DeepL Voice is currently stopping short of delivering the result as an audio or video file itself: the service is aimed at real-time, live conversations and video conferencing, and comes through as text, not audio.

In the first of these, you can set up your translations to appear as ‘mirrors’ on a smartphone — the idea being that you put the phone between you on a meeting table for each side to see the words translated — or as a transcription that you share side by side with someone. The videoconferencing service sees the translations appearing as subtitles.
