Hi HN! Last year the project I launched here got a lot of good feedback on creating speech to speech AI on the ESP32. Recently I revamped the whole stack, iterated on that feedback and made our project fully open-source—all of the client, hardware, firmware code. This Github repo turns an ESP32-S3 into a realtime AI speech companion using the OpenAI Realtime API, Arduino WebSockets, Deno Edge Functions, and a full-stack web interface. You can talk to your own custom AI character, and it responds instantly. I couldn't find a resource that helped set up a reliable, secure websocket (WSS) AI…

Sayline▲83I built a voice dictation app for macOS mostly because I was tired of how awful Siri is and I didn't want to pay a subscription for cloud tools. The app uses NVIDIA's Parakeet v3 (TDT) as the primary engine. Inference is handled by the FluidAudio library. It's insanely fast on M-series chips. For Intel users, I added local Whisper support ranging from Tiny up to Large v3 Turbo (quantized to save space). The interesting part was the AI integration. I originally tried to pipeline the ASR output into Apple's Intelligence Foundation Model. It was a nightmare, because the content moderation…

Tikpal▲24We’re building Tikpal, an AI voice productivity tool based on a simple principle: Human creativity should remain the core engine. AI should be an accelerator, not the protagonist. The goal is to reduce screen dependency and cognitive fragmentation, and let people work in a more natural “voice-first” flow. Instead of clicking through interfaces and context-switching between apps, you talk to Tikpal, and it helps you think, structure ideas, and execute tasks. Three layers we are focusing on: FOCUS — Tools like Pomodoro, breathing cues, ambient audio, and micro-interactions to create sustained…
