Frequently asked questions

Is WaveSpeedAI a good Synthesia alternative?

Yes, if you want presenter videos without a subscription. Turn any portrait and a voice-over into a lip-synced presenter with InfiniteTalk, Seedance 2.5 or LongCat Avatar, create narration with ElevenLabs, Gemini, MiniMax or Qwen3 TTS, dub videos into other languages, and pay per run.

How do I turn a script into a presenter video?

Create the voice-over from your script in the audio generator, then open the avatar generator, upload a portrait and that audio file, and hit generate.

Can I make the same video in other languages?

Yes. Generate the narration in another language with a multilingual voice model and lip-sync your presenter to it, or dub a finished video with ElevenLabs Dubbing, which keeps the original speaker's voice.

Do I need a subscription?

Never. Add credits when you want and spend them on any model. No monthly fees, no seats, nothing to cancel.

Can I try it for free?

Yes. Eligible new accounts get $1 in free credits, and you can sign up without a credit card. Some premium models may not be available with trial credits.

Is there an API?
