Selected highlights[edit]

17zuoye.com, 2017: 30 million K-6 English as a Second Language student customers of independent commercial homework app assigned by teachers selecting from competing products in every province of China.

EF Education First, EF Learning Labs, Shanghai, China, 2013–2014: Improved automatic speech recognition (ASR) systems providing pronunciation assessment for English language learning by diagnosing Adobe Flash-based microphone upload channel faults, immediately reversing a 30% accuracy drop prior to my arrival. Architected, validated, and implemented further pronunciation assessment accuracy improvement using Sensory Fluentsoft ASR with phoneme duration and acoustic scores normalized by establishing a leaderboard of exemplar pronunciations from student uploads, achieving a 24% increase in scores’ agreement with a panel of human judges. Prototyped auditory feedback for pronunciation exercises, designed ASR QA systems, and additional word and phrase score improvements on cross-platform mobile and desktop ASR implementations. Several other contributions to processes, internal technical documentation, and online learning functions. Used C, JavaScript, sh, C#, and ObjectiveC on Android, iOS, Linux servers, Windows ASP.NET servers and desktop, and OS X.
