Through various research projects and coursework, I have had the opportunity to build a bunch of systems.
I have developed the Basilica architecture for building Conversational Agents. Using this architecture, i created the NineOneOne Interpreter Agent that facilitates communication between Spanish speaking callers and English speaking dispatch officers. Also, this architecture was used to create conversational agents that could support students in interactive environments like SecondLife (paper) and other educational games.
As my course project in the Dialog Lab, i developed a prototype of the ConQuest dialog system. In 2007, i extended the Cognitive Tutors Authoring Tools to allow multiple (remotely-located) students to work together on learning activities (paper). Also, i worked on a Natural Language Generation system that could create several variations of word-problems about fractions. This experience helped me develop authoring tools (paper) during my internship at Alelo. I have developed and maintained the CycleTalk tutoring system since 2005.
While working at the Speech Lab in IIIT Hyderabad, i developed apps like Tourist Guide and English-Hindi Dictionary for a handheld device. One of the challenges included modifying a concatenative speech synthesizer to a tiny memory & storage footprint. Also, i developed a telephone-based data collection system that was used to collect one of the largest Indian Language speech corpus. As a pet project, i developed a News aggregator that collected and unified news from five of the major Hindi news websites.
My Undergraduate thesis project was an Indian Language Email client capable of reading out incoming mail. This was recognized as the best final year project in my batch. Back in 2002, I (with Rahul & Ritvik) developed the first Indian Language chatbot, Deepti, as a pet project.
