Add a Pipecat-powered Agent Voice Bot community example

Description

EDIT: I realized the link to the repo is somewhat buried in the PR itself. Here's the actual code: https://github.com/chadbailey59/agent-voice-bot

Introducing Agent Voice Bot (I couldn't think of a better name): A Pipecat voice frontend for OpenClaw, Hermes, and LangChain Deep Agents Code. It puts a fast "voice loop" in front of the slower-but-smarter "agent loop" of Hermes, OpenClaw, or Deep Agents Code. It supports using those runtimes directly, but more importantly, it natively supports using NemoClaw-managed sandboxes and all of the great stuff you get from NemoClaw. (Think "voice approval of sandbox-gated actions", for example.)

It's a similar approach to VoiceClaw with a "voice loop" and "agent loop". But instead of a voice-to-voice model, Agent Voice Bot uses the new multi-agent framework introduced in Pipecat 1.3 for the voice loop. This means you get full Pipecat-style control of how the voice loop behaves, like configuring interruptions, etc. Heck, if you want, you can replace the current cascading voice pipeline with all sorts of realtime models.

Through the power of having Codex/Claude Code write a lot of code for me, Agent Voice Bot does its best to support each backend as much as possible. For example, you can use your voice to send steering messages to an OpenClaw backend. There's much more info on this in the repo README.

The example remains in its standalone repository so its implementation, dependencies, compatibility testing, and support lifecycle stay with its maintainer.

Verification

• python scripts/check_license_headers.py --check
• git diff --check
• Relevant example setup or syntax checks

The standalone repository test suite passes with 46 tests, and its Python source distribution and wheel build successfully.

Release And Compliance

• No secrets, local .env files, private certificates, snapshots, or token caches are included.
• No third-party dependencies are added to this repository.
• Public documentation is free of internal-only links or private workspace details.
• Commits include DCO sign-off (git commit -s).

Thank you for your contribution. We are looking for code contributions in a similar format to the personal community sentiment agent. You are welcome to link to the NemoClaw Community repository on your documentation as you wish, but we are not able to accept documentation updates to external repositories at this point.
