Louise Ratko

Louise Ratko serves as an Academic Casual within the Department of Linguistics at Macquarie University, actively conducting research in experimental phonetics with specialized focus on Australian English speech production. Her work employs advanced instrumental techniques including ultrasound tongue imaging and electroglottography to analyze articulatory mechanisms.

Research Interests: Her primary research encompasses phonetic and phonological analysis of Australian English, specifically investigating vowel length contrasts, rhotic consonant articulation, and voiceless coda consonants. Methodologically, she specializes in ultrasound-based articulatory measurement and electroglottographic assessment of glottal states during speech production.

Publication Trends: Recent publications (2023-2025) demonstrate a cohesive research trajectory examining the phonetic realization of Australian English phonological contrasts. Key contributions include gestural characterization of vowel length, ultrasound analysis of rhotics, and electroglottographic studies of coda voicelessness, collectively advancing understanding of articulatory implementation in this dialect.

Scientific Awards: No major scientific awards are documented in available sources.

Grants and Projects: As Primary Chief Investigator, she leads the active project "Visualising Voice and Speech (VisVoiS): Bridging Experimental and Clinical Research to Accelerate Impactful Discovery" (commenced September 2022). She also served as Associate Investigator on "Visualising complex speech sounds: a study of rhotic consonants" (October 2022-October 2023), utilizing tongue ultrasound for articulatory analysis.

Collaborative Networks: Her research involves extensive collaboration with prominent phoneticians including Felicity Cox, Michael Proctor, and Jennifer Penney, reflecting active participation in international speech science communities through co-authored publications and multi-institutional projects.
