Vocnu for podcasts
Upload an episode to Vocnu and get it back in another language: a voice reads the translation over your lowered original sound, or alone, with subtitle and transcript files for show notes. An hour-long episode costs €3.96 to €6.00 in Standard quality. One voice reads every speaker, so it suits a solo show better than an interview, and our test below shows why.
Uploads run in the web app in your browser, with nothing to install.
What we tested
On 10 November 2026 we cut 59.5 seconds of English dialogue between a man and a woman from Tears of Steel, the Blender Foundation's open film, saved it as an MP3 and asked Vocnu for a Spanish voice-over as audio, in Premium.
- It cost 2 credits: under a minute is billed as one, at 2 credits a minute in Premium.
- Back came an MP3 of 59.533 seconds, exactly as long as the upload, at 48 kHz stereo and 192 kb/s.
- With it, the Spanish subtitles as SRT, VTT and ASS files, and the English transcript as an SRT file.
- One male voice read every line, hers too. We measured the pitch: her line is around 296 Hz in the original, and every line of the Spanish file sits between 107 and 123 Hz.
An earlier cut of exactly 60 seconds came out of our MP3 encoder at 60.029 seconds and was quoted 4 credits, two started minutes. A clip close to a whole minute is worth trimming a little.
Files in, files out
- In: MP3, M4A, WAV, AAC, OGG, Opus, FLAC and other common audio and video formats, up to 10 GB and 5 hours.
- Out: the voice-over as M4A, MP3, WAV, FLAC or OGG, as long as the episode.
- Your original sound stays under the voice, lowered while it speaks, so listeners still hear the music and the hosts' laughter. Or turn it off, and the file holds the voice and silence between its lines.
- The subtitles in the new language as SRT, VTT and ASS files, and a transcript of the original, for show notes or a video version of the episode.
- One job makes one language. For the next, start a new job from the same upload within 7 days, without uploading it again.

The prices run from the largest credit pack to the smallest, and the credits never expire. You see the quote before the job starts and are never charged more; failed or cancelled jobs are refunded in full.
When Vocnu is not the right pick
- Your show is an interview or a panel, and listeners must tell the voices apart. Vocnu reads every speaker in one voice, as our test showed; ElevenLabs keeps each speaker's voice.
- You want the episode in your own voice. Vocnu reads with its own voices; ElevenLabs and Rask AI can clone yours.
- You record live and want it translated as you speak. Vocnu translates a finished file.
- You want to check and correct the translation line by line before it is voiced. Vocnu has no editor for that.
