I hope not. You ever try to talk at 1kHz?
For reference, middle C is about 256 Hz; most men speak
about a fifth to an octave below that, so I'd say, make
it 100-160 Hz or so for the vowels; the consonants keep
going out up to 15kHz, but I'm sure with a 4kHz cutoff,
speech should be understandable. Most women speak about
around middle C, or perhaps a fifth about that for ones
with high voices, so perhaps 500Hz.

You could also just mess around with a microphone and a
32-band equalizer. ;-)
