摘要

The method according to the invention is aimed at reducing delay-related packet losses and at increasing the quality of the speech in the event of language segment losses. DOLLAR A Based on the approach of LPC analysis and synthesis or on the model of speech generation, a concurrent estimate of the subsequently expected segment based on the previously received decoded PCM signal is made preventively. If a segment or packet loss or a segment or packet loss is suspected, the speech signal which has already been estimated in advance on suspicion can be output as a substitution without delay. DOLLAR A The method according to the invention can advantageously be used in transmission systems which are based on the packet-oriented transmission of voice signals.
