A small vocabulary database of ultrasound image sequences of vocal tract dynamics

TL;DR

This paper introduces a new database combining ultrasound videos of vocal tract movements with acoustic speech recordings, enabling detailed analysis of speech production in healthy speakers.

Contribution

The paper provides a novel, publicly available database of synchronized articulatory and acoustic data for speech research.

Findings

Database includes 17 subjects' ultrasound and audio data.

Data covers 30 short sentences in Spanish.

Subjects reported no speech pathology.

Abstract

This paper presents a new database consisting of concurrent articulatory and acoustic speech data. The articulatory data correspond to ultrasound videos of the vocal tract dynamics, which allow the visualization of the tongue upper contour during the speech production process. Acoustic data is composed of 30 short sentences that were acquired by a directional cardioid microphone. This database includes data from 17 young subjects (8 male and 9 female) from the Santander region in Colombia, who reported not having any speech pathology.
