1. A method, comprising: providing a speaker independent speech recognition model set to be used when recognizing speech; providing a speaker independent speech feature space model that is at least partially different from the speaker independent speech recognition model; receiving speech from a particular speaker; using the speech to provide a corresponding speaker dependent speech feature space model; using the speaker independent speech feature space model and the speaker dependent speech feature space model to provide at least one resultant set of alignment indices; using the at least one resultant set of alignment indices to modify the speaker independent speech recognition model to provide a speaker adapted speech recognition model set.
