Data Collection Software
Overview
The data collection software is custom-built for simultaneous recording and monitoring of paired speech signals from throat and acoustic microphones. The software provides real-time monitoring to ensure recording quality, automatic file naming for organized data management, and session tracking to simplify data handling.
Before data is saved, the software applies a dedicated signal processing pipeline, which includes a 5th-order Butterworth high-pass filter (50 Hz cutoff), DC offset removal, signal normalization, and precise timing synchronization between the two microphones.
Captured signals are saved directly to the laptop in a standardized WAV file format (32-bit), with the throat microphone data upsampled to 16 kHz and the acoustic microphone data sampled at 16 kHz. Files follow a consistent naming convention to facilitate straightforward dataset usage.
