USC 75-Speaker Speech MRI Database

This dataset offers a unique corpus of 2D sagittal-view RT-MRI videos along with synchronized audio for 75 subjects performing linguistically motivated speech tasks, alongside the corresponding first-ever public domain raw RT-MRI data. The dataset also includes 3D volumetric vocal tract MRI during sustained speech sounds and high-resolution static anatomical T2-weighted upper airway MRI for each subject. The database, and companion software tools, are freely available to the research community.

A description of the database is given in the following article:

Nayak, Shrikanth S. Narayanan, “A multispeaker dataset of raw and reconstructed speech production real-time MRI video and 3D volumetric images,” Scientific Data 8, 187 (Nature Publishing Group) 2021.

The database is publicly available on figshare. Companion software is available on github.
