SpeakFlow gives you two tools: a native Mac app for real-time conversation translation, and a Chrome extension that translates & dubs YouTube videos.
Pick the one you need — or use both.
Real-time voice translation for calls, meetings and videos. Hear any conversation in your language and speak back through a virtual mic.
Translate & AI-dub any YouTube video right in your browser — natural voice-over, subtitles, SRT export and AI summary.
Translation streams as people speak — no waiting.
Lifelike neural voices, never robotic.
From English & Spanish to Japanese and Arabic.
