Claim:
A non-transitory computer-readable recording medium that stores a computer program for reproducing a specific part of recorded sound, wherein the computer program causes a computer to execute operations comprising: creating a structure of the recorded sound by analyzing the recorded sound, the structure including a tree structure with a plurality of nodes, wherein the nodes include a first node, a second node and a third node, the first node being determined as an utterance of one person based on power of sound included in the recorded sound wherein an utterance tag is determined for the first node based on a result of voice recognition, the second node including a pair of first nodes wherein pairing of first nodes is determined based on a predetermined pairing of utterance tags determined for first nodes, the third node including at least a first node or a second node and being determined based on a pause length between first nodes, a pitch change between first nodes, a power pitch change between first nodes and a result of voice recognition; displaying the structure of the recorded sound on a display; receiving a request for reproducing a first part of the recorded sound from a user, the user specifying the first part in the structure of the recorded sound displayed, the first part including the first node, the second node or the third node; determining a second part of the recorded sound, based on the request and the structure of the recorded sound, by including, in the second part, any one of a brother node of a node corresponding to the first part and a parent node of the node corresponding to the first part; and reproducing the second part.
