From Environmental Monitoring to Mitigation Action: Considerations, Challenges, and Opportunities for HCI

Noise pollution is among the most consistently cited and highest impact quality-of-life issues in major urban areas across the US, with more than 70 million people estimated to be exposed to noise levels considered harmful. While HCI and CSCW has a relatively rich history of engagement with monitoring such environment…

Eliciting Confidence for Improving Crowdsourced Audio Annotations

In this work we explore confidence elicitation methods for crowdsourcing “soft” labels, e.g., probability estimates, to reduce the annotation costs for domains with ambiguous data. Machine learning research has shown that such “soft” labels are more informative and can reduce the data requirements when training superv…

Crowdsourcing Multi-label Audio Annotation Tasks with Citizen Scientists

Annotating rich audio data is an essential aspect of training and evaluating machine listening systems. We approach this task in the context of temporally-complex urban soundscapes, which require multiple labels to identify overlapping sound sources. Typically this work is crowdsourced, and previous studies have shown…

Seeing Sound: Investigating the Effects of Visualizations and Complexity on Crowdsourced Audio Annotations

Audio annotation is key to developing machine-listening systems; yet, effective ways to accurately and rapidly obtain crowdsourced audio annotations is understudied. In this work, we seek to quantify the reliability/redundancy trade-off in crowdsourced soundscape annotation, investigate how visualizations affect accur…
