We're passionate about AI research that enhances the everyday experience for the millions of users interacting with our technology. We focus on implementing the latest architectures and algorithms and creating cutting-edge solutions in areas like speech recognition, text-to-speech, and speaker verification.

Our Philosophy

We work at the intersection of ML Research and ML Engineering. To a great extent, it is hard to decouple these two disciplines. ML, at its heart, is an empirical discipline. The theoretical foundations of ML are sound in certain areas and evolving in other areas as we continue to push the envelope. The projects we work on involve natural language processing, computational linguistics, large language models (LLMs), networking, security, knowledge acquisition, insight generation, and related areas.

We firmly believe in the “Farm to Table” approach to ML: where possible, we curate our own data to train our own models, and productize them through our unique ML operations (MLOps) approach for better customer experience. As part of this process, we gather new insights which we publish at peer-reviewed conferences and disseminate as technical talks.

Jordan Hosier
Principal Data Scientist Manager
A data scientist with long brown hair wearing a dark checkered blazer over a white top stands in front of a dark, blurred background.

Jordan’s work leverages her background in Computational Psycholinguistics (MA, Northwestern University) to conduct research and develop models that enable Vail technology to better process and produce human language. She possesses a strong understanding of machine learning and artificial intelligence, especially as it is informed by linguistic analysis.

Join the Fun

(no, seriously, we have a blast)

A group of seven people are gathered in a room, looking at a laptop with interest. Four individuals stand behind the seated two, who are operating the laptop, while another person stands near a whiteboard covered in equations. The atmosphere is academic and collaborative.

The freedom to build amazing solutions

FreeClimb from Vail offers a fully customizable, simplified, and scalable way to build world-class voice and SMS experiences. For over 30 years, businesses of all sizes and industries – from growing startups to Fortune 500s – have relied on FreeClimb from Vail to deliver value to their customer experiences.  

As customer expectations grow – and grow more complex – businesses need the right tools to readily adapt to specific needs with tailored solutions. FreeClimb’s enterprise-grade includes a premium carrier network running 1M+ minutes a month, a flexible range of SDKs, a voice and messaging API, and actionable insights to support agents, streamline operations, and foster brand loyalty at every turn.  

Our work continues to be inspired by the principles Jim Whiteley (Vail Systems' Founder and CEO) learned in 1961:  

"Work to make people around you better; revision is about making things better; and most importantly, the proper use of technology can change the world."

Leave legacy behind. Build beyond expectations.
