We address the issue of order identification for HMM with Poisson and Gaussian emissions. We prove information theoretic BIC-like mixture inequalities in the spirit of (Finesso 1991), (Liu & Narayan 1994) and (Gassiat & Boucheron 2003). These inequalities lead to consistent penalized estimators that need no prior bound on the order nor on the parameters of the mixture components.
