Abstract: The quality of speech, or important speech parameters such as the intelligibility, clearness or naturalness of speech, can be emphasized by signal processing. Such processing for improving speech quality can be found in telecommunication applications, e.g. mobile telephony, internet telephony or personal intercom. Blind methods are preferable over conventional because they do not require calibration schemes and are independent of environmental variations. By careful selection of hardware domain for realization, i.e. digital, analog, or hybrid, implementation-specific benefits can be utilized to increase the speech quality or performance. This report stresses some implementation aspects when implementing a blind method for speech enhancement in digital, analog, and hybrid digital-analog hardware.
