AI noise removal uses a model trained on many examples of speech and noise. It estimates which parts of a recording are speech and which are background, then reduces the background. It does not understand the words, so it can remove sounds that are not noise, or leave noise that sounds like speech.
AI noise removal is often described as if it hears the voice and removes the rest. The reality is more practical. A model has learned patterns from many recordings of speech and noise, and it uses those patterns to decide what to reduce. Understanding that helps you judge the result.
The model looks at a short window of the recording and estimates how much of each frequency belongs to speech and how much to noise. It then reduces the parts that look like noise. Some tools also learn the noise from a sample of the room, which helps them target the background you actually have.
Because the model is estimating, it can take a little from the voice along with the noise. The most common changes are a thinner tone, a slight watery quality, and the loss of quiet breaths or soft consonants. Heavy settings make these changes stronger, so the aim is the lightest setting that does the job.
A model can mistake a sound that is part of the performance for noise, such as a laugh, a cough in a story, or a musical instrument in the background. It can also leave noise that sounds like speech, such as another voice in the room. Listen for these cases before you publish.
AI noise removal is a tool, not a guarantee. It works best on clear recordings with steady background noise. For a recording that was far away or very noisy, it will reduce the noise but may not restore the clarity. The watery sound post explains the most common side effect.

No. It estimates speech and noise from sound patterns, not from the meaning of the words.
The model reduced some of the voice along with the noise. Use a lighter setting.
Sometimes, but it may also remove parts of the performance. Check the result carefully.
They do different jobs. Noise removal reduces background, and EQ shapes tone. Many recordings use both, lightly.
