MethodDataset creation and validation
ProcedureA multimodal dataset (RVTALL) was created, comprising radio frequency (UWB and mmWave radar), visual, audio, lip landmark, and laser data. This dataset was collected from 20 participants speaking vowels, words, and sentences, totaling approximately 400 minutes of annotated speech profiles. The dataset was then validated for its potential in lip reading and multimodal speech recognition research.
