Simulation Analysis of CS-ACELP Speech Compression Algorithm Based on Mute Detection Technology

Based on the study of CS-ACELP speech compression algorithm and mute detection technology, we propose a new mute detection scheme. Based on short-time average amplitude and short-term average over zero rate, it distinguishes noise, clearing and turbidity through the two-level judgment method. Through simulation analysis, the algorithm is based on CS-ACELP algorithm proposed G.729B, it reduces the complexity and achieves the effect of reducing the code rate.
