Recall.ai - Meeting Transcription API
If you’re looking for a transcription API for meetings, consider checking out Recall.ai , an API that works with Zoom, Google Meet, Microsoft Teams, and more. Recall.ai diarizes by pulling the speaker data and separate audio streams from the meeting platforms, which means 100% accurate speaker diarization with actual speaker names.
A Powerful Open Source Video Translation / Audio Transcription / AI Dubbing / Subtitle Translation Tool
中文 | Documentation | Online Q&A
pyVideoTrans is dedicated to seamlessly converting videos from one language to another, offering a complete workflow that includes speech recognition, subtitle translation, multi-role dubbing, and audio-video synchronization. It supports both local offline deployment and a wide variety of mainstream online APIs.
- 🎥 Fully Automatic Video Translation: One-click workflow: Speech Recognition (ASR) -> Subtitle Translation -> Speech Synthesis (TTS) -> Video Synthesis.
- 🎙️ Audio Transcription / Subtitle Generation: Batch convert audio/video to SRT subtitles, supporting Speaker Diarization to distinguish between different roles.
- 🗣️ Multi-Role AI Dubbing: Assign different AI dubbing voices to different speakers.
- 🧬 Voice Cloning: Integrates models like F5-TTS, CosyVoice, GPT-SoVITS for zero-shot voice cloning.
- 🧠 Powerful Model Support:
- ASR: Faster-Whisper (Local), OpenAI Whisper, Alibaba Qwen, ByteDance Volcano, Azure, Google, etc.
- LLM Translation: DeepSeek, ChatGPT, Claude, Gemini, Ollama (Local), Alibaba Bailian, etc.
- TTS: Edge-TTS (Free), OpenAI, Azure, Minimaxi, ChatTTS, ChatterBox, etc.
- 🖥️ Interactive Editing: Supports pausing and manual proofreading at each stage (recognition, translation, dubbing) to ensure accuracy.
- 🛠️ Utility Toolkit: Includes auxiliary tools such as vocal separation, video/subtitle merging, audio-video alignment, and transcript matching.
- 💻 Command Line Interface (CLI): Supports headless operation, convenient for server deployment or batch processing.
We provide a pre-packaged .exe version for Windows 10/11 users, requiring no Python environment configuration.
- Download: Click to download the latest pre-packaged version
- Unzip: Extract the compressed file to a path (e.g.,
D:\pyVideoTrans). - Run: Double-click
sp.exeinside the folder to launch.
Note:
- Do not run directly from within the compressed archive.
- To use GPU acceleration, ensure CUDA 12.8 and cuDNN 9.11 are installed.
We recommend using uv for package management for faster speed and better environment isolation.
