About This Item

 

Full Description

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.
