Vlingo was a speech recognition software company co-founded by speech-to-text pioneers Mike Phillips (later co-founder and CEO of Sense Labs, Inc) and John Nguyen in 2006. It was best known for its intelligent personal assistant and knowledge navigator, also named Vlingo, which functioned as a personal assistant application for Symbian, Android, iPhone, BlackBerry, and other smartphones. Vlingo was acquired by speech recognition giant Nuance Communications in 2012.
The application uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to various applications. Vlingo Find and other iterations were known as first-to-market innovators in speech-to-text recognition. With adaptive hierarchical language models, Vlingo improves its speech-to-text recognition as it learns a user’s speech and search habits. It was the first technology of its kind to use adaptive hierarchical language models to learn from the corrections a user would make. Vlingo servers analyze speech queries and send any recommendations or possible corrections back to the user. This technology allows users to text, search, and navigate smartphones without typing.
Vlingo had its own application with over 5 million users in addition to partnerships with a number of companies, including Yahoo, Samsung, RIM, and Nokia. Vlingo ships by default on Samsung Galaxy S2 devices, and Vlingo worked with Samsung to create S Voice personal assistant (available on the Samsung Galaxy S3 and newer Samsung Galaxy devices.) Vlingo also powered early versions of Siri (before Siri was acquired by Apple).
