SpeakFlow Pro listens to any call, meeting or video and reads it to you in your language — and turns what you say into theirs, spoken through a virtual microphone or typed into the chat.
macOS 14.4+ on Apple Silicon & Intel, notarized by Apple · Windows 10/11 on x64 & ARM · No API keys
One app, four situations — pick a preset and press Play.
Meet, Zoom, Teams, Zalo, FaceTime. Hear them in your language; they hear you in theirs through the SpeakFlow virtual microphone.
Any audio on your computer — YouTube, podcasts, lectures, films — spoken in your language with captions, keeping pace.
One microphone, two people, two languages: the app detects who is speaking and translates both ways out of the speakers.
Speak, and the translation is typed into WhatsApp, Slack, Telegram or any chat box — checked by a language model first.
Nearly 100 multilingual voices. Record 30 seconds and the app speaks every language in your own voice.
Tell it the subject, or let it detect the meeting context — names, jargon and product terms come out right.
A floating caption panel you can put anywhere, a full bilingual transcript and an AI summary on demand.
Push-to-talk, replay the last sentence, type-to-speak, select any text and hear it translated (⌘⇧D).
Hours are counted only while a session runs. They never expire. The first hour is on us.
SwiftUI on the Mac, a native build on Windows. The screens below are the Mac version.

Yes — SpeakFlow for iPhone & Android: live subtitles over any app, face-to-face conversations and recorded meetings turned into minutes.
No. This page is about SpeakFlow Pro, the Mac and Windows app for live speech. The Chrome extension, SpeakFlow Translate, translates YouTube videos in the browser and is a separate, free product.
No. Everything is included in the hours — recognition, translation and voices. Just download, take your free hour, and press Play.
Only while a session is running (from Play to Stop), in real time, whatever preset you use. Stop the session and the meter stops. Hours never expire.
Mac: macOS 14.4 (Sonoma) or later, on Apple Silicon and Intel. Windows: Windows 10 or 11, on x64 and ARM. The same licence key works on either, and your hours are shared between them.
For calls, headphones are best. For in-person use the app has an echo guard, so the built-in speakers work.
Audio is streamed to the speech engine for translation and not stored; transcripts and settings stay on your own computer. We don't sell your data.
If something isn't working, email support@speakflowlive.com — we'll help or refund unused hours.
