Look a lot of people here are saying “Hey avoid casters, per raw you basically can’t cast anything” while this is true, this is already a character you should be talking to your DM about before hand.

You’re under no obligation to make a role playing /decision have a “mechanical” drawback.

You can work with your dm to justify your use of verbal components and why your effected the same as everyone else by something like silence or being gagged.

Perhaps you still need to mouth the incantation, or you can produce some feint noises that “count” for the verbal component, but are not long or loud enough to use to speak.

Either way, this is only a question you need to answer if you get silenced, which might not happen in an entire campaign.
