Building a Real-Time AI Avatar for Coaching and Training Simulations
cerebrium.ai/blog/how-to-build-a-real-time-ai-avatar-for-training-and-coaching At Cerebrium, we have recently built a few demos showing voice AI capabilities (worlds fastest voice agent & realtime RAG agent) but we wanted to push the boundary and see if we could create realistic, human-like situations to train and onboard teams to perform better - recreating real life scenarios! An example of this is a sales coach for your sales team, an investor pitch or even prep for a notoriously stressful YC interview . To achieve this there were a few difficult problems to solve, namely: - How…

What it does
Simulate real-life scenarios at scale using an AI Avatar and see performance increases
Generative AI unlocks many use cases for us to respond to questions and situations dynamically very intelligently but there are many scenarios where a text based solution is not suitable. What if we could could create realistic, human-like situations in order to train and onboard teams to perform better - recreating real life scenerios? In this demo, you can chose whether you would like to be interviewed or taught to be better at sales all achieved through Carter - our AIfrom coaching.cerebrium.ai

A personalised AI tutor with < 1s voice responses2024 · educationbot.cerebrium.ai · ▲72TLDR: We created a personalised Andrej Karpathy tutor that can response to questions about his Youtube videos in sub 1 second responses (voice-to-voice). We do this using a voice enabled RAG agent. See later in the post for demo link, Github Repo and blog write up. A few weeks ago we released the worlds fastest voice bot, achieving 500ms voice-to-voice response times, including a 200ms delay waiting for a user to stop speaking. After reaching the front page of HN, we thought about how we could take this a step further based on feedback we were getting from the community. Many companies were…

Hey HN, we're the co-founders of LemonSlice (try our HN playground here: https://lemonslice.com/hn). We train interactive avatar video models. Our API lets you upload a photo and immediately jump into a FaceTime-style call with that character. Here's a demo: https://www.loom.com/share/941577113141418e80d2834c83a5a0a9 Chatbots are everywhere and voice AI has taken off, but we believe video avatars will be the most common form factor for conversational AI. Most people would rather watch something than read it. The problem is that generating video in real-time…
