VieNeu-TTS

Overview

VieNeu-TTS is an advanced on-device Vietnamese Text-to-Speech (TTS) model with instant voice cloning.

Trained on ~1000 hours of high-quality Vietnamese speech, this model represents a significant upgrade from VieNeu-TTS-140h with the following improvements:

Enhanced pronunciation: More accurate and stable Vietnamese pronunciation
Code-switching support: Seamless transitions between Vietnamese and English
Better voice cloning: Higher fidelity and speaker consistency
Real-time synthesis: 24 kHz waveform generation on CPU or GPU

VieNeu-TTS-1000h delivers production-ready speech synthesis fully offline.
