About the project

Mother Earth AI is a climate communication project that gives planet Earth a literal voice. People pick up a phone (or visit the website) and ask "Mother Earth" questions about the climate, the ecosystem and the conditions that sustain human life. The AI answers in the planet's voice.

The project was developed in a Creative Lab on climate communication at the Federal Centre of Excellence for the Cultural and Creative Industries (Kompetenzzentrum für Kultur- und Kreativwirtschaft des Bundes) and won the K3-Preis 2023 für Klimakommunikation.

N3XTCODER collaborated with the Mother Earth team on the self-hosted voice agent architecture, connecting their LLM backend to their public website and their physical "Mutter Erde Telefon" installations.

The challenge

Mother Earth's brief had a constraint that ruled out most off-the-shelf voice AI providers from day one: the project could not promote carbon emissions through hyperscaled AI infrastructure. A voice agent that gives Earth a voice cannot run on the same hyperscaler stacks driving up data centre energy consumption. Sovereignty, autonomy and carbon-independence from big AI providers were non-negotiable.

The team had also developed a strong creative concept: an LLM fine-tuned on a special dataset including the Universal Declaration of the Rights of Mother Earth and traditional sayings from indigenous communities, giving the AI a distinct personality and perspective. That fine-tuning had to live on their own infrastructure, end to end.

The solution

A fully self-hosted voice agent built on open-source components:

• LLM platform: Ollama, running on the team's own infrastructure
• Interface: Open WebUI
• Voice pipeline: speech-to-text and text-to-speech components running locally
• Workflow orchestration: n8n

Crucially, the voice agent now connects to two surfaces:

1. Online, via the project's public website at mother-earth.ai
2. In-person, via the "Mutter Erde Telefon" – a physical phone installation built on a Raspberry Pi with a Wi-Fi connection. People at museums, exhibitions and climate events can pick up the receiver and have a spoken conversation with "Mother Earth" without an app or screen.

The Telefon plugs into the same self-hosted infrastructure as the web version, so the same fine-tuned model and the same data flows serve both surfaces.

The outcome

• A fully interactive voice agent grounded in a curated knowledge base about Earth, climate and the conditions for life
• Used online and in physical exhibition / museum spaces
• K3-Preis 2023 für Klimakommunikation winner
• Carbon-independent from hyperscaled AI providers, on a renewable-energy hosting model
• Plug-and-play physical installation: Raspberry Pi + Wi-Fi means the Telefon can travel to any climate event or exhibition with minimal setup
• Concrete demonstration that self-hosted, sovereign voice AI is viable today for public-interest projects

Why this matters

Most "voice AI" coverage focuses on commercial assistants from a handful of US providers. Mother Earth AI shows that the same conversational quality is achievable on a fully open, fully self-hosted, fully sovereign stack – and that the resulting system can travel from a server room into a museum exhibition without any compromise on the underlying architecture. For public-interest projects with sensitive constraints around data, energy or sovereignty, this is the proof-of-concept that the alternative path works.
