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 methodfor controlling end-to-end latency between receiving and processing audio frames includes: receivinga data packet comprising at least one coded audio frame; storingthe received data packet in a packet buffer; retrievingthe received data packet from the packet buffer and decoding the at least one coded audio frame into audio samples; and processingthe audio samples, wherein a scheduling of retrievingthe 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.
