The actress whose voice that I find cheerful, friendly and often a bit ditzy is Lurene Tuttle - first became aware of her as a character in Sam Spade and then realised that she appreared on so many other programmes. But I find Agnes Moorehead's voice irritating most of the time, though to her credit, I think that was often the effect that was sought - but for me it can be like fingernails on a blackboard. And the actor's voice that I'm not particularly fond of (and a choice that may not make me many friends) is that of Orson Welles. I find his voice a bit smug at times and to me it seems that most of the time he is over acting - hard to lose yourself in the character because you always know it is Orson Welles the actor.
