Were there any public recordings or eyewitness accounts of Barron Trump using profanity toward President Biden?

1. The viral moment: a silent, ambiguous exchange

Video of Barron Trump approaching and briefly speaking into Joe Biden’s ear went viral, but the clip contains no public audio; that absence is why outlets and social media immediately turned to lip‑readers and speculation rather than witness testimony or recordings asserting profanity ^{[1] [2] [6]}.

2. No source in the record reports an audio recording of profanity

None of the collected articles cite an audio recording or an eyewitness claiming Barron said an obscenity to Biden; coverage instead emphasizes visual cues, Biden’s expression change, and conjecture — not a verified, recorded utterance of a profanity ^{[1] [2] [6]}.

3. Lip‑readers offered competing interpretations, not consensus on an insult

Forensic and amateur lip‑readers surfaced with different readings — suggestions ranged from “It’s time,” “Exactly,” to light, polite replies — but these interpretations conflict with each other and with the absence of audio, so they cannot be treated as proof of a profane remark ^{[7] [2] [6]}.

4. Family account: Eric Trump disputes the “Go F yourself” rumor

Eric Trump publicly addressed the speculation, saying Barron would not have said “go f himself” and describing the remark as courteous — he told interviewers it was something like “congratulations and best of luck to you,” a line picked up and repeated by People, Mirror, Hindustan Times and other outlets ^{[3] [4] [5] [8]}.

5. How reporting framed the moment: viral social media + media echo

Several outlets emphasized the spectacle and social‑media frenzy — highlighting Biden’s shift in expression and public guesses — which amplified rumor without producing on‑the‑record, corroborated eyewitness testimony of profanity; many pieces simply repeated lip‑reader claims or family statements ^{[1] [9] [2]}.

6. Limits of the available reporting and why certainty is impossible here

Because public footage lacks audio and no journalist‑reported eyewitness is quoted as hearing a profanity, the record cannot confirm that Barron used profanity; the only primary statements are interpretations (lip‑reading) and Eric Trump’s account — neither constitutes definitive, corroborated audio evidence ^{[2] [3] [4]}. Available sources do not mention any independent eyewitness who reported hearing an obscene remark.

7. Competing perspectives and possible incentives to shape the narrative

Family members (Eric Trump) have incentive to portray Barron politely and defuse controversy; social‑media users and some outlets gained engagement from sensational interpretations; lip‑readers can differ and be wrong without audio verification. These differing motives help explain why speculation spread quickly despite weak direct evidence ^{[3] [1] [2]}.

8. Bottom line for your question

Based on current reporting in the provided sources, there is no documented public recording or verified eyewitness account that Barron Trump used profanity toward President Biden at the inauguration; the claim rests on unverified speculation and competing lip‑reading interpretations, while a family member’s account describes a polite remark ^{[2] [3] [4]}.

If you want, I can compile verbatim quotes from the lip‑readers and from Eric Trump as presented in specific articles, or list the outlets that ran each version of the interpretation.
