    Pitch Marks at Peaks or Valleys?

  • Original language description

    This paper deals with the problem of speech waveform polarity. As the polarity of speech waveform can influence the performance of pitch marking algorithms, the simple method for the speech signal polarity determination is presented in this paper. We call this problem peak/valley decision making, i.e. making of decision whether pitch marks should be placed at peaks (local maxima) or at valleys (local minima) of a speech waveform. Besides, the proposed method can be utilized to check the polarity consistence of a speech corpus, which is important for the concatenation of speech units.

    Hlasivkové pulzy v maximech či minimech?

  • Czech description

    V tomto článku se zabýváme problémem polarity řečového signálu a jejího vlivu na přesnost umísťování hlasivkových pulzů v řeči. Byla navržena jednoduchá metoda pro určení polarity řečových signálů, která může být použita pro kontrolu konzistence řečovéhokorpusu.
