Area of Science:

  • Experimental Linguistics
  • Acoustic Phonetics
  • Speech Science

Background:

  • Traditional laboratory-based data collection poses accessibility challenges for some participants.
  • Mobile solutions are needed to broaden participation in speech research.
  • SPRAAKLAB addresses the need for flexible, high-quality data acquisition.

Purpose of the Study:

  • To introduce SPRAAKLAB, a mobile laboratory for speech data collection.
  • To evaluate the acoustic quality of data collected within SPRAAKLAB.
  • To demonstrate the utility of SPRAAKLAB for research and public outreach.

Main Methods:

  • Acoustic analysis of speech recordings.
  • Measurements included transmission loss, signal-to-noise ratio (SNR), and harmonics-to-noise ratio (HNR).
  • Data collected both inside and outside the mobile laboratory.

Main Results:

  • Acoustic measures confirm consistent, high-quality speech data acquisition.
  • SPRAAKLAB demonstrates effectiveness even in noisy environments.
  • The mobile lab achieved favorable transmission loss, SNR, and HNR.

Conclusions:

  • SPRAAKLAB is a viable tool for collecting high-quality speech data.
  • The mobile laboratory enhances accessibility and facilitates participant recruitment.
  • SPRAAKLAB supports both research data collection and public engagement initiatives.
