1. An apparatus, comprising: an audio corpus; transcription data corresponding to the audio corpus; automatic speech recognition logic coupled with an associated interface for receiving the audio corpus and the associated interface for receiving transcription data; wherein the automatic speech recognition logic is operable to analyze the audio corpus and the transcription data corresponding to the audio corpus to determine a plurality of speaker clusters corresponding to a plurality of speaker types from the audio corpus and the transcription data corresponding to the audio corpus; wherein the automatic speech recognition logic is trained for each speaker cluster belonging to the plurality of speaker clusters; wherein the automatic speech recognition logic is operable to determine a selected speaker cluster selected from the plurality of speaker clusters for an associated source responsive to receiving audio data and a transcription of the audio data from the associated source; and wherein the automatic speech recognition logic employs the selected speaker cluster for transcribing the audio from the associated source.
