I think the chosen maincharacter absolutely should speak every sentence in the final version.
Why? Because everyone else does. All those NPC's.
And of course the party-characters too sometimes as they bring themself in.
Don't forget that we are free to play the "partymembers" as maincharacter in the final version.
It would be absolutely awkward if they are more of a mute if played as main, as when they would be just a partymember.
But it breaks immersion and forces a personality on me that I don't want. Give me the option for a silent protagonist, seriously. It costs NOTHING for Larian to give me this option.
Just imagine if we get to play a half-orc or a lizardfolk and they have this posh british accent. It's going to be so cringe.
