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)

Indoor AC + Fan Background Noise

A real-world indoor speech recording with continuous background noise from both an air conditioner and a fan. It is designed to test whether tools can suppress overlapping mechanical noise while preserving speech naturalness.

Why this input is hard

· Removal of multiple overlapping indoor mechanical noises
· Speech enhancement and isolation
· Voice quality preservation under steady noise
· Minimal-artifact background noise suppression

Adobe Podcast Enhance◐ MixedSpeech stayed clear, but the tool noticeably changed the speaker's tone; the cleaned audio sounded processed and less natural than the original.Audo Studio✓ WorkedThe cleaned speech remains natural and clear, without introducing robotic artifacts or an artificial-sounding voice.Auphonic⚠ StruggledThe cleaned speech stayed clear and understandable, but the voice sounded more processed, slightly robotic, and louder than the original, reducing naturalness.Cleanvoice⚠ StruggledKeeps speech clear and understandable, but noticeably changes the speaker’s tone and character, so the cleaned voice sounds different from the original recording.ElevenLabs Voice Isolator✓ WorkedThe cleaned audio kept the speaker's original natural tone, clarity, and speaking style, with no significant robotic effects, pitch changes, or speech distortion.
