9. The system of claim 8 , wherein the non-linear phase-sensitive model of additive and convolutive distortions is represented as follows: = x + h + C ⁢ ⁢ log ⁡ ( 1 + exp ⁡ ( C - 1 ⁡ ( n - x - h ) ) + 2 ⁢ α · exp ⁡ ( C - 1 ⁡ ( n - x - h ) 2 ) ) ⁢ = x + h + g α ⁡ ( x , h , n ) , where g α (x, h, n)=C log(1+exp(C −1 (n−x−h)+2α·exp(C −1 (n−x−h)/2)), where y, x, n, and h are vector-valued distorted speech, clean speech, additive distortion, and convolutive distortion in the received distorted speech utterance, respectively; C is a non-square discrete cosine transform (DCT) matrix; C −1 is an inverse DCT matrix; and α=[α (1) , α (2) , . . . α (l) , . . . α (L) ] T is a phase-factor vector for L Mel filter banks.
8. The system of claim 1 , wherein the adaptor component receives joint estimates of additive and convolutive distortion from a non-linear phase sensitive model of additive and convolutive distortion, and wherein the adaptor component adapts parameters of at least one compressed model in the plurality of compressed models based at least in part upon the joint estimates of additive and convolutive distortion.
