  • 1 for a person

    Users get clearer speech in their videos, a convenience.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Not isolated. Which? tested the tools directly, so the sound that it judged was the tools' own output. It compared the three phones with one another and did not compare the tools with manual audio editing. The article presents the tools among the phones' AI features and does not describe the models behind them.

    Which? (Adam Speight). Apple vs Google vs Samsung: which phone has the best AI? 1 August 2025. Which? tested the phones' AI features side by side in its labs. Section on photo, video and image tools, Audio Mix and Audio Eraser test.

    This was a close-run thing in our testing, with all three phones producing good and comparable results. They all successfully reduced constant background noise and harsh, sporadic sounds.
    Modern phone AI is improving how we manage and edit our photos and videos. These tools can help you find a specific memory in a library of thousands, automatically clean up your pictures by removing unwanted people or objects, and even improve the audio in your videos.

AI system

Workflow

Which? Tested the audio tools of three phones side by side in its labs. The tools reduced background noise in the sound of recorded videos.

Relation to AI

Which? Tested the tools directly, so the sound that it judged was the tools' own output. It compared the three phones with one another and did not compare the tools with manual audio editing. The article presents the tools among the phones' AI features and does not describe the models behind them.

Follow-up

Conditions for replication

The tools work on video recordings with speech and background noise.

Entry details

Sector

Consumer technology (video sound editing).

Purpose

Apple, Google and Samsung built their audio tools to reduce background noise in videos and make speech clearer.
