Blind Trial
Regression Modelling
Calibrating audio inputs to eliminate extraneous variables and ensure consistent acoustic baselines for sociolinguistic data.
Identifying and isolating specific acoustic markers and phonetic variance for targeted spectrogram analysis.
Conducting double-blind perceptual evaluation experiments to track listener judgment latency in milliseconds.
Applying statistical models to correlate acoustic features with perceptual responses, isolating dialect markers.
Hardware and Spectrogram Analysis
Our laboratory employs custom-built response timer hardware, precisely calibrated for sub-millisecond accuracy in perceptual judgment tracking. Each acoustic sample undergoes detailed spectrogram analysis, revealing frequency lines and amplitude variations critical for sociolinguistic data interpretation.
This meticulous approach ensures that our findings on accent bias are grounded in verifiable, high-resolution phonetic data, minimizing experimental noise and maximizing statistical power.
