An Audio-Ultrasound Synchronized Database of Tongue Movement for Mandarin speech

Ultrasound imaging has been widely adopted in speech research to visualize dynamic tongue movements during speech production. These images are universally used as visual feedback in interventions for articulation disorders or visual cues in speech recognition. Nevertheless, the availability of high-quality audio-ultrasound datasets remains scarce. The present study, therefore, aims to construct a multimodal database designed for Mandarin speech. The dataset integrates synchronized ultrasound...
