A speech synthesizing system producing a speech of an improved quality of voice by selecting a combination of speech segment most suitable for a synthesis speech unit sequence. The speech synthesizing system comprises a speech segment storage section where speech segment is stored, a speech segment selection information storage section where speech segment selection information including combinations of speech segment constituted of speech segment stored in the speech segment storage section for an arbitrary speech unit sequence and the appropriateness information representing the appropriatenesses of the combinations are stored, a speech segment selecting section for selecting a combination of speech segment most suitable for a synthesis parameter according to the speech segment selection information stored in the speech segment storage section, and a waveform generating section for generating speech waveform data from the combination of speech segment selected by the speech segment selecting section.
