This paper argued the number of VCV instances to be recorded in the synthesis unit dictionary as well as selection methods for small scale speech synthesis system. We proposed two selection methods, i) selection method by using phonemic environmental resemblance score (PER method), ii) selection method by searching minimal LSP distance path (MLD method). We evaluated synthesized speech generated by these methods. The followings were clarified, a) improvement in quality of synthesized speech was saturated with 14, 000 VCV instances. b) There was scarcely any difference in quality of synthesized speech between PER method and MLD method through the subjective comparison test.
