An Approach to Simultaneous Acquisition of Real-Time MRI Video, EEG, and Surface EMG for Articulatory, Brain, and Muscle Activity During Speech Production

Jihwan Lee, Parsa Razmara, Kevin Huang +16

Speech production is a complex process spanning neural planning, motor control, muscle activation, and articulatory kinematics. While the acoustic speech signal is the most accessi…

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…

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…
