For great results in the least amount of time, I think and feel it is best to combine real speech or synthetic speech with vocal-oriented post-processing, and perhaps a bit of other oddness, e.g., ring-mod, mixed in at low level in parallel.

So:

Apple Text-to-Speech --or-- real human voice --> (Vocoder) --or-- (Formant/PitchCorrect) --> (Synthy Mangling) --> (Added parallel Synth tones)
