I personally am not a fan of a voiced MC/PC in choice based rpgs like this. Yes, a fully voiced protag can up the overall cinematic quality or feeling of a game, but in many ways it can also restrict variety of choices to be made. Logistically speaking it is simply easier to record one side of a conversation. Therefore it's possible that a voiceless Tav actually has the potential for a wider variety of options to explore in dialogue. The game is less cinematic at times, but it's usually possible to chose wider and more divergent routes of dialogue.
I'm biased though I like to read out loud and talk to myself.
