What Can an Accent Identifier Learn? Probing Phonetic and Prosodic Information in a Wav2vec2-based Accent Identification Model

no code implementations10 Jun 2023 Mu Yang, Ram C. M. C. Shekar, Okim Kang, John H. L. Hansen

This study is focused on understanding and quantifying the change in phoneme and prosody information encoded in the Self-Supervised Learning (SSL) model, brought by an accent identification (AID) fine-tuning task.
