Abstract (en)
[origin: EP1130577A2] The method involves determining at least two adjacent frequency components in the speech signal with increased amplitude above a frequency threshold (w0). The fundamental frequency (wg) of the speech signal is determined as the difference between the two or more adjacent frequency components and the low frequency range is reconstructed below the threshold frequency using the determined fundamental frequency. Independent claims are also included for the following: (1) the use of the method in a moving vehicle (2) an arrangement for reconstruction of low frequency speech components.
