This paper introduces the Toshiba Mandarin Text-to-Speech (TTS) system submitted to the Mandarin benchmark of the Blizzard Challenge 2009.The basic framework keeps unchanged with the system in 2008 and we modify the system in several aspects: automatically find bad units in the database when preparing the speech corpus, add a G2P procedure after the text analysis to increase accuracy of the predicted pinyin for heteronyms 1 , introduce prosody layer information into the prosody modeling and modify the fusion methods to fuse units in frequency domain.The subjective evaluation results show that these modifications improve the performance.
