HEARING ASSISTANCE DEVICE WITH FUNDAMENTAL FREQUENCY MODIFICATION

摘要

The invention relates to a hearing assistance device comprising a frequency analyzing device which is configured to determine a current fundamental frequency value of a speech signal for a period of time of the speech signal. A statistical analyzing device is configured to determine an average fundamental frequency value of the speech signal over multiple periods of time. The hearing assistance device further comprises a fundamental frequency modifier which is configured to modify the current fundamental frequency value into a modified fundamental frequency value such that a difference or a quotient between the current fundamental frequency value and the average fundamental frequency value is changed according to a specific function. In this manner, a frequency range can be changed within which the fundamental frequency value varies. The hearing assistance device further comprises a speech signal generator which is configured to generate a speech signal that is modified with respect to the fundamental frequency on the basis of the modified fundamental frequency value.
