learning-based explanation, participants are implicitly learning, becoming more proficient over time. Conversely, a motivation-based view suggests that participants’ drive wanes gradually, prompting quicker p…
Predictability Associated With Reduction in Phonetic Signals Without Semantics—The Case of Glossolalia
Glossolalia can be regarded as an instance of speech production in which practitioners produce syllables in seemingly random sequences. However, a closer inspection of glossalalia’s statistical properties reveals that sequences show a Zipfian pattern similar to natural languages, with some syllables being more probable than others. It is well established that statistical properties of sequences are implicitly learned, and that these statistical p…
Modelling German Word Stress
Standard linguistic and psycholinguistic approaches to stress assignment argue that the position of word stress is determined on the basis of abstract information such as syllable weight and number of syllables in the word. In the present study, we contrasted this approach with a perspective based on learning analogies according to which speakers learn to associate basic word form cues to stress position. To do so, we use a simple two-layer neura…
Paradigmatic and Syntagmatic Effects in Estonian Spontaneous Speech
Recent evidence indicates that a word’s paradigmatic neighbors affect production. However, these findings have mostly been obtained in careful laboratory settings using words in isolation, and thus ignoring potential effects that may arise from the syntagmatic context, which is typically present in spontaneous speech. The current corpus analysis investigates paradigmatic and syntagmatic effects in Estonian spontaneous speech. Following work on En…
Stratification effects without morphological strata, syllable counting effects without counts - modelling English stress assignment with Naive Discriminative Learning
Stress position in English words is well-known to correlate with both their morphological properties and their phonological organisation in terms of non-segmental, prosodic categories like syllable structure. While two generalisations capturing this correlation, directionality and stratification, are well established, the exact nature of the interaction of phonological and morphological factors in English stress assignment is a much debated issue…
Prediction and error in early infant speech learning
In the last two decades, statistical clustering models have emerged as a dominant model of how infants learn the sounds of their language. However, recent empirical and computational evidence suggests that purely statistical clustering methods may not be sufficient to explain speech sound acquisition. To model early development of speech perception, the present study used a two-layer network trained with Rescorla-Wagner learning equations, an imp…
Articulatory Variability is Reduced by Repetition and Predictability
Repeating the movements associated with activities such as drawing or sports typically leads to improvements in kinematic behavior: these movements become faster, smoother, and exhibit less variation. Likewise, practice has also been shown to lead to faster and smoother movement trajectories in speech articulation. However, little is known about its effect on articulatory variability. To address this, we investigate the extent to which repetition…
Special Issue
In recent years, more and more evidence is accumulating that there is a great deal of variation as a result of morphological complexity, both at the level of phonology and at the level of phonetics. Such findings challenge established linguistic models in which morphological information is lost in comprehension or production. The present Special Issue presents five studies that investigate the phenomenon in more detail, centered around the follow…
Paradigmatic enhancement of stem vowels in regular English inflected verb forms
Many theories of word structure in linguistics and morphological processing in cognitive psychology are grounded in a compositional perspective on the (mental) lexicon in which complex words are built up during speech production from sublexical elements such as morphemes, stems, and exponents. When combined with the hypothesis that storage in the lexicon is restricted to the irregular, the prediction follows that properties specific to regular in…
Phonetic effects of morphology and context
Recent research on the acoustic realization of affixes has revealed differences between phonologically homophonous affixes, e.g. the different kinds of final [s] and [z] in English (Plag, Homann & Kunter 2017, Zimmermann 2016a). Such results are unexpected and unaccounted for in widely accepted post-Bloomfieldian item-and-arrangement models (Hockett 1954), which separate lexical and post-lexical phonology, and in models which interpret phonetic e…
Practice makes perfect
Many studies report shorter acoustic durations, more coarticulation and reduced articulatory targets for frequent words. This study investigates a factor ignored in discussions on the relation between frequency and phonetic detail, namely, that motor skills improve with experience. Since frequency is a measure of experience, it follows that frequent words should show increased articulatory proficiency. We used EMA to test this prediction on Germa…
Strategies for addressing collinearity in multivariate linguistic data
When multiple correlated predictors are considered jointly in regression modeling, estimated coefficients may assume counterintuitive and theoretically uninterpretable values. We survey several statistical methods that implement strategies for the analysis of collinear data: regression with regularization (the elastic net), supervised component generalized linear regression, and random forests. Methods are illustrated for a data set with a wide r…
Lexical frequency co-determines the speed-curvature relation in articulation
The relation between speed and curvature provides a characterization of the spatio-temporal orchestration of kinematic movements. For hand movements, this relation has been reported to follow a power law with exponent -1/3. The same power law has been claimed to govern articulatory movements. We studied the functional form of speed as predicted by curvature using electromagnetic articulography, focusing on three sensors: the tongue tip, the tongu…
