Through the use of subband analysis, the article presents a method for selecting pauses in speech communications. An additive blending of normally distributed noise was used in the sensitivity analysis. In various noise / signal respects, the probability of making a bad decision has been identified. The findings show that the proposed sub-band method is stable when subjected to additive noise effects.
