Can you tell me how you can tell someone casting a spell from someone asking for his granny if both are whispering? If you can tell me how it is logically done when the PC can't read lips, I'll concede the point. Otherwise you've lost this.You are homebrewing the above requirement.
The Counterspell has a spell effect that can affect any visible spellcaster.
This is wrong. Once the effects are apparent the spell is done and cannot be countered. You must interrupt the casting which has no visible effects until finished.The power of the spell description is to target and deflect, even after the target is in the process of casting and the effects of the casting are apparent.
Counterspell gives no ability to read lips.Counterspell is a magical spell and can literally do anything. Because magic.
Just like someone whispering for granny.If a spell is verbal-only, people can see the lips moving, throat tensing, concentration, and so on.
This is objectively wrong. You must comprehend that a spell is being cast. That is RAW.Counterspell only requires visibility. Not comprehension.
