Arti-JEPA: Adapting Video World Model to Real-Time MRI of the Vocal Tract for Speech-Production Analysis

Hong Nguyen, Sean Foley, Christina Hagedorn +4

Real-time MRI (rtMRI) captures the dynamics of the entire vocal tract during speech, but labeled data are scarce and the modality - single-slice, grayscale, low-resolution - differ…

Learning-free L2-Accented Speech Generation using Phonological Rules

Thanathai Lertpetchpun, Yoonjeong Lee, Jihwan Lee +3

Accent plays a crucial role in speaker identity and inclusivity in speech technologies. Existing accented text-to-speech (TTS) systems either require large-scale accented datasets…

Accent Vector: Controllable Accent Manipulation for Multilingual TTS Without Accented Data

Thanathai Lertpetchpun, Thanapat Trachu, Jihwan Lee +3

Accent is an integral part of society, reflecting multiculturalism and shaping how individuals express identity. The majority of English speakers are non-native (L2) speakers, yet…

Quantifying Speaker Embedding Phonological Rule Interactions in Accented Speech Synthesis

Thanathai Lertpetchpun, Yoonjeong Lee, Thanapat Trachu +4

Many spoken languages, including English, exhibit wide variation in dialects and accents, making accent control an important capability for flexible text-to-speech (TTS) models. Cu…
