Abstract
The disclosure relates to methods and devices for controlling speech quality, in particular by controlling end-to-end latency and by improving speech quality in case of mobility scenarios. A method 200 for controlling end-to-end latency between receiving and processing audio frames includes: receiving 201 a data packet comprising at least one coded audio frame; storing 202 the received data packet in a packet buffer; retrieving 203 the received data packet from the packet buffer and decoding the at least one coded audio frame into audio samples; and processing 204 the audio samples, wherein a scheduling of retrieving 203 the received data packet from the packet buffer and decoding the at least one coded audio frame is based on a target criterion with respect to audio quality of the audio samples and latency between receiving the data packet and processing the audio samples, and wherein the scheduling is dynamically and smoothly shifted in time in order to avoid audio distortions.
