Late last month, the group celebrated 1.5 million downloads of this toolkit, which is used for speech recognition research and building speech products.

Begun as a DARPA-funded project, Sphinx is committed to widely releasing its... Read More

In an article published on May 13, the Washington Post claimed that Donald Trump routinely posed as his own public relations agent in the 1980s and 1990s, using the alias "John Miller" or "John Barron" to boast of Trump's personal and professional successes.

The old saying holds that "many hands make light work," and modern crowdsourcing efforts certainly prove that to be true. One standout example is Wikipedia, which relies on a network of people around the world to create, edit and maintain its entries. Editors on the site assume different roles according to their areas of expertise: some may add large chunks of information to an entry, while others may stick to smaller tasks like copyediting.

In the past, systems designed to route work to appropriate Wikipedia editors have focused on matching editors to articles that relate to ones... Read More

Voice-activated technologies like Siri and Cortana help facilitate communication between humans and artificial intelligence. It's a simple pattern: the human speaks, the machine processes that speech and the machine answers.

Language Technologies Institute Professor Alan Black recently spoke to about how this current model of artificial intelligence interaction results in stilted communication. He believes... Read More

A readability analysis of presidential candidate speeches by researchers in Carnegie Mellon University's Language Technologies Institute (LTI) finds most candidates using words and grammar typical of students in grades six through eight, though Donald Trump tends to lag behind the others.

A historical review of their word and grammar use suggests all five candidates in the analysis — Republicans Trump, Ted Cruz and Marco Rubio (who has since suspended his campaign); and Democrats Hillary Clinton and Bernie Sanders — have been... Read More
