Real-time live subtitling and speech translation for web conferences and streaming video usually rely on cloud services like Google Cloud Speech or Azure Cognitive Services. For privacy-sensitive environments, running this pipeline entirely on local hardware is essential.
By pairing Whisper.cpp (or faster-whisper) for sub-second audio transcription with Ollama (Llama 3.2 / Qwen 2.5) for contextual streaming translation, developers can achieve real-time bilingual subtitle overlays with zero cloud dependencies.
