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.
Claims10
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, and
- transmitting a slowed-down digital audio signal to the receiver.
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.
An apparatus, comprising:
- means for converting a digital audio signal received from a transmitter into a text composed of a series of words,
- means for assigning a timestamp bookmark to each word in the text relative to an absolute time reference,
- means for identifying words that belong to patterns referenced in a database,
- means for defining a rate of slowing based on the patterns to be eliminated deduced from the database,
- means for adapting the timestamp bookmarks to a slowed-down time frame based on the rate of slowing,
- means for slowing down the digital audio signal,
- means for deleting the patterns to be eliminated from the digital audio signal, and
- means for transmitting a slowed-down digital audio signal to a receiver.
