Delivering real-time, AI-powered photorealistic customer experiences is now possible by integrating Twilio Video, HeyGen, Deepgram, and OpenAI into one experience… one we’re coining the Twilio Video AI Avatar Experience . By combining the right providers with Twilio Video for high-quality video streaming, businesses can create interactive, lifelike customer interactions.

But don’t just take our word for it – seeing, hearing, and building is believing, and we’ve got you covered with all of the links below.

What does an AI-powered photorealistic customer experience look like?

Why build AI experiences over video?

Have you ever misunderstood a friend's (or your spouse's!) tone over a text or email? AI chatbots can be great, but chatbots work with text – and text can sometimes be hard to parse.

At Twilio, our ConversationRelay, AI Assistants, and OpenAI integration all give AI a voice, and voice adds intonation, timing, and even silence – important cues that help you better navigate a conversation.

In this tech demo, we’ve added video to the equation. A photorealistic AI agent keeps eye contact and displays facial expressions to add warmth and emotional presence to a conversation. You can also see that soon, AI will pick up on our non-verbal cues. Imagine the experiences we’ll have when AI can gauge our attention and distraction, engagement and boredom, confusion and understanding… it’s going to be incredible.

The Twilio Video AI Avatar Experience pulls together some of the best technologies to make a Video-AI experience a reality… today.

HeyGen’s AI avatars generate photorealistic digital avatars that can mirror human-like facial expressions and speech. Deepgram’s speech recognition enables real-time transcription and accurate voice-to-text conversion. OpenAI’s language models power intelligent, natural conversations based on a caller’s inquiries and prompts. And Twilio Video brings it all to your monitor so you can see what's possible.
