    • A filter such as a Wiener filter for noise reduction in a signal, such as a speech signal, affected by background noise includes a circuit (50) for determining values of an update function relating new value of estimated noise power (P noise-New ) to a previous value of estimated noise power (P noise ), the update function being a function of said previous estimated noise power (P noise ) and a mean input power spectral density (P IN-PSD ). The circuit (50) includes a look-up table (30) having values for the update function stored therein with the previous value of estimated noise power (P noise ) and the mean input power spectral density (P in _PSD ) as a first and a second search entry, respectively. These search entries are entered via an input module (10) and exploited by search circuitry (12 to 28) associated with the look-up table (30) for selectively searching values for the update function in the look-up table (30). The search is preferably carried out on the basis of an index (26) computed starting from said first and second search entries.

The emotional recognition system comprises an emotional state classifier (110) adapted to receive, during an operative phase, an input information stream (SD) with embedded information related to emotional states of a person, and to generate a succession of emotional state indications (SES) derived from said input information stream. The emotional recognition system further comprises a post-processing function (120), configured to receive at least two emotional state indications of said succession and, for each of said at least two emotional state indications, determine a corresponding emotional state representation in an emotional state representation system. The post-processing function is further configured to combine the emotional state representations of said at least two emotional state indications to obtain an output emotional state indication (OES).
