Shortlist Clevercast when adding live multilingual closed captions and subtitles to conferences and webinars matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Run both through a week of actual calls to see which suits your workflow.

Clevercast is a SaaS platform for multilingual live streaming and accessibility, aimed at organizations broadcasting events, conferences, webinars, and meetings to global audiences. Incoming audio and video are sent from an encoder to Clevercast, which generates AI closed captions described as having high accuracy, including for streams where multiple languages are spoken. From that speech-to-text source it can produce live subtitles in multiple languages, synthetic AI voice translations that viewers select per language, and on-site scrolling transcripts displayed on screens for event attendees. A web interface lets operators correct the AI transcription in real time, improving the resulting captions and translations, and remote human interpreters can also be added for events with strict quality requirements. Streams are delivered via HLS through a global CDN and can be embedded in Clevercast's player or distributed to platforms such as YouTube. It suits enterprises, international bodies, educational institutions, and media companies that need accessible, language-inclusive live broadcasts rather than a personal meeting note-taker.

WhisperLiveKit is an open-source, self-hosted toolkit for ultra-low-latency real-time speech-to-text and speaker diarization. Rather than naively running Whisper on each audio chunk, it uses state-of-the-art simultaneous-speech research for intelligent buffering and incremental processing, which preserves transcription quality while streaming results with minimal latency. The project ships a complete backend built on FastAPI with WebSocket support, an OpenAI-compatible REST API, a Deepgram-compatible WebSocket protocol, and a simple, customizable HTML and JavaScript web interface that captures microphone audio and streams it to the server. It supports multiple ASR backends including Whisper variants, Voxtral, and Qwen3-ASR, covers 200+ languages with translation, and includes real-time speaker diarization and voice activity detection to reduce processing overhead. It can handle multiple concurrent users on a single backend and is distributed via PyPI with Docker images for both GPU and CPU. Licensed under Apache 2.0 and actively maintained into 2026, the project explicitly lists meeting transcription, accessibility tooling, and podcast or call transcription with speaker identification among its intended use cases, making it a practical building block for private, on-premise meeting transcription pipelines. Pricing varies by plan. Check the official website for current pricing.
