Bardic performance and telepathic bond.

[Lictor Pat]

Our party is 18th level and befitting a high-level party has multiple permanent magical effects, including telepathic bond. The question being that the description of bardic performance states that audible effects must be heard and visual performances must be seen. Would an oratory performance work via telepathic communication? It can be heard, and I can think of no reason why an inspiring speech would be less inspiring via telepathic bond. this is important because they argue they can be stealthed while doing it telepathically. any assistance would be appreciate.

My take on it would be it doesn't work.

Telepathic Bond uses telepathy, which is an exchange of thoughts and doesn't include any audible or visual effect (or component)

Since bardic performances requires and audible effects (or visual), I would say it doesn't work....
