-
Visipitch (extraction and analysis of pitch)
-
Real-Time Pitch (visualization of pitch in real time for biofeedback for patients with speech and voice disorders)
-
Motor Speech Profile (measures diadochokinetic rates, durations and coarticulation features for assessment of motor speech disorders)
-
Real-Time Spectrogram (provides biofeedback for treatment of articulation disorders)
-
Sona-Match (used for biofeedback for treatment of articulation disorders)
-
Voice Games (games for therapy of voice disorders)

ELECTROGLOTTOGRAPH (EGG)
The Voice Vista Electroglottograph provides noninvasive measurement of the degree of contact between the vibrating vocal folds during voice production.
Students learn how to use the EGG for voice assessment in class!
AAC DEVICES TO PROVIDE TELETHERAPY TO CHILDREN IN ETHIOPIA
UN project on teletherapy for Ethiopian orphans :
The project aims to bring speech pathology care for children in Ethiopia by teletherapy.
We are at present focusing on providing assessment and therapy for children with communication disorders at the Sele Enat Mahiber orphanage in Addis Ababa
