The short answer
The two leading open-source talking-avatar tools in 2026 are SadTalker (13,994 stars, CVPR 2023) - the classic that turns one photo + audio into a talking head - and LivePortrait (18,845 stars, Kuaishou) - the newer, faster model with better head motion control. Both run locally and free.
SadTalker - the classic
- Input: one portrait image + one audio file (or text via TTS).
- Output: a video of the photo speaking with lip sync and head motion.
- Well-documented; runs via CLI, Gradio web UI, or ComfyUI.
git clone https://github.com/OpenTalker/SadTalker
cd SadTalker
pip install -r requirements.txt
python inference.py --driven_audio input.wav --source_image photo.jpg --result_dir output/
- Works best with clear, front-facing portraits.
- 512x512 output; a GPU makes generation fast (30-60s per clip).
LivePortrait - the modern option
- Kuaishou's model; much better head pose and expression transfer.
- Also animates multiple faces, supports driving video (not just audio).
- Faster and higher quality than SadTalker on most inputs.
git clone https://github.com/KwaiVGI/LivePortrait
cd LivePortrait
pip install -r requirements.txt
python inference.py --src_img photo.jpg --driving_audio audio.wav
Which to use
| Need | Tool |

Practical tips

- Pair with a TTS tool (Kokoro, see our voice over guide) for fully automated video.
- For long videos, generate in segments and stitch - both tools are designed for short clips.
