voice conversion based on Topological Feature maps and time variant filtering
International Conference on Spoken Language Processing, 1996Co-Authors: A RinscheidAbstract:Presents a new voice conversion algorithm. This algorithm allows voices to be adapted using a small amount of adaptation data. Only a few short adaptation units (phonemes or short words) are needed. The voice conversion is performed using a time-variant digital filter, Topological Feature maps and a map of filter coefficients. The filter coefficients of the time-variant filter are selected by the Feature map depending on the short-time spectrum. The spectral envelope of the input signal is modified by a time-variant filter using the selected coefficients.

proximity exchange induced gap opening and Topological Feature in graphene 1t mx2 m mo w x s se te dirac heterostructures
Journal of Physics: Condensed Matter, 2018Co-Authors: Changsheng Song, Wen Xiao, Ping Lin, Jingjing Wang, Jiaqi Pan, Can Cui, Jiqing WangAbstract:By using first-principles calculations, we demonstrate the influence of proximity effect on the band structures of heterostructures formed by graphene stacking on a two dimensional (2D) Topological insulator (TI) 1T'-MX2. The interlayer distance d between graphene and TI decreases with the enhancement of the intrinsic lattice anisotropy of 1T'-MX2, which determines different strength of the interlayer proximity interaction. The bandgap can be opened by the proximity exchange. The weak anisotropic symmetry of heterostructure (large d) only results in a small band gap (∼50 meV) in graphene/MoTe2. However, a large energy gap (up to ∼200 meV) can be obtained in graphene/MoS2, which is attributed to the inter-intralayer charge transfer due to the strong proximity interaction of the hetero-interface (small d). In addition, the 1T'-MX2 of heterostructure still possesses the Topological Feature of Z 2 = 1, since the graphene has a negligible effect on the band structure of the system.
