FAQ

Yes. Lipsync models are trained on phonemes (sounds), not specific languages. Whether the audio is in English, Japanese, Hindi, or a made-up fantasy language, the AI syncs the mouth movement to the sound waves accurately.

Absolutely. You can upload any audio file (WAV/MP3), whether it's a real human recording or AI-generated text-to-speech from tools like ElevenLabs or OpenAI.

If you use an Image-to-Video model like SadTalker, the AI will generate natural head movement and eye blinking. If you use a Video-to-Video model like VideoReTalking, it usually preserves the original head motion and only modifies the lips.

WaveSpeed optimizes these models for speed. Offline generation (high quality) typically processes at 0.5x real-time (e.g., a 10s video takes 5s to generate). Real-time models (MuseTalk) can process faster than real-time for live interaction.

Most base models output at 512x512 or 720p specifically for the face region. However, WaveSpeed includes a "Face Enhancer" (GFPGAN) step in the pipeline to upscale the face and composite it back into 1080p or 4K videos.
