Abstract
PPGSpeech explores a wearable silent speech interface that leverages neck-worn photoplethysmography signals for unobtrusive speech interaction.

In IEEE Internet of Things Journal, 13(4), pp. 6692-6703
PPGSpeech investigates how neck-worn PPG signals can support silent speech interaction, extending wearable sensing beyond motion and biomechanics into subtle physiological signals for human-computer interaction.
