Clear answer
What does an audio translator do?
An audio translator turns spoken language in a recording into a listenable track in another language. UnmarkAI first creates a source transcript, translates the spoken meaning, and then generates the target-language voice. It is different from an audio-to-text tool because the final deliverable can be heard, not only read. The transcript is kept in the workflow so an editor can check names, product terms, numbers, or unclear moments before voice generation. That checkpoint is useful for authorized interviews, lessons, podcasts, research recordings, and narration where a small source error can change the meaning of the final audio.
Clear answer
How do you translate audio without losing the context?
Use the transcript as an editorial checkpoint rather than treating it as invisible processing. Each source segment has a time range, and selecting it plays the related portion of the original audio when the source is available. That makes it practical to verify a name, abbreviation, quoted statement, or phrase affected by background noise. After corrections are saved, the workflow continues to translation and voice generation. Keep the original recording alongside the project and make sure you have ownership, a suitable license, or explicit permission to process it. The result is a more reviewable handoff than a one-click audio conversion.
Clear answer
What do you receive after translating an audio file?
The primary delivery is a translated M4A audio track. The project can also provide source and translated subtitle exports, including SRT, VTT, or ASS where supported by the task. This gives a team two useful review surfaces: listen to the translated track for tone and pacing, and inspect the text file for wording or terminology. If you plan to reuse the recording in video, a podcast editor, or a learning system, keep both outputs with the approved source. The audio translator is designed for spoken-content localization, not for removing watermarks, changing video imagery, or publishing a source you do not have rights to use.

Why timed review matters for spoken content
Spoken language contains interruptions, acronyms, overlapping speakers, and phrases that make sense only in the recording. A timed transcript lets an editor return to the exact moment before approving a translation. It is a small operational detail that protects high-value names, claims, and quotes from being carried into the final voice unchanged.
Keep terminology stable before you generate the voice
For recurring terminology, prepare an approved spelling and pronunciation list before review. Teams commonly need this for product names, course modules, researcher names, or organization names. The review stage is the right place to resolve those decisions because changing the source transcript after voice generation creates unnecessary rework.
When to use a separate video translation workflow
Use this page for a standalone audio file. If the source is a video and the target delivery needs on-screen subtitles, visual cleanup, or a localized video export, use the video translation workflow instead. Keeping that boundary clear helps each project start with the right source and deliverable.
Choose the right deliverable
Audio translation is not the same as transcription or text-to-speech
These workflows overlap, but they answer different delivery needs. Choose the format your listener or downstream editor actually needs.

Prepare with intent
Before you translate an audio file
A short preparation check makes the review stage more useful and keeps the final voice track easier to approve.
Use a recording you own, license, or are explicitly authorized to process.
Keep a clean source file and note speakers, names, and technical terms that need review.
Choose a target language and regional locale that fits the audience receiving the audio.
Listen to flagged or uncertain transcript segments before approving voice generation.
Where it fits
Built for audio that needs to travel well.
Audio can be ambiguous. The review stage is intentionally part of the workflow: it pairs editable transcript segments with source playback, rather than hiding the transcription behind a one-click export.
Make multilingual interviews easier for a distributed team to listen to and review without losing the original reference.
02
Courses and podcasts
Prepare an additional listening track for lessons, explainers, and episodic audio that needs a target-language audience.
03
Product narration
Adapt approved product audio for a new market while keeping terminology under editorial control.
Review before generation
A reviewable translation workflow

Common questions
Before you upload
Can I translate a recording with multiple speakers?+
Yes. Review the transcript segments and speaker labels before generating the translated voice, especially when speakers overlap or use specialized names.
Do I get a transcript too?+
The workflow provides a transcript review stage and can provide source and translated subtitle exports for the completed task.
What audio can I upload?+
The standalone workflow accepts common audio formats including MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, and WMA, up to 2 GB.
Can I choose the source language manually?+
Yes. Start with auto-detection or set the source language when you already know it, then verify it during transcript review.
Can I keep music or ambience in the result?+
The workflow includes an optional background-audio preservation setting for eligible member workflows; listen to the final mix before delivery.
Does this translate video too?+
No. This page is for standalone audio. Use the video translation workflow when the source or final deliverable includes video.
