Promptvc: Flexible Stylistic Voice Conversion in Latent Space Driven by Natural Language Prompts

ICASSP 2024accepted

Stylistic voice conversion aims to transform the style of source speech to a desired style according to real-world application demands. However, the current style voice conversion approach relies on pre-defined labels or reference speech to control the conversion process, which leads to limitations…

DSPGAN: A Gan-Based Universal Vocoder for High-Fidelity TTS by Time-Frequency Domain Supervision from DSP

ICASSP 2023accepted

Recent development of neural vocoders based on the generative adversarial neural network (GAN) has shown obvious advantages of generating raw waveform conditioned on mel-spectrogram with fast inference speed and lightweight networks. Whereas, it is still challenging to train a universal neural vocod…

Distinguishable Speaker Anonymization Based on Formant and Fundamental Frequency Scaling

ICASSP 2023accepted

Speech data on the Internet are proliferating exponentially because of the emergence of social media, and the sharing of such personal data raises obvious security and privacy concerns. One solution to mitigate these concerns involves concealing speaker identities before sharing speech data, also re…

Multi-Speaker Expressive Speech Synthesis via Multiple Factors Decoupling

ICASSP 2023accepted

This paper aims to synthesize the target speaker’s speech with desired speaking style and emotion by transferring the style and emotion from reference speech recorded by other speakers. We address this challenging problem with a two-stage framework composed of a text-to-style-and-emotion (Text2SE) m…

Preserving Background Sound in Noise-Robust Voice Conversion Via Multi-Task Learning

ICASSP 2023accepted

Background sound is an informative form of art that is helpful in providing a more immersive experience in real-application voice conversion (VC) scenarios. However, prior research about VC, mainly focusing on clean voices, pay rare attention to VC with background sound. The critical problem for pre…

UniSyn: An End-to-End Unified Model for Text-to-Speech and Singing Voice Synthesis

AAAI 2023technical

Text-to-speech (TTS) and singing voice synthesis (SVS) aim at generating high-quality speaking and singing voice according to textual input and music scores, respectively. Unifying TTS and SVS into a single system is crucial to the applications requiring both of them. Existing methods usually suffer…
