Validate activity before betting a new project on dc_tts. ## When NOT to use VieNeu-TTS - The application demands TTS services in languages other than Vietnamese. - You seek a solution that performs inference exclusively on GPUs as VieNeu-TTS prioritizes CPU usage even with GPU availability. - Deployment needs are not compatible with on-device processing, and cloud-based TTS solutions are preferred. ## Common questions ### What is the difference between dc_tts and VieNeu-TTS? dc_tts: A TensorFlow Implementation of DC-TTS. VieNeu-TTS: Vietnamese TTS with instant voice cloning, on-device and real-time CPU inference. See the comparison table for live GitHub stats and shared categories. ### When should I choose dc_tts over VieNeu-TTS?
