Incremental Disentanglement for Environment-Aware Zero-Shot Text-to-Speech Synthesis
Ye-Xin Lu, Hui-Peng Du, Zheng-Yan Sheng +2
This paper proposes an Incremental Disentanglement-based Environment-Aware zero-shot text-to-speech (TTS) method, dubbed IDEA-TTS, that can synthesize speech for unseen speakers wh…
A Neural Denoising Vocoder for Clean Waveform Generation from Noisy Mel-Spectrogram based on Amplitude and Phase Predictions
Hui-Peng Du, Ye-Xin Lu, Yang Ai +1
This paper proposes a novel neural denoising vocoder that can generate clean speech waveforms from noisy mel-spectrograms. The proposed neural denoising vocoder consists of two com…
APCodec+: A Spectrum-Coding-Based High-Fidelity and High-Compression-Rate Neural Audio Codec with Staged Training Paradigm
Hui-Peng Du, Yang Ai, Rui-Chen Zheng +1
This paper proposes a novel neural audio codec, named APCodec+, which is an improved version of APCodec. The APCodec+ takes the audio amplitude and phase spectra as the coding obje…
ERVQ: Enhanced Residual Vector Quantization with Intra-and-Inter-Codebook Optimization for Neural Audio Codecs
Rui-Chen Zheng, Hui-Peng Du, Xiao-Hang Jiang +2
Current neural audio codecs typically use residual vector quantization (RVQ) to discretize speech signals. However, they often experience codebook collapse, which reduces the effec…
BiVocoder: A Bidirectional Neural Vocoder Integrating Feature Extraction and Waveform Generation
Hui-Peng Du, Ye-Xin Lu, Yang Ai +1
This paper proposes a novel bidirectional neural vocoder, named BiVocoder, capable both of feature extraction and reverse waveform generation within the short-time Fourier transfor…
Towards High-Quality and Efficient Speech Bandwidth Extension with Parallel Amplitude and Phase Prediction
Ye-Xin Lu, Yang Ai, Hui-Peng Du +1
Speech bandwidth extension (BWE) refers to widening the frequency bandwidth range of speech signals, enhancing the speech quality towards brighter and fuller. This paper proposes a…
