What people say

The meeting is still there afterward

I followed a two-hour English seminar with source and translation side by side — I missed far less.
When a question came up, I picked a suggested reply and spoke it with TTS. The meeting did not stall.
Searching the seminar record meant I did not have to write the notes myself.

Smooth real-time interpretation,Butterbun

From the next meeting, the notes are kept

Seminars, conferences, and work meetings. Listen, translate, and search later.
