# SPRAAKLAB - mobile laboratory for speech recorded acoustically and kinematically

## TL;DR

SPRAAKLAB is a mobile lab that collects high-quality speech data outside traditional university settings, making it easier for participants to take part in linguistic research.

## Contribution

The novelty lies in demonstrating a mobile setup that maintains high-quality speech data collection in non-laboratory environments.

## Key findings

- SPRAAKLAB recordings show consistent quality in terms of transmission loss, signal-to-noise ratio, and harmonics-to-noise ratio.
- The mobile lab is effective for collecting speech data even in noisy environments.
- SPRAAKLAB supports easier data collection and enhances public outreach in experimental linguistics.

## Abstract

Data collection in experimental linguistics is frequently conducted in laboratory rooms within a research institute, which can be difficult to reach for some participants, for example, those with mobility issues or living further away and in remote areas. This article presents SPRAAKLAB, a mobile laboratory that facilitates the collection of high-quality acoustic and articulatory data outside of university walls, thus bringing the laboratory environment closer to the participants. We present an acoustic analysis of recordings collected inside and outside of the SPRAAKLAB, including transmission loss, signal-to-noise ratio, and harmonics-to-noise ratio. All three measures reveal that the SPRAAKLAB is suitable for collecting consistent, high-quality speech data even in loud environments. Finally, we discuss how the SPRAAKLAB allows us to collect data more easily and facilitates public outreach activities.
