基於時域上基週同步疊加法之歌聲合成系統 (Singing Voice Synthesis System Based on Time Domain-Pitch Synchronized Overlap and Add) [In Chinese]

In this study, we propose and implement a concatenation-based singing synthesis system to synthesize the singing voice with background music. We record three different pitches to build our corpus for all syllables. The synthesis informations, including velocity, note number, start time and end time are extracted from the main melody. Runs and riffs information was added into consideration afterward. We use TD-PSOLA to modify the synthesis units in time domain. At last, we add back the background music extracted from MIDI to our synthesis song. We implemented a user interface for users to synthesize songs. This interface can be used to adjust the synthesis songs, for example, adjust the overall pitches in the song, modify syllables, etc. Finally, we evaluate the quality, clarity and similarity of the synthesis songs. The results show that the proposed method achieve better results with simple songs than with fast songs. keywords: concatenation synthesis, singing synthesis, TD-PSOLA Proceedings of the Twenty-Fifth Conference on Computational Linguistics and Speech Processing (ROCLING 2013)
