    Hey HN, this is Igor, one of the engineers behind Inworld Runtime, which we're releasing today in public preview. We built it to solve the common problem we and our customers had: engineers spend more time on AI ops and plumbing than on actual feature development. This was often due to the challenge of using Python for I/O-bound, high-concurrency workloads and complexity maintaining pipelines with streams that use always-changing ML models. Our solution is a high-performance runtime written in C++ with the core idea of defining AI logic as graphs. For instance, a basic voice-to-voice…

    Welcome to Project S.A.T.U.R.D.A.Y. This is a project that allows anyone to easily build their own self-hosted J.A.R.V.I.S-like voice assistant. In my mind vocal computing is the future of human-computer interaction and by open sourcing this code I hope to expedite us on that path. I have had a blast working on this so far and I'm excited to continue to build with it. It uses whisper.cpp [1], Coqui TTS [2] and OpenAI [3] to do speech-to-text, text-to-text and text-to-speech inference all 100% locally (except for text-to-text). In the future I plan to swap out OpenAI for llama.cpp [4]. It is…

    Hi HN, I built a fun little side project that recreates the classic Microsoft SAM voice from Windows XP—entirely in the browser. SAM TTS uses phoneme-based synthesis (no AI models), written in JavaScript with Web Audio API. You can type any text, adjust pitch/speed/mouth/throat settings, and instantly hear the robotic voice we all remember from early 2000s computers. You can even download the generated audio as a WAV file, which makes it handy for game developers, meme creators, retro enthusiasts, or anyone who wants to bring a touch of digital nostalgia to their work. This…
