ETSI TR 126 935 provides information on the performances of default speech codecs in packet switched
conversational multimedia applications. The codecs under test are AMR-NB (Adaptive Multi-Rate Narrowband) and
AMR-WB (Adaptive Multi-Rate Wideband). In addition, several ITU-T codecs (G.723.1, G.729, G.722 and G.711) are
included in the testing. Experimental test results from the speech quality testing are reported to illustrate the behaviour
of these codecs.
The results give information of the performance of PS conversational multimedia applications under various operating
and transmission conditions (e.g., considering radio transmission errors, IP packet losses, end-to-end delays, and several
types of background noise). The performance results can be used e.g. as guidance for network planning and to
appropriately adjust the radio network parameters.
