Will we have voice options like in DAI. And do you want the multiple voice options

We won't, and I'm ok with that.

I think it is one voice per char. But I liked how they gave us more options in Inquisition, the female british was amazingly great! Alix Wilton Regan always gives a fantastic performances, giving a lot of fresh air to both ME(Comm Specialist Traynor) & DA(female Inquisitor and other chars in Origins and DA2) trilogies and because of that, I managed to connect with my FemQuisitor to a great extent. It was amazing

I prefer quality over quantity. Out of the four voice options in DAI there wasn't a single one I really liked to be honest. I liked both Mark Meer and Jennifer Hale in ME and Nicholas Boulton in DA2.

Tom Taylorson's voice sounds pretty good from what I've heard so far. It's deep, yet he seems to have quite a bit of range. Fryda's voice sounds a bit grating, so I'm reserving my judgement on that for now.

Multiple VAs for single characters would just cost a huge amount of money that could be better spent given us more NPCs we can really interact with or more romance-able NPCs... that is, more other characters with more voiced lines of dialogue... or better spent in doing voice overs in more other languages so that more people worldwide could play the game in their native tongue. If a player really doesn't like the VA for the main character in English, they can always try using a voice over in a different language or just turning the dialogue volume off and just read the subtitles.
