Show HN: Voice skill for AI agents – sub-200ms latency via native SIP (github.com)

A new voice skill for OpenClaw agents has been introduced that leverages OpenAI's Realtime API to facilitate real-time voice conversations with sub-200ms latency. This solution integrates easily with Twilio's SIP, allowing users to interact via phone—a significant advancement as most current voice AI solutions rely on multiple services, leading to higher latencies. The setup requires a basic configuration with Python and Node.js, and includes features like session continuity, where conversations can persist across voice and text channels, enhancing the user experience. This development is significant for the AI/ML community as it demonstrates the capability to streamline voice interactions with AI agents, making conversations feel more natural. Key technical details include the use of the OpenAI Realtime API for instant communication and the seamless invocation of OpenClaw's tools during calls through the `ask_openclaw` function, allowing the AI to respond to user queries in real-time. The initiative not only optimizes voice interactions but also opens pathways for further innovations in voice AI, such as call recording and multi-account support, positioning OpenClaw as a competitive player in the market.
