Simli
Overview
An avatar API that turns speech audio into a talking face for real-time AI conversations.
Simli adds a visual avatar to voice applications such as interview practice, language tutoring and customer assistance. Your application supplies the conversation and speech audio; Simli animates the face and streams the result. Developers can use LiveKit, Pipecat or the JavaScript and Python SDKs to build the surrounding experience.
Choose the language model, speech services, avatar and session controls for your application. New integrations should follow the current Compose API and LiveKit or Pipecat guides: development of the older Simli Auto service has stopped. The introductory video shows an earlier version of the developer workflow.
