The supply of vowel audio data is stopped at tα (when tα has elapsed).

The speech synthesizer 5 receives consonant speech data, vowel speech data, and pitch data l)+ which are supplied in a timely manner.
The system synthesizes sounds corresponding to musical scales based on the following. The output data of the speech synthesizer 5 is supplied to a digital-to-analog converter (hereinafter abbreviated as a D/A converter) 10. The output signal of the D/A converter 10 is supplied to an amplifier 11.

On the other hand, reference numeral 13 denotes a keyboard, and key switches are provided corresponding to each part of the keyboard 13, and the outputs of these key switches are both supplied to a key press detection circuit 14.

The pressed key detection circuit 14 detects the pressed key on the keyboard 13.
It is detected based on the output of the key switch, and pitch data D3 corresponding to the same key is output to the musical tone forming circuit 6. The musical tone forming circuit 6 forms musical tone signals corresponding to the pitch data DI and I)s, mixes the formed musical tone signals, and supplies the mixed signal to the amplifier 11-\. The amplifier 11 mixes and amplifies the output of the musical tone forming circuit 6 and the output of the D/A converter 10, and supplies the mixed signal to the speaker 12. As a result, both musical tones and voices are produced from the speaker 12.

Next, the operation of this embodiment will be explained based on FIGS. 1 to 3.

First, when the operator causes the reader 1 to read the card A on which musical tone data of a musical piece shown in FIG. 2 is written, for example, this musical tone data is stored in the musical tone data storage section 2. Table 1 shows the storage state of the musical tone data storage section 2 at this time.

Table 1 As shown in this table, pitch data and note length data are stored in order starting from address "0O01". and.

Next, when the operator presses a start switch (not shown), the data read control s7 sends the timing signal S to the consonant data transfer control section 9. It supplies address data [oooIJ] to the vowel data transfer control section 8 and also to the musical tone data storage section 2. The musical tone data storage section 2 is stored at the specified address [0001
