About

Sonja Schaeffler is a phonetician whose research explores the intricate relationship between speech acoustics, speaker identity, and social context. Her key research areas include the acoustics of speech registers, particularly the subtle acoustic features that differentiate intimate from neutral speech across diverse speaker-addressee constellations. In her highly cited 2008 paper, "Mothers, adults, children, pets — towards the acoustics of intimacy," Schaeffler investigates how mothers, women without children, and other speakers modulate their voices when addressing infants, adults, or even pets, revealing the acoustic signatures of emotional closeness and caregiving. This work has garnered 23 citations and remains foundational for understanding how social bonds shape vocal production. Beyond this, Schaeffler’s broader contributions examine how phonetic variation reflects speaker identity, including gender and regional background, and how listeners use these cues in perception. Her research has implications for fields ranging from developmental psychology to human-computer interaction. With a career marked by careful experimental design and interdisciplinary reach, Schaeffler continues to illuminate the acoustic fabric of human connection, making her work essential reading for students and researchers in phonetics, sociolinguistics, and communication science.
