What is the optimum Sample Rate and Bit Rate for human voices in an MP3 file?

Is 22050 Hz, 64 kbps a suitable choice?

64kbps is a good bit rate, but experiments I've done indicate that 44100 Hz is the (marginally) better sample rate.

The professional delivery standard is mono, 44,100, 128kbps.

We should have asked the question "optimal for what purpose?" 128kbps is certainly better than 64kbps, but may result in a larger file than you'd like for a podcast, for example.
