Callhackernews.com – The missing voice interface for Hacker News
Hey there HN! I believe the future of AI communication will be more voice and less text. Low-latency realistic voice interactions are finally becoming feasible. I've built a few voice-first apps on Retell AI using Elevenlabs voices. This one uses Claude Haiku for responses and Mixtral to switch between posts and comments. The AI knows about the top 30 posts and their comments on Hacker News right now. After a Google sign-in you can try it free for 10 minutes. I'd love to hear your thoughts!

all alternatives →- ASAlexa skill for Hacker News that summarizes articles2018 · ▲111
I've made a Hacker News skill for Alexa so people can get tech news while driving, cooking, or cleaning. The first version lists post titles and summarizes articles: https://www.amazon.com/dp/B07CKVDXC3 I'll have lots of time over the next few months to refine it and add things like - comment summaries - selecting posts by topic, and eventually - answering questions about articles What do you think of the skill? What I should add to it? What do people think about voice assistants in general? To keep in touch, talk to me on Twitter or by email:…

- WOWe open sourced Vapi – UI includedMar 2026 · github.com · ▲8
We kept hitting the same wall building voice AI systems. Pipecat and LiveKit are great projects, genuinely. But getting it to production took us weeks of plumbing - wiring things together, handling barge-ins, setting up telephony, Knowledge base, tool calls, handling barge in etc. And every time we needed to tweak agent behavior, you were back in the code and redeploying. We just wanted to change a prompt and test it in 30 seconds. Thats why Vapi retell etc exist. So we wrote the entire code and open sourced it as a Visual drag-and-drop for voice agents ( same as vapi or n8n for voice).…
- WTWelcome to "Voice AI Stack" Weekly – A Home for Voice AI Builders2025 · videosdkweekly.substack.com · ▲6
Hey HN, This newsletter didn’t come from a growth hack or content strategy. It started with frustration. Every week, I was drowning in blogs, PR blasts, and Twitter threads trying to keep up with Voice + AI. New models dropping. Partnerships overnight. Startups in India and Asia pushing infra upgrades that no one was covering. But whenever I wanted to know what really mattered, the signal was buried under the noise. And there wasn’t a single newsletter focused on India’s Voice AI ecosystem — most only covered the US. So I built the thing I wished existed: Voice AI Stack — a newsletter on…
- IBI build a dedicated news site for AI developers (think HN for AI/ML)2023 · news.aiapipro.com · ▲8
Think of HackerNews, but only for AI content. Did build this out of the wish for easier discoverability of new technologies in the AI/ML space. Obviously, so far only a tiny small community, but maybe a few of you find it nice to be around and want to post a link there every now and then :)
- IMI made a language tool that forces you to talk2025 · hanasu.ai · ▲5
Hey HN! I created Hanasu.ai after my 9-5 job as a side project. Previously I'd used Duolingo to learn Japanese, but failed spectacularly when I actually spoke with my roommate from Tokyo. Now, after OpenAI improved their Realtime audio model in December and reduced pricing, I spent my entire winter break building. So how does it work? Just choose a daily topic and converse with the AI model: (1) Didn't catch a phrase? Double tap to reveal a transcript. (2) Couldn't understand? Double tap for translations powered by Google. (3) Can't recall that intricate Chinese/Japanese character? Just…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
