24 alternatives to Voicebun

Hey HN, I built Voicebun as a pet project because I was frustrated with how locked-down and rigid voice agents still are—many tools are either closed platforms, lack deep customization, or charge a lot just to test ideas. I wanted a way to quickly spin up AI voice agents that I could fully control—from the voice itself to the logic behind every word. Voicebun is an open-source voice agent builder. You can: - Clone voices and generate audio using your own scripts and prompts - Dynamically change prompts based on user input - Add custom logic through functions and webhooks (e.g. hit an API,…

    Made using Google’s Lyria music model — an image → music translator. I’m a designer at Google, doing a self-initiated 30 days with Gemini experiment. This is technically a promo, but honestly just pleased with how this one turned out. I don’t write code — this was entirely vibecoded.

    Hi HN - we’ve been working on a new UX for building realtime voice agents with minimal code. We’ve built a ton of voice agents in the past few years. We noticed that voice agent dev follows a pretty typical pattern: ⁃ Start with a “single prompt” version that dumps all relevant context and instructions into a one prompt, and provide access to all necessary tools the agent will ever need ⁃ As the agent gets more complex and users discover more edge cases, break the single-prompt version out into a more complex structure that gives a user more control over the precise conversational flow.…

    TLDR: We created a personalised Andrej Karpathy tutor that can response to questions about his Youtube videos in sub 1 second responses (voice-to-voice). We do this using a voice enabled RAG agent. See later in the post for demo link, Github Repo and blog write up. A few weeks ago we released the worlds fastest voice bot, achieving 500ms voice-to-voice response times, including a 200ms delay waiting for a user to stop speaking. After reaching the front page of HN, we thought about how we could take this a step further based on feedback we were getting from the community. Many companies were…

    Hi HN, We’ve built Echovox Studio—a browser-based, end-to-end audio content workflow that takes you from idea → research → script → voice → edit in a few minutes. Why we made it While prototyping an audio-streaming product, we talked to creators (founders, educators, bloggers, podcasters). The same pain points kept surfacing: no time to research or script + trouble finding relevant ideas + a fragmented toolchain (recording, TTS, editing all separate) What it does (not limited to below): 1) 1-click topic summaries or deep content research and writing (LLM) 2) Voice generation your cloned…

    I’ve been working on an SDK for creating voice AI apps. If you’ve ever wanted to make consumer voice apps, this is for you. There are some neat ideas in here that I’m really proud of: the decorators make everything very readable, and the prompting system is wonderfully dynamic. The basic setup command is: npx create-pocket-app This will create a Next.js app that’s ready to deploy. Check out the live examples on the home page to get a feel for what’s possible, and to see the code!
