Would you use a DIY voice assistant to interact with smart devices in your native language?
Developer ROHITCRAFTSYT has unveiled the Hermes voice assistant, an open-source project that allows low-cost ESP32 hardware to execute voice commands. The system utilizes cloud-based AI to process requests in Tamil and English, bridging the gap between basic microcontrollers and modern voice technology.
Why it matters
This architecture allows inexpensive hardware to support sophisticated voice interactions without requiring high-powered local AI processing. It provides a DIY pathway for integrating smart-home functionality at a significantly lower entry cost.
The Hermes system requires an ESP32-S3 board with a 2.4 GHz Wi-Fi connection and a Windows PC running at least Python 3.11. The build uses an INMP441 microphone and a MAX98357A amplifier to manage audio input and output for the voice assistant.
The players

This individual is the primary developer behind the open-source Hermes voice assistant project.
The details
Audio captured by the ESP32 is sent via Wi-Fi to a PC, which routes the request through Groq's Whisper model for transcription and Microsoft's neural voice service for responses. Users trigger the assistant by pressing a physical button, which initiates the processing cycle and smart-home integration commands.
Timeline
The Hermes project was officially released on October 29, 2026.
The Tech Race
This project represents a significant shift in the DIY smart-home landscape by pushing high-level voice processing to the edge using common microcontrollers. It demonstrates how developers are bypassing expensive, proprietary hardware by leveraging cloud APIs on budget-friendly components.
Users can build a custom, multi-language voice assistant for their smart homes for as little as ₹1,500. By supporting platforms like Home Assistant and MQTT, the project allows hobbyists to unify disparate devices under a single, affordable voice control interface.
The takeaway
The Hermes project demonstrates that voice-controlled automation is becoming increasingly accessible through open-source software and low-cost hardware. Hobbyists looking to automate their homes can now replicate commercial functionality at a fraction of the standard retail price.
