Abstract: A method for determining intensity characteristics of background noise during speech pauses of speech signals includes determining a proportion of speech pauses in the undisturbed source speech signal so as to define a frequency threshold. The disturbed speech signal is divided into short successive signal elements, an intensity value is determined for each of the signal elements, and a cumulative relative frequency distribution is formed from the determined intensity values of the signal elements. The cumulative relative frequency distribution is used to determine an intensity threshold value which corresponds to the defined frequency threshold. At least one intensity characteristic of the background noise during the speech pauses is determined using a region of the cumulative relative frequency distribution below the intensity threshold value.

Abstract: In a method for determining speech quality using an objective measure, in order to enhance prediction reliability of the evaluated quality parameters, distortions of the mean spectral envelope are extensively corrected with a weighting function WT(f) before comparing spectral properties. Additionally, the fixed band limits for integration of spectral power density are suppressed and other band limits are searched for instead in a predetermined optimization area in which the resulting spectral intensity representations of the voice signal to be evaluated and the reference voice signal have maximum similarity. The solutions described can supplement known methods and can be incorporated into their structures.

Abstract: Known methods for determining intensity parameters are based on the evaluation of short signal segments and their direct allocation to speech pauses or speech activity. In order to distinguish speech from speech pauses, intensity thresholds are often used. When the undisturbed source signal is used to mark, speech pauses, a variably occurring time lag between source voice signal and disturbed voice signal often impedes exact transfer of the marking. Intensity parameters of background noises in speech pauses can be determined from the frequency distribution of the intensity values for short signal segments using the method disclosed in the invention. In order to assign intensity values, the fraction of speech pauses in the entire signal is calculated from the undisturbed source signal and defined as frequency threshold. Intensity values below the frequency threshold are assigned to the speech pauses.
