Humans use the pitch of their conversational partner as an important feature for improving the communication and the understanding especially in noisy situations. This knowledge is taken to investigate the idea of a pitch synchronous spectral analysis and a pitch dependent recognition of voiced speech segments. A first approach is presented for realizing this pitch dependent processing. Its applicability is shown for recognizing the voiced segments of the Timit database.
