Reliability of brain-computer interface language sample transcription procedures

Katya Hill, PhD, CCC-SLP, et al.

The reliability of transcribing language samples of daily brain-computer interface (BCI) communication recorded as language activity monitor (LAM) logfiles is reported. This study determined interrater and interjudge reliability for transcription of communication of veterans with amyotrophic lateral sclerosis (ALS) using a P300- based BCI as an augmentative and alternative communication (AAC) system. The procedure was found to be highly accurate based on frequency of agreement ratio calculations across transcribers/raters. Interjudge agreement was 100% for the two selected language measures. The results indicate that transcribing language samples using LAM data is highly reliable and the fidelity of the process can be maintained.
