an operation of the second embodiment the pitch defining unit 20 defines pitch of prosecuted frame data based on the musical note from the performance data storage unit 11 and outputs the result to the voice synthesis unit selector 12 the voice synthesis unit selector 12 reads articulation data and stationary data which are the closest to the defined pitch and phoneme information in lyrics information the later process is the same as that of the first embodiment the singing voice synthesizing apparatus according to a third embodiment of the present invention is explained based on fig6 fig6 a to 6c are a block diagram of the singing voice synthesizing apparatus and an example of a phoneme database according to the third embodiment an explanation for the same parts as the first embodiment is omitted by giving the same symbols one of differences from the first embodiment is that an expression template selector 30 a to select an appropriate vibrato template from an expression database is equipped based on an expression database 30 in which vibrato information and the like are stored and expression information in performance data in addition to the phoneme database 10 also the pitch defining unit 20 defines pitch based on vibrato data from musical note information performance data and the expression template selector 30 a as for an operation of the third embodiment reading articulation data and stationary data from the phoneme database 10 in the voice synthesis unit selector 12 is same as the first embodiment based on the musical note from the performance data storage unit 11 the later process is the same as that of the first embodiment on the other hand the expression template selector 30 a reads the most suitable vibrato data from the expression database 30 based on expression.
