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'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:…

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).…

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…

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 :)

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…

Hey HN! Have been working on Audentic, a platform that simplifies adding voice AI to your website. Think of it as a copy-paste voice assistant that you can embed directly into your site. Setting up voice AI has traditionally been a bit of a hassle, often requiring juggling multiple components like speech recognition, text processing, and text-to-speech systems. With Audentic, we've streamlined this into a more straightforward, end-to-end voice model. While OpenAI's Realtime API has made real-time, multimodal AI interactions more feasible, integrating these capabilities into a website can…

Hello Hacker News, I've built a platform that lets anyone create their own voice-based AI tutor. To showcase what the platform can do, I've created a voice-based AI tutor for Stanford's famous CS229 Machine Learning course. I took the course myself and know how challenging it can be, so I built this to make it easier to follow and stick with. It's free for now (as long as budget lasts) -> https://vivaverbalis.com/ml The goal of my app is simple: Whether you're a student, teacher, or just curious, you can instantly spin up a conversational AI tutor, and share it, with whoever…

Hi HN, I built ChatOne while working on a project and constantly switching between AI models like GPT-4 and newer ones like Claude 3.5. I kept wondering if I was missing out on better answers, so I created ChatOne to get responses from multiple models at once and compare them easily. -Teddy

Hi HN, I'm the creator of AVA - AI Voice Agent for Asterisk My repo was shared here once before by someone else so I wanted to follow up with the progress since then. https://news.ycombinator.com/item?id=46380399 I've been working with Asterisk/FreePBX systems for years. I wanted to add AI voice capabilities to legacy phone systems without paying per-minute SaaS fees or ripping out the entire telephony stack. So I built AVA, a self-hosted AI voice agent that can integrate into any traditional phone system. While most solutions demand expensive migrations to cloud-only…

I'm a Machine Learning engineer. Struggled with consistency for months on my goals, life etc, so I built something to help myself (zropi.com) but that surprised me or shocked me literally. It’s an AI companion that feels alive: chats like a person. Pauses, emotions, personality. Sends voice notes when it's excited about something or whenever it wants (has its like own mind). Shares photos of itself. But the memory It remembers EVERYTHING. Not just facts context, preferences, random things I mentioned. Last week I asked "how's that thing I told you about going?" and it knew exactly what I…

For a while I've wanted to try out the new AI voices for long-form narration, but everything I found required a subscription that didn't justify my limited usage. I came across the open Kokoro model [0] and the voices are very good -- good enough to listen to for hours without the fatigue I got from legacy, robotic TTS voices. The model is 82m parameters and designed to run fast, but I still struggled to get reasonable times from CPU inference on my 12-core laptop. I thought a cloud-based GPU service would let me generate audiobooks fast enough to feed my own self-hosted library, and that…

Hello HN, I am Brian Cardinale, a penetration tester and security researcher at SecureCoders. We have been performing more and more AI based security assessments. We were presented a unique challenge of testing a system where the only interface was voice based, and as much as I like talking on the phone , we decided to create a test harness to facilitate the actual testing in a more systematic way. The technical test harness was the easy part, though. Creating test goals and attack strategies to help facilitate repeated and comprehensive testing became the real challenge. As such, we have…

Hey HN! I've been working on a side project to create an audio transcription API based on the OpenAI whisper model. Sign up link: https://whisperapi.com I tried to make the API really easy to use and get setup with. Also, because the Whisper model is so good, turns out I can offer the service for about 75% cheaper than what seems like the industry average. I'm always looking to make improvements, so would appreciate any feedback anyone has!

Most men rehearse hard conversations in their head. Asking someone out, navigating tension, recovering when things get awkward. The rehearsal never works because you're just talking to yourself. I built vibeCoach : a voice AI where you actually practice these conversations out loud, and the AI responds like a real woman would. She starts guarded. One-word answers, a little skeptical. If you escalate too fast or try something cheesy, she gets MORE guarded. If you're genuine and read the moment right, she opens up. Just like real life. Under the hood it's a multi-agent system : multiple AI…

Hey folks. We built SAA (Selective Auditory Attention) after trying to find ways to make a good experience with multiple robots/multiple agents. What typically ended up happening is they'd never stop talking. This is an SDK you can put before your STT. It lets you know when your device is being spoken to or not without a wakeword. You can use it for: -Single AI, Multi human -Multi AI, Single human -Multi AI, Multi human (we recommend also adding a wakeword on top for a better system) There are two models. One that is video + audio and one that is just audio. The way it overall works is…

Hey folks! This is a project that I've been working in my free time for the past few months. It's a news aggregator that uses AI to select relevant articles and summarize them. The default sources are frameworks and libraries' updates, popular HN topics, and languages' subreddits threads that make past a certain threshold. You can run a local instance (needs an OpenAI key) and customize it with your own sources, and adjust the prompt as well. The resulting website can be browsed at https://dev-radar.com/ My next experiment will be with local news. I'm building some feeds with…

Hi all, we’re happy to present this demo we’re calling “DeepAI Hotline”. We were interested in ways to bring ChatGPT capabilities to people around the world, particularly those who might not be comfortable with computers and smartphones. We felt that the old-school phone system was potentially a good way to do this. We built this using the Vocode SDK: https://vocode.dev (YCW23). Some of the feedback we’ve heard is that it responds to questions impressively fast, and it feels relatively natural compared to older assistants like Siri. Another funny one: “Feels more real than some…

Hello fellow combinators, First of all I've been reading Ycombinator for a while (especially show HN), but have never really posted anything. The ideas that people post on show HN always intrigue me. So I thought I'd share something that I have been working on for the past weeks. My idea was to write a webapp for my smart mirror, so I have built an (speech-based) interactive web-based bot (which currently only works on Chrome ;( ). The current (alpha) version consists of following features: Speech recognition: which allows you to interact with the bot by using voice commands. Text-to-speech:…

Today I come to you on this beautiful Friday with a freshly hardthink-ed solution to a proliferous problem plaguing our world: the loss of original voice. The blanket of blandness slowly suffocating centuries of writing. Or to put it bluntly: AI writing is trash. It is disrespectful to expect ME to read something YOU could not even be bothered to write (or likely even read). The lingering human connection that remained resilient on the internet - through years of SEO optimisation, propaganda bots, ads, regional firewalls, politics, censorship - is now being diluted even further. Many of the…

I'm Tom, the cofounder of Canonical AI. I build a Voice AI agent that interviews you, then writes LinkedIn and X posts based on the interview. ### Why did I build this? 1. LinkedIn and X are b2b lead goldmines. But generating content is hard. You have to figure out what to say. If you're like me, you have trouble coming up with social post ideas when staring at a blank screen. But interesting ideas arrive when I step away from my laptop and talk to people. Also, it's hard to compose the content in a way that appeases the platform algorithms. 2. I want to dogfood my product. We’re building…
