AI Admissions Essays Align with Privileged Male Writing Patterns

Researchers analyzed AI-generated and human-written college admissions essays, finding that AI-generated essays resemble those written by male students from privileged backgrounds. AI essays tended to use longer words and exhibited less variety in writing style than human essays, particularly resembling essays from private school applicants. The study highlights concerns about the use of AI in crafting admissions essays, as AI may dilute a student’s authentic voice. Students are encouraged to use AI as a tool to enhance, not replace, their personal narrative in writing.

Improving Voice Recognition for People with Speech Disabilities

A new study shows that automatic speech recognition (ASR) systems trained on speech from people with Parkinson’s disease are 30% more accurate in transcribing similar speech patterns. Researchers collected over 151 hours of recordings from participants with varying degrees of dysarthria, a speech disorder common in Parkinson’s patients, and used the data to train ASR systems.

This shows researchers standing around a computer monitor.
