How to Dub a Podcast with AI — Audio Dubbing Guide

Why dub a podcast instead of just translating the transcript?

Text translation is great for subtitles or show notes. But listeners want to listen. AI dubbing takes the translated text and synthesizes spoken audio in the target language, giving your audience a native listening experience without you recording anything new.

Step 1 — Export your podcast episode

Export your episode as an MP3 or WAV file from your DAW or podcast hosting platform. Most platforms offer a direct download. Keep the file under 100 MB for best results, which covers most episodes up to roughly 2 hours at standard bitrates.

Step 2 — Upload and configure

Upload the file to AI Audio Translator. Set the source language to the spoken language of your episode. Choose your target language — for example, Spanish if you want a Spanish-language version. Enable the Generate dubbed audio toggle before submitting.

Step 3 — Let the AI handle transcription and dubbing

The system first transcribes the episode to text, then translates it, then synthesizes the translated script into speech. This three-stage process means the dubbed version is semantically accurate rather than a word-for-word literal read.

Step 4 — Download the dubbed audio

Once ready, play back the dubbed audio directly in the browser to review it. Download the file and upload it to your podcast host as a separate language feed, or embed it alongside your original episode.

Publishing tips

Create a separate RSS feed per language for proper podcast platform indexing.
Use the translated transcript as your show notes for the dubbed episode.
Include "[Spanish]" or similar in the episode title so listeners know the language.
Check the dubbed audio at a few points for pacing — AI voices may speak slightly faster or slower than your original.

Which podcasts benefit most?

Interview shows with a clear single speaker per segment
Educational or tutorial-format podcasts
Business and industry news shows
Language-learning or storytelling podcasts

Highly conversational shows with overlapping speakers or heavy slang may need more review after AI dubbing. For those formats, translation-only (without dubbing) may be the better starting point.
