No.
In the case of sacrament or other meetings with less than 500 connections, you can use zoom webinar. That supports setting up a translator and members can select that the speaker or the translator.
For larger events, like stake conference, you'd use zoom to produce the meeting. You'd use a RTMP feed from zoom to the church webcast for English, and you'd give the Spanish speakers a link to the Webinar. (Assuming that wouldn't go over the 500 stream limit.)
Either way, you're not using the Teradek.
