1. A method for processing speech, comprising: receiving a speech signal of a speaker; generating speech parameters from said speech signal; determining a distance of the speaker based on a time delay of a respective arrival of said speech signal at two or more microphones; normalizing a measured loudness or energy by said distance; calculating an absolute loudness being a loudness of a speech that generated the speech signal at a location of a source of the speech; and evaluating at least one of said speech signal and said speech parameters using the normalized loudness or energy to identify the speaker.
