Pioneering voice computing research

Join us as we solve the biggest problems in voice computing.

Problems we're solving

We're researching things at the edge of of voice science - from diagnosing diseases with new machine learning models to building open-source voice assistants.


Data collection / cleaning

We're creating new protocols for how to collect and clean voice data.


Feature embeddings

We're making new feature embeddings for voice, text, image, and video data.


Machine learning 

We're curating new speech datasets to classify emotions, accents, gender, and age.



We're looking at new ways we can automatically generate text and voice data.



We're innovating the process of visualizing audio, text, and image data with Elastic Search and Kibana.


Voice assistants

We've open sourced our own voice assistant, Nala, written completely in Python. 


Server architectures

We're researching new distributed computing server paradigms for voice computing.


Security, legal, and ethical frameworks

We're researching new security, legal, and ethics frameworks to maximize consumer protections.

Our Team

We're an interdisciplinary group of engineers, computer scientists, physicians, lawyers, designers, and researchers working to translate work in voice computing into products.

Hack Anxiety is the first Hack-X format that we hosted at Georgia Tech. The idea is to have a 3 hour Hack-a-thon format for innovators to come up with solutions in voice computing related around real problems - in this case, diagnosing and managing anxiety disorders.
