Affect-Aware AAC Prosody Modulation via OECTs
Adjust the gate bias (Vg) and cadence sliders above to visualize how organic electrochemical transistors modulate speech prosody envelopes.
PEDOT:PSS / OECT AAC Prosody Occupational Therapy
Bridging the Expressive Gap in AAC
Conventional augmentative and alternative communication (AAC) devices output flat, robotic synthetic speech, stripping non-speaking individuals of emotional nuance, urgency, and personal identity.
Neuromorphic Approach
By leveraging organic electrochemical transistors (OECTs) based on biocompatible PEDOT:PSS channels, low-amplitude physiological biosignals can continuously modulate pitch contour ($f_0$) and cadence without increasing cognitive or motor fatigue for the user.
