[music-dsp] Is 10-bit ADC input good enough for speech?

[Augmentics]

Hi,

I have a chance to buy a cheap, used, beta-version DSP module for speech
processing ... BUT ... it has only
a 10-bit ADC in the input circuit.  [It's cheap coz the final production
version has a better ADC ... but is expensive]

So: is 10-bits enough to record the human voice "cleanly"? Or should I spend
more money?

Thanks,
