Updating signal typing in voice: Addition of type 4 signals

摘要: The addition of a fourth type voice to Titze’s classification scheme is proposed. This characterized by primarily stochastic noise behavior and therefore unsuitable for both perturbation correlation dimension analysis. Forty samples were classified into the proposed four types using narrowband spectrograms. Acoustic, perceptual, analyses completed all samples. Perturbation measures tended increase with type. Based on reliability cutoffs, 1 2 voices considered suitable Measures unreliability higher 3 4 voices. Correlation increased significantly signal as indicated one-way analysis variance. Notably, could not quantify represents subset dominated behavior. Current capable evaluating provide only qualitative data (spectrograms, perceptual analysis, an infinite dimension). Type are highly complex development objective analyzing these remains topic future investigation.
