What have neural networks achieved?

[Dr. Khalid Al-Mashouq]

I am part of ACES (http://www.riyadhweb.com/aces) , a
telecommunications and electronics company based in Saudi
Arabia. Recently we sold Lucent Technology (AT&T, formerly) a
multi-million system to test the Saudi GSM mobile network quality on
the voice level (not bit-error rate level).  This system is made by
ASCOM (http://www.ascom.ch/qvoice) and worldwide accepted. It uses the
neural network-fuzzy techniques to assess the quality of the received
voice signal without paying the overhead of sending real people in the
field to measure the quality. As ASCOM puts it:

     Using advanced neural networking technology, the
     fully automatic system is trained to map speech
     patterns, and to produce quality ratings which
     correlate over 98% to those produced "unconsciously"
     by the combination of the human ear and brain.

(For technical details about this system and other related systems,
see http://www.ascom.ch/qvoice/qos/qqos0000.htm and

Hope this information is useful.
