This research investigates sound length in speech, comparing its physical and mental representation across languages. While English treats length as phonetic variation, languages like Japanese use it meaningfully. The study focuses on Persian to improve speech recognition and therapy, helping determine how sound duration is perceived, produced, and processed cognitively.

This research examines sound symbolism—the idea that certain sounds inherently convey meaning. Through cross-linguistic analysis of animal names, it investigates how phonetic features relate to perceived traits like size or danger. Findings could improve language learning, branding, and understanding of how human language evolved beyond arbitrary sound-meaning relationships.

This research explores how accents form in multilingual Malaysia, showing that subtle combinations of consonant and vowel features distinguish speakers. Even a single word carries identifiable acoustic cues. The findings highlight how listeners rapidly perceive identity through speech and emphasize the human complexity underlying language in an era of speech technology.

This research compares English and German preposition use, focusing on when prepositions can be dropped in short answers. Through speaker judgments of dialogue naturalness, it shows that flexibility is context-dependent rather than a simple English–German contrast, revealing subtle grammatical and structural influences.

This research investigates why children struggle to learn pronouns and why these difficulties vary across languages. Through cross-linguistic experiments and eye-tracking, it shows that pronouns pose an intrinsic processing challenge. Some languages compensate for this difficulty, offering new insights into language development and human learning.
