Hi, we're using the latest interactive avatar API (Audio-to-Video) as we want to use a more powerful LLM. We're using OpenAI realtime for A2A realtime audio, via LiveKit. We have this in Production and it works really well except for one thing; latency. We're seeing up to 5 seconds of latency on avatar turns and this just doesn't work for us. Is there any way we can remove this issue? We're not voice cloning etc. We want to scale up usage of photorealistic avatars but can't until this problem has been solved. Thanks. Eamus

Last night I signed up for the Scale API plan, but when I use the API, it tells me that I have the trial version. How do I fix this, please?

I HAVE A CREATOR PLANE AND A FREE API . I CAN NOT HAVE HIGH RESOLUTION WITH API ONLY 720X1280 . HOW CAN I GET HIGH RESOLUTION WITH API ? .

Hello HeyGen Team,
I am integrating the HeyGen Streaming API (WebRTC) to use Interactive Avatars in real time (lip-sync, camera eye contact, sub-second latency) inside my platform (Mocha / custom web app).
However, despite having:
Active HeyGen subscription
Streaming API access
API Key generated
Interactive Avatar enabled
I am experiencing the following issues:
Real-time response not working correctly
Lip-sync not synchronized
Streaming session not initializing properly
Latency higher than expected / sometimes no stream at all
Integration details:
Method: Streaming API (WebRTC)
Mode: Interactive Avatar (Full mode)
Frontend: Web (Mocha)
Backend: Node.js
Session created via HeyGen Streaming endpoints
API Key: correctly generated and passed in headers
Could you please help verify:
If my API key is properly enabled for Streaming API
If my account is fully activated for Interactive Avatar streaming
If there is any missing permission or quota on my account
If LiveKit / WebRTC session creation flow is correct for production use
This project is a real commercial platform (Venturis 13 LifeOS), and I have invested significantly in HeyGen services, so I need to make sure the Streaming Avatar works in real time as advertised.
Thank you for your technical assistance.
Best regards,
