Examples of human-based ground truth versus machine-based responses for Q4.

Human-based ground truth Machine-based responses
Tier 1 Not specified The applications of the Neural Beamforming Front-End described in the paper include real-time audio signal enhancement for human-computer interaction, telecommunication, web conferencing, and pro-audio applications.
Tier 2 Voice-Over-IP applications The applications of high fidelity speech regeneration with application to speech enhancement include speech enhancement for better communication and collaboration, particularly in the context of physical distancing during the COVID-19 pandemic.
Tier 3 Podcasts, video voice-overs, and audiobooks that require studio-quality audio with full bandwidth and balanced equalization (EQ) The applications of signal processing to audio and acoustics discussed in the paper are focused on speech enhancement, specifically improving the quality of real-world consumer-grade recordings to sound like studio recordings. This can be beneficial for various content creation tasks such as podcasts, video voice-overs, and audiobooks.
Tier 4 Law-enforcement related audio recordings where it’s difficult to understand the speech of one specific speaker amongst all the others The applications mentioned in the text are related to law enforcement and investigations involving audio recordings.
