Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we investigate the statistical voice conversion (VC) under noisy environments.
VC achieves conversion from input speech to target speech by statistically modeling correspondence between input and target acoustic features.
To develop various VC applications, such as augmented speech production and augmented vocal production, it is necessary to handle noisy input speech because various background sounds, such as external noise and accompaniment, usually exist in a real environment.In this report, we investigate an impact of background sounds on conversion performance in singing voice conversion focusing on a vocoder-based conversion method and a vocoder-free conversion method based on direct waveform modification with log-spectral differential compensation (DIFFVC).Results of subjective evaluation show that DIFFVC is robust against background sounds compared with the vocoder-based conversion method.We also analyze the robustness of DIFFVC using a kurtosis ratio as an objective metric to evaluate distribution changes of power spectral components.
