Dectalk is probably the best sounding non sampled synth. Frankly, I have great difficulty listening to the synth in the BP for more than a few minutes, it mis pronounces many things routinely. Eloquence is not too bad, it renders most words perfectly comprehensible, though the Dectalk inflections are more natural to my ear. I cannot abide Double Talk, it sounds like the robot in the original Lost in Space. Dan
