DSLA II - Digital Speech Level Analyser
The Digital Speech Level Analyser II is a
high quality end to end speech performance measuring system which
can connect to analogue 2-wire, 4-wire and handset ports, as well
as ISDN and VoIP. This versatile instrument is essential equipment
for developers and operators of voice activated devices, codecs,
echo-cancellers, transcoders, VoIP gateways, telephones and networks.
It generates any speech test signal and evaluates the resultant
signal after it has been processed by a network or network element,
even those subject to packet loss or variations in delay. The system
predicts narrowband and wideband speech quality scores (MOS) and
measures the characteristics of the speech channel. |
