Show HN: Bolna AI – Open-source voice AI agents with pluggable LLMs, TTS, ASR

Hi Hacker News! I'm Prateek - I’ve been working on Bolna, an open-source platform for building end-to-end conversational voice agents. With Bolna, developers can plug in their own LLMs, telephony systems, transcription models, and voice synthesis tools - and rapidly build apps that talk to users over phone calls or browser voice. Here’s a short demo video: https://github.com/bolna-ai/bolna/assets/1313096/2237f64f-1c... Why we built this We originally set out to build an AI interviewer for practicing coding interviews - think Leetcode with voice. But we quickly realized that the orchestration layer (LLM ↔ telephony ↔ TTS ↔ ASR ↔ prompts ↔ logic) was the real challenge. If this sounds interesting to you, please check us out! You can check us out our open source github repository at Github - https://github.com/bolna-ai or our hosted no-code/

low-code dashboard at - https://platform.bolna.ai. We’re inspired by open ecosystems like the Elastic stack and trying to follow a similar path: open by default, but easy to extend or host as needed.

Show HN: Bolna – build and ship enterprise grade voice AI in minutes

Hi Hacker News! This is Maitreya, Marmik and Prateek, co-founders of Bolna (https://github.com/bolna-ai/bolna). With Bolna, developers can create end-to-end conversational voice agents. They can connect to their own custom LLMs, their own Telephony, their own models etc. and create application features requiring voice AI. Here’s a small video: https://github.com/bolna-ai/bolna/assets/1313096/2237f64f-1c.... Our product originates from building an AI interviewer bot which can be used for practising coding interviews like Leetcode. By trying to build something like that, we realized that the orchestration layer can be a real pain point and hence something that everyone might want to use and build upon for any Voice AI feature. The hypothesis quickly got verified with the immense usage. We started off as a complete open source solution but q

uickly realized that to enable and expediate adoption and usage, we will need to create APIs on top of it so developers find it very very easy to use it. Hence, our package is wrapped over by an API layer which can be extended. Our primary focus has been to provide reliability towards latency and successful conversations. Our github repo https://github.com/bolna-ai/bolna has maintained a 30% fork:star ratio which is pretty massive from our point of view. We've seen developers fork us and try to build their own layers, their own telephony components, their own custom LLMs and models, etc. Later on we also released our hosted APIs for developers who wanted to use our managed hosted solutions - https://docs.bolna.dev/introduction and built a no-code/low-code playground for trying it out - https://playground.bolna.dev with a "chat" option to tune & test prompts since we realized that prompt is a very critical part for conversations to succeed. We recently released a complete open source end-to-end stack combining Whisper + Llama + MeloTTS (https://github.com/bolna-ai/bolna/tree/master/examples/whisp...) and hosted it's dockerized versions as well (still WIP) on docker hub. We think Bolna is quite unique since it encapsulates the underlying orchestration into API-able structure enabling developers to get started quickly via Docker, etc. I've been a great lover (and user) of the Elastic stack since 1.3x versions (circa. 2014) and trying to use a lot of inspiration from their open source process and philosophy on how to improve the adoption and usage. If this sounds interesting to you, please check us out! You can check us out our open source github repository at Github - https://github.com/bolna-ai or our hosted no-code/low-code dashboard at - https://playground.bolna.dev. We’d really love to hear your feedback and look forward to all of the comments!

Show HN: Production grade end to end open source stack for Voice AI

we have been building an open source orchestration which enables you to plug in your own TTS/ASR/LLM for end-to-end voice conversations at -> https://github.com/bolna-ai/bolna. Few days back, was having a discussion here in HN about the possibilities of having a complete open source stack for ASR+LLM+TTS. Today, we are releasing a complete open sourced Dockerized stack by merging Bolna with Whisper ASR, Llama3 and Melo TTS.

Hi Hackernews, we're Maitreya, Prateek and Marmik. Over the past few months we've been working on building a platform to build, scale and monitor voice based LLM applications. Demo (https://www.youtube.com/watch?v=OSrOmyR7oQs) 1. Open Source orchestration: We're open-sourcing our orchestration to quickly setup and create LLM based voice driven conversational applications https://github.com/bolna-ai/bolna/ 2. Hosted API Platform: Exposing our managed solution via APIs to build voice driven applications https://docs.bolna.dev/api-reference/introduction 3. Normal LLM telemetry tools won't work in giving visibility for audio bytes in and out of the system across multiple models. So, we've build our own observability layer fully integrated with the dashboard as well. 4. 3 different modes for creating agents - Lite (Intent classification based)

(useful for basic calls and really pocket friendly). Normal (<2sec latency but only one llm call means it's cheaper than nitro), Nitro (<1sec latency and but multiple llm calls means really expensive) 5. Follow up tasks like webhook integration, summarisation, and extraction. 6. Modular and extensible architecture, which means connecting two different llms yet parallel paths(for example code and english to automate leetcode screening interviews) is really easy, albeit you'll initially need some hacking until we're able to release that to both hosted and open source versions). 7. Vector and Scalar caches to reduce the entire cost (by 3x compared to deepgram + mixtral + elevenlabs) and latency by 300ms - 500ms. 8. Semantic routing Over the next weeks we'd be doing a lot of small releases here starting with a Speech language model only pipeline, integrating gazzele We'd love to welcome you guys to our community, give us feedback and together build "langchain for voice first AI assistants".
