Zirui Li, Jens Edlund, Yicheng Gu, Nhan Phan

ICASSP 2026poster

Text-to-speech (TTS) development is limited by scarcity of high-quality, publicly available speech data for most languages outside a few high-resource languages. We present Nord-Parl-TTS, an open TTS dataset for Finnish and Swedish based on speech found in the wild. Using recordings of Nordic parlia…

Multi-Scale Sub-Band Constant-Q Transform Discriminator for High-Fidelity Vocoder

Yicheng Gu, Xueyao Zhang, Liumeng Xue, Zhizheng Wu

ICASSP 2024accepted

Generative Adversarial Network (GAN) based vocoders are superior in inference speed and synthesis quality when reconstructing an audible waveform from an acoustic representation. This study focuses on improving the discriminator to promote GAN-based vocoders. Most existing time-frequency-representat…
