About

What it is: Reachy Mini ElevenLabs Conversation is an app that connects a Reachy Mini robot to an ElevenLabs Conversational AI agent. The robot hears you through its microphone and answers through its speaker. Its head moves and its mouth animates while it speaks, and the agent's replies can trigger matching expressions. The Space itself is a static project page.

Who it suits: Owners of a Reachy Mini robot who want it to talk with people in a natural voice.

Industry | Who uses it | How they use it | Example
Education | Teachers and students | Learn by talking with a robot that answers questions | A robot helping with a classroom topic
Reception | Front desk teams | Let the robot greet visitors and give information | A robot answering common visitor questions
Accessibility | People with mobility challenges | Control the robot and ask it things by voice | Asking the robot a question without a keyboard

If you do not own a Reachy Mini robot, you can skip it, because the app runs through the robot's own control software.

Where to use it:

• The Reachy Mini Control application, in its Apps section
• A web browser, to read the project page at Hugging Face

Use case | Who | What they get back
Personal assistant | Robot owners | A robot that answers questions and helps with reminders
Learning companion | Students | A robot that explains things in conversation
Storytelling and games | Families | A talking robot for stories, jokes and simple games

How to set it up: You need a Reachy Mini with its Control application and an ElevenLabs account. Public agents work without an API key, while private agents need one.

• A Reachy Mini robot and its Control application
• An ElevenLabs account with a Conversational AI agent
• The agent's Agent ID, which starts with agent_
• An API key, only if your agent is private

1. Sign up at ElevenLabs and create a Conversational AI agent.
2. Copy the agent's Agent ID.
3. In the Reachy Mini Control application, open Apps, find ElevenLabs Conversation and click Install.
4. Start the app and open its settings page, which the app serves on port 7861 of the same computer.
5. Enter your Agent ID, and your API key if the agent is private.
6. Adjust the emotion detection settings if you want, then click Save Settings.

Emotion detection can also be set in a .env file with these lines.

ENABLE_EMOTION_DETECTION=true
EMOTION_CONFIDENCE_THRESHOLD=0.3
EMOTION_COOLDOWN_SECONDS=3.0

How to use it: Once the settings are saved, the app connects to your agent by itself. It listens through the robot's microphone, replies through the speaker and animates the head. You just talk to the robot.

Tool | What it does
Agent ID | Sets the personality, voice and abilities of your robot
API key | Is needed only for a private agent
ENABLE_EMOTION_DETECTION | Switches emotion detection on or off
EMOTION_CONFIDENCE_THRESHOLD | Sets how sensitive detection is, from 0.0 to 1.0
EMOTION_COOLDOWN_SECONDS | Sets the time between emotion actions

Example: You install the app, paste your Agent ID into the settings page and click Save Settings. You then say hello to the robot. It answers in the voice of your agent, turns to face you on a greeting and moves its head while it talks.

For newcomers and experts: An ElevenLabs agent is a voice assistant you set up online, and the Agent ID is how the robot finds it. To start, create an agent, copy its ID and install the app from the Apps list.

Microphone audio arrives at 44.1 kHz stereo and is resampled to 16 kHz mono. The agent's audio comes back at 16 kHz and plays through the robot's speaker as 16-bit PCM. Lip sync runs in real time. Emotion detection reads the agent's reply text, and a confidence threshold and a cooldown limit how often it moves the robot.

Robot microphone picks up your voice
Audio is resampled and sent to the agent
Agent replies with speech
Robot plays it and animates its head

Good to know:

• Limits: it needs a Reachy Mini robot, and emotion detection only reacts to happy, sad, thinking and greeting replies
• License: Apache 2.0
• Cost to run: an ElevenLabs account and agent are needed, and the source names no price
• Data it reaches: your speech goes through the robot's microphone to your ElevenLabs agent, and your Agent ID and any API key sit in the app's settings
• Not for: use without a Reachy Mini, since the app is built for that robot
