FAQs

What are the main differences between VieNeu-TTS Turbo and Standard modes?

VieNeu-TTS Turbo mode is optimized for extreme speed and real-time CPU inference, making it suitable for edge devices and low-end hardware, though with slightly lower audio quality for very short phrases. The Standard mode (VieNeu-TTS v1/v2) offers maximum audio quality and high-fidelity voice cloning, typically requiring GPU acceleration.

Can VieNeu-TTS clone voices with minimal audio input?

Yes, VieNeu-TTS supports instant voice cloning with just 3-5 seconds of reference audio. This feature is available in both the Turbo v2 and GPU-accelerated Standard modes, allowing users to synthesize new speech in a cloned voice.

Does VieNeu-TTS support both English and Vietnamese languages?

Yes, VieNeu-TTS offers bilingual support for both English and Vietnamese. It provides smooth and natural transitions between the two languages, powered by sea-g2p for text normalization and phonemization.
