Net-set is a colorful, fast-paced, competitive card game you play in the browser. It’s inspired by the real-life card game Set®.
Kimi (“Keep It MInimal”) is a lisp-like toy programming language I created to learn more about programming languages and interpreters. Its interpreter was built in Python 3 using Test-Driven Development. Kimi is a small, elegant language with a minimal set of features (see the Readme for more details).
lex4all is a Windows desktop app written in C#. Implementing an algorithm for automatic pronunciation discovery, it uses Microsoft’s speech recognition engine for a high-resource language (e.g. English) to generate pronunciations for words in a low-resource language (e.g. Yoruba) from a handful of audio samples. Thanks to a simple GUI, the app allows even non-expert users to develop pronunciation lexicons to enable the creation of speech interfaces even in languages for which no large-vocabulary recognition engines are available. For more information, see the project website and the related publications available there.
This prototype Computer-Assisted Pronunciation Training (CAPT) tool provides a variety of options for diagnosis of and feedback on a type of pronunciation error that is commonly problematic for French learners of German. A web app built with Groovy and the Grails framework, its backend builds upon two Java applications: JSnoori (speech processing and analysis) and Weka (machine learning).
Deeva is a platform for experimental research on the personality traits associated with 3D virtual human avatars. It collects crowdsourced judgments about avatars and uses these to drive a genetic algorithm to progressively “evolve” avatars representative of various personality traits.
The prototype for the platform was created as a group project in the C.S. course “Software Engineering” at Saarland University. In addition to helping design and code the web application in Python/Django, my individual contributions included implementing the genetic algorithm, writing and revising project requirements, and using RedMine to manage the project and lead our 3-person team in meeting goals.
BrainLord is an implementation of a guessing game where the player attempts to break a secret color code. Additional features include adjustable difficulty level and a leaderboard of high scores. It is a cross-platform desktop app written in Python 3 using the TkInter package.
Built using D3, this responsive, interactive chart displays the relative frequency of letters in various languages, sorted in descending order.
