Walkie-Talkie AI Chat is an innovative open source application that reimagines voice interaction with artificial intelligence through the familiar push-to-talk metaphor. Developed by Matthew Anorkplim Loh, Solutions Architect at Digighana, this unique AI chat interface prioritizes accessibility and deliberate communication over the rapid-fire exchanges typical of modern voice assistants.Unlike conventional voice AI implementations, this application simulates a walkie-talkie experience—users speak their message, use a customizable end word like “over,” and receive a considered response. This turn-based approach creates a more relaxed chat flow that benefits partially speech-impaired individuals while offering a refreshing alternative for any user tired of interrupting or being interrupted by their AI assistant.
Key Features of Walkie-Talkie AI Chat
🎙️ Natural Voice Interaction
Talk to the AI using your microphone with real-time voice activity detection. The application leverages the powerful Gemini Live API for low-latency, natural-sounding conversations.
🔄 Turn-Based Communication
Unique walkie-talkie mode with customizable wake/end words (default: “over”) that signals when you’ve finished speaking, creating a more orderly and accessible conversation flow.
👨🦳 Accessibility-First Design
Specifically engineered for partially speech-impaired users who need more time to articulate thoughts without pressure from real-time conversational AI systems.
💬 Chat History & Markdown
Visual chat interface with full conversation history, Markdown rendering support, and easy history management for reviewing past interactions.
🎨 Real-Time Audio Visualizer
Get immediate visual feedback for both audio input and output with a built-in audio visualizer that helps users understand when the system is listening or speaking.
🚀 Gemini Live Integration
Built on Google’s cutting-edge Gemini Live API for high-quality speech recognition and natural language understanding across 24+ languages.

From the Developer
“I designed this app to aid persons that are partially speech-impaired to interact effectively with AI via voice chat. It also works excellently for any regular voice chat user. The code can be extended as the voice chat component of a larger app with more functionality.”

What Makes This Walkie-Talkie AI Chat Unique?
While several voice AI chat applications exist, this implementation stands out through its dedicated focus on turn-based communication. Unlike 302 AI’s Voice Call or other alternatives that offer walkie-talkie as one mode among many, this project centers the entire experience around intentional, unhurried dialogue.
