Working with IVR Systems
Testing IVR performance for speech quality and prompt accuracy can be performed by a MultiDSLA system.
Measure Music Quality using ITU PEAQ
Many devices, including cellphones, now have mp3 players or similar music replay capabilities. Assessing the quality of the replay is important in product development, production and a factor in cellphone selection. Here’s how to do it with MultiDSLA.
Measure cellphone mp3 audio performance
MultiDSLA is well known for its speech-based measurements but it also supports the tone-based and other measurements used traditionally to assess telephony performance. These features are contained in the Telephone Tester option and can now be used with a 48k sample rate DSLAII to measure the performance of music playback.
Calibrate levels for optimum MOS
In this how-to we explain how adjusting the level at which we run the test significantly influences the measured speech quality of the connection.
Monitor a DSLA test call and terminate the call if a tone is detected
A recent request we received to monitor a call and terminate it if, at any time, a tone is detected on the call.
Programmatically start a test in 5 easy steps
MultiDSLA includes a programmable interface to control the configuring and scheduling of tests along with the extraction of results. This tutorial demonstrates how simple it is to get started.
