Welcome to "Voice AI Stack" Weekly – A Home for Voice AI Builders
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…
What it does
In the maker’s words, at launch
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 India, Asia, and global Voice AI updates. What you’ll get every Friday Product launches that actually move the Voice + AI ecosystem forward Infra upgrades & strategic deals (with context on why they matter) Advances in speech tech, translation & agent performance A spotlight on VideoSDK’s AI Agent features — what’s shipping, and what’s next If you’re a developer, PM, researcher, or just curious about the future of AI voices & agents in India and beyond — this is for you. Behind the Scenes Last night at 11:30 pm, we were testing our VideoSDK AI agent. Everything was running perfectly—smooth, steady, no problems at all. Then suddenly, every agent started speaking in opera voices. Instead of answering questions, they were singing like they were on stage in Italy. We couldn’t stop laughing. Then came the panic. And finally, the fix. That’s what building in this space is really like—messy, surprising, and full of moments you don’t expect. Behind every polished demo, there are nights like this: bugs, laughter, and small wins that make the journey worth it. This newsletter is my way of opening that door for you. A peek into the experiments, the stumbles, the “wait, did that agent just…” moments that make this space exciting. Subscribe here to stay in the loop. https://videosdkweekly.substack.com/p/welcome-to-voice-ai-st... And if you’ve got a friend building or curious about Voice AI — forward this to them. Let’s cut through the noise, together. See you tomorrow Sagar Kava

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:…

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!

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…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
