An electronic musical apparatus is designed to sing a song based on performance data which indicate a melody originally played by a musical instrument. Herein, the apparatus contains a formant tone generator and a data memory which stores a plurality of formant data, lyric data and melody data. Formant synthesis method is employed for voice synthesis to generate voices based on the plurality of formant data selectively designated by the lyric data so that the voices are sequentially generated in accordance with words of a song. Thus, the song is automatically swung by sequentially generating the voices in accordance with a melody which is designated by. the melody data; and the voice synthesis is controlled such that generation of the voices temporarily stopped at timings of pausing for breath. Moreover, the data memory can store formant parameters with respect to each phoneme, so that the formant tone generator can gradually shift sounding thereof from a first phoneme (e.g., a consonant) to a second phoneme (e.g., a vowel). Herein, formant parameters, regarding the first phoneme, are supplied to the formant tone generator in a pre-interpolation time between a first phoneme sounding-start-time and an interpolation start time. Then, Interpolation is effected on the formant parameters to achieve gradual shifting of the sounding. A pace for the shifting of the sounding from the first phoneme to the second phoneme can be changed on demand.
