Better speech communication and learning in the classroom

At this years Transitions18 Education research seminar in Copenhagen, Viveka Årlander Lyberg Associate Professor at Lund University, presented the latest developments around Suvi Karjulainen’s PhD “Better communication and learning in the classroom”.

This unique and applied study around the quality of speech communication for teachers and students also links to the investigation of the classroom acoustic conditions particularly around the quality of speech intelligibility. The study has reviewed the relevant aspects around logopedics, phoniatrics and vocology. The methods of assessment include self assessments of self-efficacy, well-being and health before and after intervention.

Background issues around teachers voice quality

Occupational voice isuues for teachers and the affects on childrens understanding and attitudes.


The overall aims are to increase teachers’ knowledge and strengthen practical skills in using evidence based language learning interactions:

  • using healthy voice technique
  • optimising non-verbal communication
  • improving language learning environments

The research questions covered in the intervention study.

How noise impacts students and their learning.

Next steps around the ongoing study

Researcher, Suvi will be comparing acoustic qualities around speech intelligibility and in particular looking at speech clarity (C50) values. She will focus on a potential breakpoint in the values above and below 6dB to see what affect this has and what can be learned from this to ensure future classrooms maintain good speech communication for both the teachers voice and the listener.
