Check Your Audio Data: Nkululeko for Bias Detection
Felix Burkhardt, Bagus Tris Atmaja, Anna Derington, Florian Eyben, Björn Wolfgang Schuller · 2024
We present a new release of the software tool Nkululeko. New additions enable users to automatically perform sanity checks, data cleaning, and bias detection in the data based on machine learning predictions. Two open-source databases from the medical domain are investigated: the Androids de-pression corpus and the UASpeech dysarthria corpus. Results show that both databases have some bias, but not in a severe manner.
