L2 Learners’ Lexical Inferencing: Perceptual Learning Style Preferences, Strategy Use, Density of Text, and Parts of Speech as Possible Predictors
This study was intended first to categorize the L2 learners in terms of their learning style preferences and second to investigate if their learning preferences are related to lexical inferencing. Moreover, strategies used for lexical inferencing and text related issues of text density and parts of speech were studied to determine their moderating effects and the best predictors of lexical infe...
متن کاملCross-modal Association between Auditory and Visuospatial Information in Mandarin Tone Perception in Noise by Native and Non-native Perceivers
Speech perception involves multiple input modalities. Research has indicated that perceivers establish cross-modal associations between auditory and visuospatial events to aid perception. Such intermodal relations can be particularly beneficial for speech development and learning, where infants and non-native perceivers need additional resources to acquire and process new sounds. This study exa...
متن کاملStudy on Unit-Selection and Statistical Parametric Speech Synthesis Techniques
One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...
متن کاملPresenting a Framework for Supporting Life-long Learning in Iranian public libraries and Its validation
Purpose: Since nowadays public libraries are considered lifelong learning centers, these centers must have the required standards and conditions to support lifelong learning in order that they could help society members to achieve their personal and professional learning more effectively. Accordingly, it is necessary to develop and provide a mechanism to support lifelong learning in public libr...
متن کاملRelationship between perceptual learning in speech and statistical learning in younger and older adults
Within a few sentences, listeners learn to understand severely degraded speech such as noise-vocoded speech. However, individuals vary in the amount of such perceptual learning and it is unclear what underlies these differences. The present study investigates whether perceptual learning in speech relates to statistical learning, as sensitivity to probabilistic information may aid identification...
