In this paper, we propose a neural vocoder-based textto-speech (TTS) system that effectively utilizes a source-filter modeling framework. Although neural vocoder algorithms such as SampleRNN and WaveNet are well-known to generate high quality speech, its generation speed is too slow to be used for real-world applications. By first decomposing speech signal into spectral and excitation components using the sourcefilter framework, we train the two components separately, i.e. training the spectrum or acoustic parameters with a long short-term memory model and the excitation component with a SampleRNN-based generative model. Unlike the conventional generative model that needs to represent the complicated probabilistic distribution of speech waveform, the proposed approach needs to generate only the glottal movement of human production mechanism. Therefore, it is possible to obtain high quality speech signals using a small-size of the pitch interval-oriented SampleRNN network. The objective and subjective test results confirm the superiority of the proposed system over a glottal modeling-based parametric and original SampleRNN-based speech synthesis systems.
