@jane_jordan Ah, that would be Nicholas Briggs. He does the Dalek voices in all of the new episodes, along with the Cybermen and other aliens. As to where to start that's a difficult question to answer considering you have 60 years of content along with DW in other media. For me, because I got into the show in the mid-1980s I started out with the fifth Doctor. His stories were airing on my local PBS station and consequently my favorite era of the show is fifth and sixth Doctor but that's just me.
