Probing Neural Audio Codecs with Speaker Traits and Speech Characteristics
Jihwan Lee, Tiantian Feng, Minu Kim +6
Neural audio codecs are increasingly used for low-bitrate speech coding and serve as tokenizers for speech language models, yet it remains unclear how their codebook hierarchies en…

Attack-Dependent Robustness of Neural Audio Codecs for Adversarial ASR
Jordan Prescott, Thanathai Lertpetchpun, Shrikanth Narayanan
Neural audio codecs impose a discrete bottleneck through residual vector quantization (RVQ), making them a useful class of inference-time transformations for reducing adversarial p…

ARTI-6: Towards Six-dimensional Articulatory Speech Encoding
Jihwan Lee, Sean Foley, Thanathai Lertpetchpun +6
We propose ARTI-6, a compact six-dimensional articulatory speech encoding framework derived from real-time MRI data that captures crucial vocal tract regions including the velum, t…
