The method includes: obtaining a first pitch parameter for a current time; obtaining a historical second pitch parameter in a predetermined time period before the current time; determining an updated threshold based on the obtained historical second pitch parameter; comparing the first pitch parameter for the current time with the determined updated threshold; and updating the first pitch parameter for the current time based on a result of the comparison.
