WhisperLive and whisper-ctranslate2
These two tools are **ecosystem siblings**, as Softcatala/whisper-ctranslate2 provides a command-line client for Whisper, a system that Collabora/WhisperLive implements with near-real-time capabilities.
About WhisperLive
collabora/WhisperLive
A nearly-live implementation of OpenAI's Whisper.
Supports multiple inference backends (Faster-Whisper, TensorRT-LLM, and OpenVINO) for optimized performance across different hardware, with pluggable model sizes and a client-server architecture for concurrent transcription. Features Voice Activity Detection, real-time translation between any languages, and OpenAI-compatible REST API endpoints alongside native WebSocket streaming for low-latency audio input from microphones or files.
About whisper-ctranslate2
Softcatala/whisper-ctranslate2
Whisper command line client compatible with original OpenAI client based on CTranslate2.
Leverages CTranslate2's optimized inference engine with support for quantization (int8, float16) and batched processing to achieve 4-16x speedup over OpenAI's implementation while maintaining accuracy. Adds speaker diarization via pyannote.audio, Voice Activity Detection filtering, live microphone transcription, and custom fine-tuned model loading—all while maintaining CLI compatibility with the original Whisper client. Ships with Docker images pre-loaded with models and supports diverse hardware backends (Intel MKL, Apple Accelerate, NVIDIA GPUs, ARM64).
