Some time back, I added the Speex protocol to my version of
VOCAL (www.vovida.org, VOIP tool).

Recently, I also added PESQ (automated voice quality testing
algorithm) to my tool and have been running some tests on a clean
network.  The source file is a woman reading some phrases meant
to test various aspects of codecs...

Speex has a respectable result of 3.67

Some other codecs I've tested:

g.729:    3.78
g.726-16: 1.6  (very poor quality rating)
g.726-24: 3.5
g.726-32: 3.98
g.711:    4.21

Take it easy,
