METHOD AND DEVICE FOR SLOWING A DIGITAL AUDIO SIGNAL
First Claim
1. A method for slowing a digital audio signal received from a transmitter in order to transmit a slowed-down digital audio signal to a receiver, comprising:
- converting the digital audio signal received from the transmitter into a text composed of a series of words, assigning a timestamp bookmark to each word in the text relative to an absolute time reference,identifying words that belong to patterns referenced in a database, which allows the patterns to be eliminated to be deduced,defining a rate of slowing based on the patterns to be eliminated,adapting the timestamp bookmarks to a slowed-down time frame based on the rate of slowing,slowing down the digital audio signal,deleting the patterns to be eliminated from the digital audio signal, andtransmitting a slowed-down digital audio signal to the receiver.

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.

6. A device, comprising:
-
an input that receives a digital audio signal from a transmitter, a converter that converts the digital audio signal into a text composed of a series of words, a timestamper that associates timestamp bookmarks with each of the text'"'"'s words, a pattern database that contains the referenced patterns, wherein the reference patterns comprise words to be eliminated, a pattern recognition block that identifies the words contained in the referenced patterns and deduces the patterns to eliminate, a pattern filtering block that filters the patterns to be eliminated, a flow controller that defines a rate of slowing, a digital audio signal slower that slows the digital audio signal based on the rate of slowing, a reconstitution block that deletes the patterns to be eliminated from the digital audio signal and reconstructs the digital audio signal, and an output that restores a slowed-down digital audio signal. - View Dependent Claims (7, 8, 9)
