01What a Hermes Agent Phone Call Is and How It Works
A Hermes agent phone call lets you ring up your AI assistant like it's a real person. When you call, the agent talks back to you using a natural voice and can perform tasks on your local setup while you're away from your computer. This works by connecting 11Labs voice service with your Hermes agent through Twilio, which gives you a phone number to dial.
When you call, the system routes your voice through 11Labs, which turns it into text for Hermes. Hermes then uses its tools, memory, and skills to complete your request and sends a reply back through 11Labs as speech. The whole loop happens in real time, so you can ask for file edits, schedule events, or recall past sessions just by talking.
02Key Features of the Phone-Based Hermes Agent
A Hermes agent phone call brings several useful features to your AI assistant. First, you can operate your agent from any location using just your phone, even while at the gym or traveling. The system uses 11Labs for voice, which means the replies sound human and come back quickly.
You can also create a pro version of your own voice with 11Labs, making the agent sound like you.
- You can call from anywhere — gym, car, or out walking — and still control your local AI setup.
- The voice uses 11Labs, which offers fast, realistic replies and lets you clone your own voice for a personal assistant feel.
- All conversations are saved in recent sessions, so you can review what you asked and what the agent did.
- The agent can write and edit files, schedule cron jobs, retrieve memory, and run terminal skills, all over the phone call.
- You can switch between different AI models, but Claude 3.5 Haiku gave the fastest response time in tests.
03How to Set Up the Hermes Agent Phone Call System
Setting up a Hermes agent phone call is simple if you follow the 11Labs integration guide. You need two main pieces: an 11Labs API key and a Twilio phone number. Once you have those, you can let your AI agent handle the setup itself.
- Get an 11Labs API key from the 11Labs website.
- Create a Twilio account and buy a phone number that you can call.
- Open the 11Labs guide for Hermes integration and give the instructions to your Hermes agent.
- Tell your Hermes agent to set up the integration using your API key and Twilio number.
- Approve the permissions that the agent asks for during setup.
- Test the system by calling your Twilio number and speaking to your Hermes agent.
04Using Hermes Agent Over the Phone: Real Examples
In the episode, Julian Goldie demonstrated several tasks using a Hermes agent phone call. He asked the agent to write a poem and save it to his Downloads folder. The agent created a file called moments whisper.txt and even read the poem back to him.
When he asked for an extra paragraph, the agent read the file, used a patch tool to add the new stanza, and offered to show the updated version.
Next, he asked the agent to schedule a daily Japanese learning session at 3 PM. The agent used the cron job tool to set it up, corrected a format error, and confirmed the schedule. He then asked the agent to recall yesterday's work using session search.
When the agent found no interactions, it offered to check the previous day or a specific topic. Finally, he asked for a joke, and the agent told a science pun. All of this happened in a single phone call with voice replies.
05Speed and Model Comparisons During Testing
Julian Goldie tested different AI models with the Hermes agent phone call setup. Claude 3.5 Haiku gave the fastest response times when combined with Hermes and 11Labs. Other models like Qwen and Step 3.7 Flash were not fast enough for controlling the agent smoothly.
The voice reply speed also depends on the model you choose.
He also noticed that simpler tasks — like writing a text file or scheduling a job — got quick replies. More complex tasks, such as building a website, caused longer delays. For the best experience, use a lightweight model and keep requests straightforward.
The phone call itself felt faster than using the voice button inside the agent operating system, likely because of the direct integration.
06Tips, Limits and Mistakes to Avoid
When using a Hermes agent phone call, stick to simple tasks for the best experience. Avoid asking for big coding projects like building a whole website — those will take too long and may time out. Choose a fast model like Claude 3.5 Haiku to keep replies snappy.
Slower models like Qwen or Step 3.7 Flash can make the agent feel unresponsive.
You can customize the voice with 11Labs — Julian used an English butler style, but you can clone your own voice for a more natural feel. Be aware that conversation transcripts are saved in recent sessions, so you can review what was done. Finally, make sure you have both an 11Labs API key and a Twilio phone number before starting the setup, or the integration will fail.
07Who Should Use the Hermes Agent Phone Call Feature
A Hermes agent phone call is for anyone who wants to control their AI assistant while away from their computer. If you often work remotely, go to the gym, or travel, you can still manage your local setup through a simple phone call. Developers and power users who already rely on Hermes for automation will find this feature especially useful — it lets them stay productive without being tied to a desk.
The integration also works inside the agent operating system as a voice mode called Hermes Jarvis, where you can click a button and speak directly. But the phone call option adds mobility. Whether you are a freelancer, a business owner, or someone automating personal tasks, this setup turns your AI agent into a true voice assistant that you can reach anytime.
08Why Voice Control Matters for AI Agents
Adding voice to a Hermes agent phone call changes how you interact with AI. Instead of typing commands or using a chat interface, you simply speak and hear replies. This feels more natural and saves time, especially when you are doing other activities.
Julian Goldie pointed out that this is different from other agents, which only let you type or send voice input without a live spoken reply.
The ability to call your agent from anywhere also removes the need to carry a laptop. You can ask it to write files, check your schedule, or recall memories while you are walking. This makes the agent feel like a real assistant that you can reach whenever you need it.
The combination of Hermes, 11Labs, and Twilio delivers a practical, futuristic way to work with AI hands-free.
