Customer Reviews

SyncWords - Review - icon

Many thanks... for thinking outside of the box to solve my closed captioning need... to provide closed captioning for 47 breakout sessions, two keynotes and a CIO Panel. SyncWords partnered with us, worked to understand the conference platform technology, and provided their innovative solution for automatic captioning.

We have used them for both of our 2021 virtual conference events. Easy to communicate with, quick response time, and accurate live translations every time :) Fully integrated into our streaming platform. Best part as a non profit association, they are very economical.
