EasySub translates spoken audio by creating an editable source transcript first, then generating a target-language text or subtitle track. Upload an audio or video file, or paste any YouTube/video URL, choose the language actually spoken, enable Add translation, and review both tracks before downloading TXT, SRT, VTT or ASS.
How to translate audio to text online
- Add the recording. Open the EasySub subtitle workspace, upload an audio or video file from your device, or paste any YouTube/video URL.
- Choose the language actually spoken. Do not select the desired output language as the source. Correct source-language selection makes the first transcript easier to review.
- Enable translation before generation. Turn on Add translation, choose the target language and start processing. EasySub creates a source transcript with timing, then a separate translated track.
- Correct the source first. Listen again for names, numbers, negatives, speaker changes and domain terms. A source error will otherwise be carried into the translation.
- Review and download the translation. Check meaning, tone, regional wording, line length and timing. Export TXT for readable text or SRT, VTT or ASS for a synchronized subtitle track.
Audio translator, audio to text and dubbing are different
Audio to text
The recording is transcribed into the same language. Use this when you need meeting notes, an interview transcript, podcast text or same-language captions without translation.
Audio translation
The source speech is transcribed, reviewed and then translated into another language as text or timed subtitles. Source and translation remain separate tracks.
Dubbed audio
A new voice track speaks the translated text. This page does not promise a translated MP3 or automatic dubbing export; text-to-speech and voice replacement are separate production steps.
Why audio translation starts with a transcript
Directly translating an uncertain audio draft hides where a mistake began. A transcript-first workflow leaves an auditable source: you can listen to the recording, correct the source wording and then compare the translated line with the reviewed meaning.
This matters for interviews, lessons, podcasts, voice notes and technical recordings. A small error in a name, decimal, date or negative can make a fluent translation factually wrong. Correcting the source first prevents the same error from spreading into every target language.
Can I translate a voice recording or audio message?
Yes. Upload a voice recording or an audio/video file that you are authorized to process. For an audio message saved on your device, use the clearest original file available instead of a heavily compressed forwarded copy. Select the actual spoken language, add the translation target and review short or unclear phrases while listening.
If several people speak, check speaker changes manually. Background music, phone compression, overlapping voices, code-switching and distant microphones can reduce recognition quality even when the language itself is supported.
Is this a live audio translator?
This page describes a file and URL workflow, not a live microphone interpreter or real-time call translator. You add an existing recording or any YouTube/video URL, wait for processing, review the transcript and translation, and then download the result. Searches for “live audio translator” or “live captions” therefore should not be interpreted as a promise of real-time conversation translation.
Translate audio in 150+ languages
EasySub supports transcription and translation workflows across more than 150 languages. To translate English audio into Spanish, for example, choose English as the source and Spanish as the target. To translate Spanish speech into English, reverse those choices. The source language must always describe the recording, not the language you want to receive.
Coverage does not mean identical accuracy for every accent, dialect, recording condition or subject. Prepare a short list of names, places, brands and specialist terms, then compare them with the audio before approving the target-language track.
Translate audio from YouTube and video URLs
Paste any YouTube or video URL into the input field, choose the spoken language and enable translation before generation. EasySub creates the timed source transcript and translated subtitle track inside the project, so you can review both versions with the media.
EasySub does not automatically publish the translation back to YouTube or another platform. Download the reviewed subtitle file or export a captioned video, then upload it through your normal publishing workflow.
Which translated audio output should you download?
| Output | What it contains | Use it when |
|---|---|---|
| TXT | Readable source or translated text without subtitle timestamps. | You need a transcript, notes or text for editing rather than a synchronized caption track. |
| SRT | Numbered subtitle cues with start and end timestamps in a widely supported text format. | You need translated captions for YouTube, an editor, a course platform or a compatible player. |
| VTT | Timed WebVTT caption text for web playback. | Your website or online player specifically requests VTT. |
| ASS | Timed subtitles with additional styling information. | Your player or editing workflow supports ASS styling. |
| Captioned video | A rendered video with the selected translated captions visible on screen. | You want viewers to see the translation without loading a separate subtitle file. |
When both language tracks are available, choose Source only, Translated only or Bilingual according to the destination. Bilingual captions need extra checking because two languages can cover more of the picture and increase reading load.
Audio translation quality checklist
| Check | What to review | Why it matters |
|---|---|---|
| Source transcript | Names, numbers, dates, negatives, quotations, speaker changes and technical terms match the recording. | A translation cannot repair a source phrase that was transcribed incorrectly. |
| Meaning and tone | The target text preserves the speaker’s intention, level of formality and emotional tone without adding explanations. | A fluent sentence can still distort the original claim or relationship. |
| Terminology | Brands, product names, abbreviations and domain vocabulary follow an approved spelling or glossary. | Consistency matters across long recordings and multiple language versions. |
| Timing and readability | Translated lines begin and end with the speech, use natural breaks and fit the available reading time. | Target-language wording may be longer than the source even when the meaning is correct. |
| Final destination | The chosen language, characters, file format and playback have been tested in the real player or editor. | A correct project can still fail after export because of encoding, font or platform requirements. |
Can EasySub translate songs and podcasts?
You can process a podcast, interview, lesson, voice note or song recording that you own or are authorized to use. Spoken podcasts with clear microphones are usually easier to transcribe than sung lyrics because music, elongated syllables, harmonies and creative pronunciation can obscure word boundaries.
For songs, compare every line with an authorized lyric source when one is available, and treat rhyme or singable adaptation as a separate editorial task. A literal subtitle translation and a new lyric adaptation do not serve the same purpose.
Is the online audio translator free?
You can open the sample subtitle editor to inspect the workflow before creating a project. Available processing time, models and export options depend on the current account balance and plan; “start for free” does not mean unlimited audio transcription or translation. Check the current pricing page before processing long recordings.
EasySub is a self-service AI-assisted tool, not a human audio translation agency. For legal, medical, financial, safety-critical or publication-sensitive recordings, arrange qualified review appropriate to the subject and target audience.
