    Parametric representation of speech prosody. According to the source-filter theory of speech production (Fant, 1981), a speech waveform can be represented as a convolution of the excitation signal (source signal) and the vocal tract filter. The excitation signal is either the vibration produced by the vocal fold or the noise produced in various ... State-of-the-art statistical parametric speech synthesis (SPSS) generally uses a vocoder to represent speech signals and parameterize them into features for subsequent modeling. Magnitude spectrum has been a dominant feature over the years. Although perceptual studies have shown that phase spectrum is essential to the quality of synthesized speech, it is often ignored by using a minimum phase ...

    Statistical Parametric Speech Synthesis

    niques in statistical parametric speech synthesis. Although many research groups have contributed to progress in statisti-cal parametric speech synthesis, the description given here is somewhat biased toward implementation on the HMM-based speech synthesis system (HTS)1 (Yoshimura et al., 1999; Zen et al., 2007b) for the sake of logical coherence. While training an acoustic model for statistical parametric speech synthesis (SPSS) [1], a set of parametric representation of speech (e.g. cepstra [2], line spectrum pairs [3], fundamental frequency, and aperiodicity [4].) at every 5 ms is first extracted then relationships between linguistic features associated with the speech waveform and speech synthesis methods are not capable of yielding as good speech quality as the best unit selection techniques. This stems mainly from three causes [2, 3]: First, the parametric representation of speech, the process called vocoding, is unable to represent the speech waveform adequately hence resulting in robotic quality and buzziness. Second,

The drawback of this approach is that it is ... Abstract: A vocoder is used to express a speech waveform with a controllable parametric representation that can be converted back into a speech waveform. Vocoders representing their main categories (mixed excitation, glottal, and sinusoidal vocoders) were compared in this study with formal and crowd-sourced listening tests. Various parametric representations have been proposed to model the speech signal. While the performance of such vocoders is wellknown in the context of speech processing, their extrapolation to singing voice synthesis might not be straightforward. The goal of this paper is twofold.
