What Is an AI Audio Translator?
An AI audio translator converts spoken audio into written text in another language. TurboCast first transcribes the recording with Gemini-class speech recognition, then translates the transcript into any of 17 languages while keeping timestamps and speaker labels intact.
The numbers that matter: 17 target languages, 100+ recognized source languages, 3 free translations a day of up to 30 minutes each, and files up to 210 minutes on the Pro plan. Everything runs in the browser, with nothing to install.
One honest clarification. This audio translator turns speech into translated text, not into a dubbed voice. If you need the translation read aloud, send it to our text to speech tool afterwards and pick a voice in the target language.
How to Translate Audio in 3 Steps
No software, no separate transcription step, no copying text between tools. Upload once and the audio translator does the rest. One tip: if the recording has unusual names or technical terms, fix them in the original transcript first, because the translation is generated from that text.
Step 1 — Upload your audio or video
Drag a file into the tool above or click to browse. MP3, WAV, M4A, FLAC and OGG audio all work, and so do MP4 and MOV video files. Free accounts get 100MB and 30 minutes per file.
Step 2 — Pick the target language
Choose English, Spanish, French, German or any of the other 17 languages. You never select the source language: the audio translator detects it automatically across 100+ languages.
Step 3 — Read, compare and export
The transcript opens with the translation ready. Toggle between original and translated text, fix anything you like, then export as TXT, SRT, VTT, PDF or DOCX.
Translate Audio Into 17 Languages
English, Spanish, French, German, Portuguese, Italian, Dutch, Polish, Turkish, Russian, Arabic, Chinese, Japanese, Korean, Indonesian, Vietnamese and Thai. Pick any of them as the target, and let the recording be in whatever language it happens to be. We list what the audio translator supports today rather than a rounded-up number.
100+ source languages, detected automatically
Speech recognition covers more than a hundred languages and major regional accents. You do not tell the tool what language the speaker uses; it works that out from the first seconds of audio.
17 target languages you can actually read
Every target language is one the translation model handles well for long-form spoken text, not just short phrases. That is why the list is 17 and not 150.
Any direction, one recording
Translate a Spanish interview into English, then translate the same recording into German for a colleague. Each translation is cached, so switching back is instant.
Popular Audio Translation Pairs
The four directions people use the audio translator for most. The workflow is identical for every pair; only the target language changes.
Spanish audio to English
Interviews, podcasts and lecture recordings from Spain and Latin America. Regional accents are handled by the recognition step, and the English translation keeps speaker labels so you can follow who said what.
French audio to English
Translate audio French to English for coursework, conference talks or client calls. Timestamps survive the translation, so you can jump back to the French original at any line.
English audio to Spanish
Turn an English webinar or training recording into a Spanish transcript your team can read. Export it as SRT and you have translated captions ready for the video.
Chinese audio to English
Mandarin lectures, meetings and voice notes come out as English text with paragraph breaks and chapters, which is far easier to skim than listening twice.
More Than a Translated Transcript
Most online audio translator tools hand you a block of translated text and stop there. TurboCast keeps the structure of the original recording so the translation is something you can actually work with.
Original and translation side by side
Switch between the source transcript and the translated version with one click. Spot-check a sentence against the original whenever a phrase looks odd.
Timestamps and speaker labels survive translation
Every paragraph in the translation is anchored to the same moment in the audio as the original. Speaker 1 and Speaker 2 stay labeled, and you can rename them.
Export in five formats
TXT and DOCX for reading and editing, PDF for sharing, SRT and VTT when you need translated subtitle files. For burning captions into a video, use the AI subtitle generator.
How Accurate Is AI Audio Translation?
Translation quality is capped by transcription quality. A clear, single-speaker recording produces a translation you can publish after a light read-through. Noisy group audio needs more editing. We would rather tell you that than quote a percentage measured on studio recordings.
What affects accuracy
Three things: audio quality, accents, and specialist vocabulary. Product names and rare surnames are the most common misses. Fix them in the original transcript and re-run the translation.
How long it takes
Transcribing a one-hour recording takes a few minutes. Translating the finished transcript takes seconds, and every language you pick is cached for the next visit.
Private by default
Uploads are deleted 24 hours after processing. Transcripts and translations belong to your account and are never used to train models.
Turn the Translation Into Notes, Flashcards or a Podcast
This is where TurboCast stops being just an audio translator. The same transcript that was translated already carries a summary, chapters and key points, and it can feed every other tool on the site.
Summary and chapters in the target language
Skim a foreign-language lecture in two minutes. The AI summary and chapter list are generated alongside the transcript, so you get the shape of the recording before reading the full translation.
Study it with Smart Notes
Turn the translation into structured notes, then into flashcards and a quiz. Language learners use this to drill vocabulary straight from real conversations.
Listen to it as an AI podcast or voice-over
Hand the translated content to the AI podcast generator for a narrated explainer, or paste it into text to speech for a verbatim read in a native voice.
Who Uses an Audio Translator
Four workflows we see every week. If yours is different, the tool does not care what the recording is about.
Language learners and students abroad
Translate a lecture or a podcast episode, read it next to the original, and turn the tricky passages into flashcards. Far more useful than a dictionary.
Researchers and journalists
Foreign-language interviews become searchable English text with timestamps. Quote accurately, and jump back to the exact second when a claim needs checking.
Distributed teams
A meeting recorded in one language becomes readable minutes in another. Share the DOCX, or the summary alone, with colleagues who were not on the call.
Creators reaching a second audience
Translate your own episode and export SRT captions in a second language. The audio translator gives you the text; your video editor does the rest.
