Christina Tånnander

Christina Tånnander is an Industry doctoral student and Researcher at KTH Royal Institute of Technology's Division of Speech, Music and Hearing, collaborating with the Swedish Agency for Accessible Media (MTM). Her work focuses on advancing text-to-speech (TTS) synthesis for accessible media, producing spoken versions of textbooks and newspapers for individuals with reading difficulties such as dyslexia or low vision.

Her research centers on TTS for long, information-rich texts, examining the relationship between written and spoken language. Key interests include neural TTS input representations (e.g., phonemic levels, pausing), text normalization, pronunciation generation, and evaluation methodologies for synthesized speech quality. She investigates how contextual framing and prosodic features impact listener perception in educational and journalistic content.

Analysis of her publications (2013–2024) reveals consistent expertise in TTS evaluation using audience response systems, with recent emphasis (2023–2024) on neural prosody modeling, continuous phonological features, and English-accented Swedish synthesis. Her work bridges industrial application at MTM—where over 100 newspapers and 800 textbooks are annually processed—and academic innovation in speech technology.
