Resource information

The dataset contains speech recordings from 18 bilingual speakers of Finnish and Russian, as well as articulation movements, which were recorded using EMA equipment in the Logolab facility at the University of Eastern Finland.
The data includes recordings of the speakers’ speech in both their first language (L1) and second language (L2), as well as speech delivered with an imitated foreign accent. The speakers’ task was to read a rainbow story, word lists (‘say [x] again’) and to describe, in their own words, the picture they had been given.
In addition to the audio data, the dataset includes articulation measurements produced using the AG5012 equipment from Carstens Medizinelektronik GmbH. In practice, these are raw text data files (in .pos format) containing X, Y and Z coordinates (as well as other data provided by the equipment). The speech data is also to be segmented automatically (forced alignment).
The data was collected between 2023 and 2025.
