Changelog

1.1.1

Fixed nickname resolution. Some players were showing as Player 9 / Player 23 instead of their real nicknames. The voice subsystem uses a separate Photon room with its own actor numbering, so feeding the voice playerId straight into Room.GetPlayer() resolves the wrong player (or no one).
The fix reads the PhotonView ID that PUN packs into VoiceInfo.UserData (this is the same hint PunVoiceClient.InstantiateSpeakerForRemoteVoice uses to link a Speaker to a player), and derives the real game ActorNumber from it (PUN's standard viewID = actorNumber * 1000 + viewNumber layout). Falls back to the voice playerId only if UserData is missing.

Loudness filter: quiet background noise (passing the open-mic threshold but contributing nothing) no longer pollutes the list. Only real speech registers.
Loud shouters in red: anyone speaking above the loud threshold is highlighted in bold red and stays visible for 3 seconds, so a sudden shout pops out from the always-on chatter.
F8 toggles the overlay. A faint [F8] Mic Snitch hint stays in the corner when hidden, so the hotkey is never forgotten.
Sort order: loud speakers on top (most recent first), then normal-volume speakers below.
Smaller, semi-transparent text — readable but not in your face when 10 people are on a loading screen.
Internal: dropped the redundant Speaker.OnAudioFrame / VoiceClient.onFrame / Transport.onVoiceFrameEvent hooks; everything now flows through RemoteVoiceLink.OnDecodedFrameFloatAction which fires for every decoded voice (init-broken or not) and gives access to the audio samples for the loudness analysis.

Initial release.
Shows nicknames of currently-talking players in the upper-right corner.
Hooks LoadBalancingTransport.onVoiceFrameEvent so detection works even when other players' cosmetic mods break Speaker initialization.
Local mic detection via LocalVoice.IsCurrentlyTransmitting — shows your own name too.
All game/Photon types resolved via reflection for forward-compatibility.
