This paper investigates how the perceptual quality of the synthesized speech is affected by reconstruction errors in excitation signals generated by a deep learning-based statistical model. In this framework, the excitation signal obtained by an LPC inverse filter is first decomposed into harmonic and noise components using an improved time-frequency trajectory excitation (ITFTE) scheme, then they are trained and generated by a deep long short-term memory (DLSTM)-based speech synthesis system. By controlling the parametric dimension of the ITFTE vocoder, we analyze the impact of the harmonic and noise components to the perceptual quality of the synthesized speech. Both objective and subjective experimental results confirm that the maximum perceptually allowable spectral distortion for the harmonic spectrum of the generated excitation is ~0.08 dB. On the other hand, the absolute spectral distortion in the noise components is meaningless, and only the spectral envelope is relevant to the perceptual quality.
