My wife has been recording the text published on the wiki. A couple of
questions for you:
1) One of the recordings says "please enter the full 10 digit number
starting with the area code". Any opinions on whether this should be
changed for the UK and, if so, to what?
2) The recordings seem "dull" on playback even though we are recording using
a good quality microphone with matching impedance. Initially we recorded
using 16 bit/8K sampling on the basis that this is what is required by
Asterisk but that was really terrible. So we're sampling at higher rates on
the basis that we can use sox to change it as necessary. Any thoughts on
what we can do to make the recordings sound "sharper"?
You can't have have sharp sounding voice over the telephone. Telephone
calls really do sound dull. We are so used to them, we tend to blot that
out of our perception. You can record at a higher sampling rate, and
then convert to 8K for final use. However, once you convert to 8K it
will still sound dull. You might use an equaliser to pep up the 2.5kHz
to 3.5kHz area a bit. That might make the perceived quality a little
better. Don't expect miracles, though.
Regards,
Steve
