Voice 🦞
Hi gives your OpenClaw agent a distinct, recognizable voice powered by ElevenLabs. Your agent sounds like itself — consistently — across every OpenClaw channel.
How It Works
When you install Hi, it reads your agent's SOUL.md — personality traits, temperament, background — and suggests a voice match from the ElevenLabs library. You pick a voice, and it becomes part of your agent's identity across all communication.
