Blind Source Separation (BSS) arises in a variety of elds in speech processing such as speech enhancement, speakers diarization and identi cation. Generally, methods for BSS consider several observations of the same recording. Single microphone analysis is the worst underde- termined case, but, it is also the more realistic one. In this article, the autoregressive structure (short term prediction) and the periodic signa- ture (long term prediction) of voiced speech signal are modeled and a linear state space model with unknown parameters is derived. The Expec- tation Maximization (EM) algorithm is used to estimate these unknown parameters and therefore help source separation.
