Query: Cross-lingual Self-Supervised Speech Representations for Improved
  Dysarthric Speech Recognition   State-of-the-art automatic speech recognition (ASR) systems perform well on
healthy speech. However, the performance on impaired speech still remains an
issue. The current study explores the usefulness of using Wav2Vec
self-supervised speech representations as features for training an ASR system
for dysarthric speech. Dysarthric speech recognition is particularly difficult
as several aspects of speech such as articulation, prosody and phonation can be
impaired. Specifically, we train an acoustic model with features extracted from
Wav2Vec, Hubert, and the cross-lingual XLSR model. Results suggest that speech
representations pretrained on large unlabelled data can improve word error rate
(WER) performance. In particular, features from the multilingual model led to
lower WERs than filterbanks (Fbank) or models trained on a single language.
Improvements were observed in English speakers with cerebral palsy caused
dysarthria (UASpeech corpus), Spanish speakers with Parkinsonian dysarthria
(PC-GITA corpus) and Italian speakers with paralysis-based dysarthria (EasyCall
corpus). Compared to using Fbank features, XLSR-based features reduced WERs by
6.8%, 22.0%, and 7.0% for the UASpeech, PC-GITA, and EasyCall corpus,
respectively.
