Patent ID: 8059794

Claim:
A sound data providing system comprising a sending terminal that sends sound data, a user interface, an exchange and a receiving terminal that receives the sound data, which are connected to one another, wherein: the sending terminal includes: a sound data input section that inputs sound data; a various information transmitter that transmits to the user interface various information on the sound data input through the sound data input section; a destination information transmitter that transmits to the user interface destination information that specifies the receiving terminal where the input sound data is to be provided; and a date information transmitter that transmits to the user interface date information that specifies the date of delivery of the input sound data to the receiving terminal; the user interface includes: a related information generator that generates related information compatible with the exchange based on the various information, destination information and date information received from the sending terminal; and a related information transmitter that transmits to the exchange the related information generated by the related information generator; the exchange includes: a sound data synthesizer that synthesizes the sound data based on the various information on the sound data extracted from the related information received from the user interface; a destination specification section that specifies the receiving terminal where the sound data is to be provided based on the destination information extracted from the related information received from the user interface: a date specification section that specifies the date of delivery of the sound data based on the date information extracted from the related information received from the user interface; and a sound data delivery section that delivers the sound data created by the sound data synthesizer to the receiving terminal at the specified date; and the receiving terminal includes: a sound data acquisition section that receives the sound data from the exchange; and a sound data output section that outputs the sound data received by the sound data acquisition section, wherein: the exchange further includes a data acceptance determination section that inquires whether or not the receiving terminal accepts the sound data to determine whether or not to provide the sound data thereto based on data acceptance information received therefrom as a response to the inquiry; the receiving terminal further includes a data acceptance information transmitter that transmits to the exchange the data acceptance information as to whether or not to accept the sound data; and at least any of the exchange and the receiving terminal further includes a reception refusal determination section that determines whether or not the sound data is acceptable based on identification information of terminals preset in the receiving terminal from which the sound data is to be refused.
