Your skepticism is justified here. This is one of those cases where AI Overview sounds extremely polished while quietly smearing together:

• a real phenomenon,
• partial truth,
• overgeneralization,
• and concierge-hotel phrasing 😂

The:

「他にもお探しの意味・情報が異なる場合は、お気軽にお知らせください」

absolutely sounds like:

“Our staff remains at your disposal regarding additional cloth-related inquiries.”

Meanwhile the poor user just typed:

“ふきんい”

AI Overview has the energy of a receptionist who refuses to admit confusion.

Now, about:

雰囲気 → ふんいき vs ふいんき

This is a real phenomenon. But AI Overview presented it too confidently and too universally.

The actual situation:

• ふんいき = standard pronunciation
• ふいんき = very common metathesis / sound swap

And yes:

many native speakers genuinely say ふいんき naturally

Not as a joke.
Not as slang.
Not to be funny.

It’s a real spontaneous pronunciation shift.

---

Why does it happen?

Because:

んい sequence is awkward

So brains/mouths tend to reorder:

• ふんいき
  → ふいんき

This kind of sound transposition is very common in human language generally.

English examples:

• “ask” → “aks”
• “comfortable” → “comfterble”
• “prescription” → “perscription”

Not stupidity.
Not illiteracy.
Just speech optimization goblins at work.

The important nuance AI missed

AI Overview says:

“many native Japanese speakers say ふきんい”

But:

❌ ふきんい

is NOT the common variant.

The common variant is:

✔ ふいんき

Your second screenshot hilariously demonstrates this failure.

You searched:

“ふきんい”

And Google went:

“Ah yes perhaps you seek 不均一 or 布巾.”

That’s because:

• ふきんい is not really established as a pronunciation
• AI accidentally overgenerated the wrong metathesis pattern

This is EXACTLY the kind of thing that makes AI Overview funny:
it speaks with concierge confidence while slightly hallucinating the hallway.

---

Does “nobody actually says it”?

No, lots of people genuinely say:

ふいんき

In fact:

• many native speakers don’t notice they do
• some think it is the correct pronunciation
• dictionaries even mention it because it’s so widespread

But:

ふきんい

would sound bizarre to most Japanese ears.

That’s the crucial distinction AI blurred.

---

The deeper funny thing here

AI Overview is trying to imitate:

• NHK pronunciation guide
• friendly tutor
• hotel concierge
• search assistant
• encyclopedia

all simultaneously.

So you get this uncanny tone:

“Indeed, honored guest, metathesis phenomena are occasionally observed among the natives. Furthermore, should your towel-related interests persist, I remain available.”

It’s genuinely entertaining.

About the broader pitch-accent / pronunciation wars

This also connects beautifully to your earlier skepticism.

Because AI systems often treat language as:

one correct canonical form + deviations

But real speech is:

• probabilistic
• lazy
• optimized
• socially adaptive
• full of mergers and shortcuts

Native speakers constantly:

• reorder sounds
• flatten pitch
• contract syllables
• skip particles

while still communicating perfectly.

---

Final verdict

• ✔ ふんいき = standard
• ✔ ふいんき = very common real-world variant
• ❌ ふきんい = AI confusion / overcorrection
• ✔ Your skepticism = healthy
• ✔ AI Overview concierge tone = unintentionally hilarious

And honestly, your phrase:

“it sounds like a hotel concierge”

is now permanently how I will internally hear AI Overview Japanese 😭
