The right cue, at the right moment.
Software developer & research contributor / 2025 — 2026
Interpreters listen, remember and speak at once. On-screen assistance must fit into that limited attention.
Real-time subtitles, trigger-based highlighting, WebSocket audio, transcription and terminology services.

Speech, subtitles and a place to look.

Subtitles + optional highlighting
From January 2025 to May 2026, I developed subtitle and highlighting functions and supporting audio, bilingual transcription, terminology and meeting-record services. The work supported research associated with National Social Science Fund youth project 24CYY094.
Process redrawn from the manuscript. Triggers were prepared before the task and matched exactly; the study did not automatically infer them with NLP.

A cue helps some difficulties more than others.
19 postgraduate trainee interpreters worked with and without highlighting in both Chinese–English directions. The study assessed accuracy, fluency, cognitive load and user acceptance.
The manuscript reports higher accuracy and lower perceived load. Trigger-specific gains were significant for proper nouns and terms, but not for lists or numbers.
Adding information is not the same as helping. The type of difficulty and the moment of assistance matter—a question I now want to examine in creative tools.
Prepared trigger pairs, controlled speeches and a small trainee sample. My contribution was the supporting software, not leadership of the full experimental design.

Accepted with minor revisions · editorial production pendingRevised files received in August 2026. I also contributed technical analysis to provincial project GD23WZXC01-10 and participate in the national undergraduate project on subtitle support and cognitive load. These are related contexts, not separate claims of system delivery.
