Speech Re-Painting for Robust ASR

ICASSP 2025accepted

Synthetic speech is a useful source for augmentation of automatic speech recognition (ASR) systems, but there is a "sim-to-real" gap between synthetic and real speech that can limit generalization. The natural variability of real speech is essential to the training of robust ASR systems. While synth…

Extending Multilingual Speech Synthesis to 100+ Languages without Transcribed Data

ICASSP 2024accepted

Collecting high-quality studio recordings of audio is challenging, which limits the language coverage of text-to-speech (TTS) systems. This paper proposes a framework for scaling a multilingual TTS model to 100+ languages using found data without supervision. The proposed framework combines speech-t…

Parallel Tacotron: Non-Autoregressive and Controllable TTS

ICASSP 2021accepted

Although neural end-to-end text-to-speech models can synthesize highly natural speech, there is still room for improvements to its efficiency and naturalness. This paper proposes a non-autoregressive neural text-to-speech model augmented with a variational autoencoder-based residual encoder. This mo…
