What was measured

Voice preservation

After cleanup, does the voice still sound natural, or hollow, robotic, underwater, or artifacted?

decisive for this rankingtransformation

Noise cleanup is only useful if the speech still sounds natural and intelligible after processing. (3 of 3 judges)

Outdoor Balcony Birds, Vehicles, and Surrounding Noise

A real-world outdoor speech recording captured on a balcony with variable environmental noise such as birds and traffic. It is designed to test performance on more dynamic, unpredictable background sound.

Why this input is hard

· Suppression of variable outdoor environmental noise
· Speech preservation in changing acoustic conditions
· Reduction of birds and vehicle traffic sounds
· Overall enhancement of noisy field recordings

Output — unretouched

Handling different noise types◐ MixedHandles continuous environmental noise such as birds and outdoor ambience better than transient contact noise, but performance varies by noise type and degrades on chair movement sounds.Noise removal effectiveness◐ MixedRemoves several outdoor background noises, including ambient noise and bird chirping around 0:17, but does not fully suppress transient chair noise at the start of the recording.
