音節データＡ１と音節定義情報Ａ２が格納されている。Next, the operation of the speech synthesis apparatus shown in FIG. 2 when synthesizing speech will be described. It is now assumed that audio data A, D, and E are read out from the external storage device 1 in this order. First, audio data A is read from external storage device 1 and stored in auxiliary storage device 2 . FIG. 3 shows voice data A stored in the auxiliary storage device 2, in which valid syllable data A1 and syllable definition information A2 are stored.

1, final address &2, and silent time data La, and convert them into valid data AI' and silent data A2', which are analog signals, and output them, respectively. FIG. 4 is an explanatory diagram showing the output state of valid data AI' and silent data A2', and silent data A2' is output after valid data AI'. Therefore, the speaker 5 remains silent for a predetermined period of time (time corresponding to In) following the generation of the sound of the valid data AI'.

While ' is being formed in the speech synthesizer 4, subsequently...
Syllable data D is read from the external storage device 1 and stored in the auxiliary storage device 2 as shown in FIG. Arithmetic device 3
is valid syllable information D, just as in the case of syllable data A.
The first address d1 and the last address d2 of 1 are found, the silent time data Ld is found from the syllable definition information A2, and after receiving the report of the output end of the syllable data A, the speech synthesizer 4
Output to. The speech synthesis device 4 receives the first address di, the last address d2, and the silent time data Ld, converts them into valid data DI' and silent data D2' of analog signals, and outputs the converted data. Therefore, as shown in the fourth factor, the speaker 5
After the silent state (based on the silent data A 2'), the sound generation of the valid data DI' is performed, and the state becomes silent again (based on the silent data D 2'). From then on,
A similar operation is performed for the syllable data E as well.

ら発生することができる。As is clear from the above description, according to the present embodiment, the syllable data stored in the external storage device l is divided into effective syllable data indicating the generated sound and syllable definition information indicating the silent time, and is composed of dinotal signals. However, since the silent data is not directly included in the syllable data, the amount of syllable data can be reduced. Therefore, it becomes possible to downsize the external storage device l. Furthermore, even without a configuration in which silent data can be directly played on the syllable r-y, smooth continuous sounds can be generated from the speaker without damaging the connections between syllables.

The amount of syllable data can be reduced without impairing the smoothness of speech synthesis, and as a result, the external storage device can be downsized.
