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…

Interpretable Modeling of Articulatory Temporal Dynamics from real-time MRI for Phoneme Recognition

Jay Park, Hong Nguyen, Sean Foley +4

Real-time Magnetic Resonance Imaging (rtMRI) visualizes vocal tract action, offering a comprehensive window into speech articulation. However, its signals are high dimensional and…

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…

A long-form single-speaker real-time MRI speech dataset and benchmark

Sean Foley, Jihwan Lee, Kevin Huang +4

We release the USC Long Single-Speaker (LSS) dataset containing real-time MRI video of the vocal tract dynamics and simultaneous audio obtained during speech production. This uniqu…

On the Relationship between Accent Strength and Articulatory Features

Kevin Huang, Sean Foley, Jihwan Lee +3

This paper explores the relationship between accent strength and articulatory features inferred from acoustic speech. To quantify accent strength, we compare phonetic transcription…

Towards disentangling the contributions of articulation and acoustics in multimodal phoneme recognition

Sean Foley, Hong Nguyen, Jihwan Lee +4

Although many previous studies have carried out multimodal learning with real-time MRI data that captures the audio-visual kinematics of the vocal tract during speech, these studie…
