Skills

Speech Processing

The primary application area for my capabilities in {machine learning, software development, signal processing}. I have led data collections, used an array of toolkits such as {Sphinx4, SONIC, SRILM, MITLM, HTK, Kaldi} for creation and tuning of speech models to drive speech recognition, built-from-scratch and used 3rd party libraries for speaker diarization, led analyses/experiments/applications driven by speech processing across multiple computing environments (e.g., HPC cluster, big data cluster, single server) and use cases (e.g., batch processing or online decoding).

Machine Learning

Used in support of speech recognition research, experiments, and work applications.

Software Development

Long running professional and academic experience with multiple languages; current and extensive use with JAVA and MATLAB. I have until recently worked extensively in Python and C/C++.

Signal Processing

Used extensively for speech processing experiments to support work at The MITRE Corporation, and in my role at Garmin to handle sonar return data.
