Alejandro Baraona

Electrical and computer engineer. MS student at UT Austin, BS from Northeastern. I build AI and hardware for biomedical and assistive devices.

About

I’m a graduate student in Electrical and Computer Engineering at the University of Texas at Austin and a Graduate Research Assistant in the Wang Lab. My research focuses on personalized automatic speech recognition for people with disordered speech, including stuttering, dysarthria, and apraxia, using adaptive pipelines that improve over time for each user.

My undergraduate training at Northeastern was rooted in hardware: PCB design, embedded systems, and hands-on lab work. My graduate research builds on that foundation with software and machine learning, and I’m most at home where the two meet, building biomedical devices and tools that improve people’s lives.

Research

Personalized ASR for Disordered Speech

Developing adaptive automatic speech recognition pipelines for people who stutter or have dysarthria or apraxia. The system learns from each user over time, closing the performance gap between typical and disordered speech.

Projects

VitalLink: Wearable Triage System

A BLE wristband and base station that continuously monitor heart rate, SpO2, temperature, and motion for patients in hospital waiting rooms, and generate real-time severity scores so clinicians can prioritize care. Set with a custom PCB, firmware, and a clinical dashboard.
