This paper reports on the experience collecting a number of corpora of Nordic languages spoken by children. The aim of the data collection is providing annotated data to develop and evaluate computer assisted pronunciation assessment systems both for non-native children learning a Nordic language (L2) and for L1 children with speech sound disorder (SSD). The paper presents the challenges encountered recording and annotating data for Finnish, Swedish and Norwegian, as well as the ethical considerations related with making this data publicly available. We hope that sharing this experience will encourage others to collect similar data for other languages. Of the different data collections, we were able to make the Norwegian corpus publicly available in the hope that it will serve as a reference in pronunciation assessment research.

Proceedings of the Seventh International Conference on Language Resources and Evaluation (LREC'10)

We present the Spontal database of spontaneous Swedish dialogues. 120 dialogues of at least 30 minutes each have been captured in high-quality audio, high-resolution video and with a motion capture system. The corpus is currently being processed and annotated, and will be made available for research at the end of the project.
