Reverb ASR+Diarization, the Best Open Source ASR for Long-Form Audio
Hey everyone, My name is Lee Harris and I'm the VP of Engineering for Rev.com / Rev.ai. Today, we are launching and open sourcing our current generation ASR models named "Reverb." When OpenAI launched Whisper at Interspeech two years ago, it turned the ASR world upside down. Today, Rev is building on that foundation with Reverb, the world's #1 ASR model for long-form transcription – now open-source. I am proud to announce that we are releasing two models today, Reverb and Reverb Turbo, through our API, self-hosted, and our open source + open weights solution. ---------- We are releasing…
Reverb ASR+Diarization, the Best Open Source ASR for Long-Form Audio launched on October 3, 2024 with 12 votes, #1,072 of 5,185 launches that month and more than 75% of that year's launches.
In plain words
Reverb ASR+Diarization is an open-source speech recognition system from Rev.ai designed for transcribing long-form audio. The system offers two model variants—Reverb and Reverb Turbo—available through API, self-hosted deployment, and open-source releases. It supports speaker diarization to identify different speakers in recordings. The system is built on recent advances in automatic speech recognition technology and is available in research-oriented and developer-focused formats for different implementation needs.

I built a sub-500ms latency voice agent from scratchMar 2026 · ntik.me · ▲570I built a voice agent from scratch that averages ~400ms end-to-end latency (phone stop → first syllable). That’s with full STT → LLM → TTS in the loop, clean barge-ins, and no precomputed responses. What moved the needle: Voice is a turn-taking problem, not a transcription problem. VAD alone fails; you need semantic end-of-turn detection. The system reduces to one loop: speaking vs listening. The two transitions - cancel instantly on barge-in, respond instantly on end-of-turn - define the experience. STT → LLM → TTS must stream. Sequential pipelines are dead on arrival for natural…
Open-source, native audio turn detection model2025 · github.com · ▲126Our goal with this project is to build a completely open source, state of the art turn detection model that can be used in any voice AI application. I've been experimenting with LLM voice conversations since GPT-4 was first released. (There's a previous front page Show HN about Pipecat, the open source voice AI orchestration framework I work on. [1]) It's been almost two years, and for most of that time, I've been expecting that someone would "solve" turn detection. We all built initial, pretty good 80/20 versions of turn detection on top of VAD (voice activity detection) models. And…
Moonshine Open-Weights STT models – higher accuracy than WhisperLargev3Feb 2026 · github.com · ▲316I wanted to share our new speech to text model, and the library to use them effectively. We're a small startup (six people, sub-$100k monthly GPU budget) so I'm proud of the work the team has done to create streaming STT models with lower word-error rates than OpenAI's largest Whisper model. Admittedly Large v3 is a couple of years old, but we're near the top the HF OpenASR leaderboard, even up against Nvidia's Parakeet family. Anyway, I'd love to get feedback on the models and software, and hear about what people might build with it.
