Abstract
A method for slowing a digital audio signal from the transmitter in order to transmit a slowed-down digital audio signal to a receiver, comprises the conversion of the digital audio signal received from a transmitter into a text made up of a series of words, assigning a timestamp bookmark to each word of the text, identifying words that belong to patterns referenced in a database of patterns to be eliminated, the definition of a rate of slowing, the adaptation of timestamped bookmarks to a slowed-down time frame based on the time of slowing, the slowing of the digital audio signal, the deletion of patterns to be eliminated, and the transmission to the receiver of a slowed-down digital audio signal.
