HeyGen alternatives for avatar videos and dubbing

FaceFusion suits replacing HeyGen lip sync on footage you supply. Its installable app combines speech synchronization with face editing and enhancement, letting you process the face and frames in one workflow. It does not generate a complete script-based presentation.

pyVideoTrans covers HeyGen video translation and dubbing. Transcribe, translate and proofread speech, assign voices to speakers and generate aligned dubbed audio. You can choose local recognition, translation and speech models or connected cloud APIs.

SmartSub covers translating and dubbing existing videos through editable, timed subtitles. Generated voices follow those timings, and the app exports the captions with a mixed dubbing track. It does not create avatars or adjust mouth movements.

MuseTalk suits the talking-avatar part of HeyGen with your own portrait or footage and audio. A local browser preview lets you adjust the face region before generating speech-aligned mouth movements; narration and presentation editing need separate tools.

VideoLingo suits producing bilingual subtitles and optional dubbed versions of HeyGen source footage. Its workflow combines local recognition, timed captions and translation review; translation and dubbing depend on the configured providers.

YouDub-webui dubs existing videos with cloned voices while retaining background music and sound effects. Its most established workflow is English-to-Chinese video, with Chinese-to-English also supported; it does not supply stock presenters.

Voice-Pro covers the recording and dubbing side of HeyGen-style work. Prepare audio, transcribe or translate speech, and generate a replacement voice from reference recordings; it requires internet access and focuses on audio rather than avatar lip sync.

LatentSync suits replacing HeyGen lip-sync adjustment on existing filmed faces. Supply the video and new audio through its browser interface, then generate matching mouth movements; it does not supply stock avatars or compose slides.

SoniTranslate covers translating an existing video and generating dubbed speech that follows its original timing. It is a video-localization workflow; you supply the recorded video rather than build a presenter from stock avatars.

LivePortrait covers a narrower HeyGen avatar-animation job: transfer expressions and head movements from a recorded performance to a portrait. Reuse motion templates and adjust eye or lip openness; speech-driven dubbing needs another tool.
