What might be the case is that you'd have more trouble *distinguishing* amongst women, or between women and children, because the tones necessary for that are more located above thecutoff frequency.
Thank you for this and the link. Very interesting stuff. I have never tried to check to what extent I / others can distinguish different female / young speakers on the phone. I shall try to pay more attention to this in the future.
> In short: it depends a lot on what you mean by 'serves well'. :-)Well, just the above seems like enough that you'd think there'd be more (justified) grumbling that thanks to a choice made many many decades ago it's harder to distinguish young or female speakers than it is adult male ones. Maybe there is and I've just not noticed it. Is this one of the things pushing adoption of higher bandwidth audio codecs? (My guess: no.)
