You can review an individual dubbed line and request a change to its translation or delivery in Ollang, the AI language execution layer. The important distinction is between targeting a revision request and assuming that only one audio segment will be processed. A change to one line may affect subtitles, timing, or the surrounding video.
This walkthrough explains how to identify the issue, give reviewers enough context, and approve the updated result. If you have a dubbed order ready to review, sign in to Ollang.
Locate the Line That Needs a Translation or Delivery Change
Start at the moment a reviewer notices a problem. Record the video, target language, approximate timecode, speaker, and current wording. If the concern is delivery, describe what you hear: a product name pronounced incorrectly, a pause that changes the meaning, or a tone that does not suit the scene.
Then check more than the audio. Compare the source speech, source caption, translated subtitle, dubbed line, and any relevant on-screen text. A spoken error may begin with an inaccurate caption. A correct translation may instead sound wrong because of pronunciation or pacing. Identifying where the problem begins helps the team request the right change.
Ollang Agentic STT is available within the speech-to-text workflow. Visual STT can capture on-screen text, while Visual Translation supports its localization. Those sources of context matter when a speaker says “select this option” while pointing to a labeled control. Reviewing the spoken line alone may miss a conflict with what viewers can see.
Keep the issue record compact. Include:
- Location: Video, language, approximate timecode, and speaker.
- Current output: The relevant caption, subtitle, and dubbed wording.
- Problem: The specific meaning, pronunciation, tone, or timing concern.
- Requested outcome: What the audience should understand or hear.
- Context: Adjacent dialogue and relevant on-screen text.
This is enough to distinguish a correction from a general preference. It also gives the next reviewer a way to find and assess the same moment.
Specify the Revision Without Losing Its Surrounding Context
A useful request says what must change and what must stay the same. State the intended source meaning, provide preferred target-language wording if you have it, and identify any fixed terms. If wording is flexible, say so. A linguist may need a shorter phrase to fit the available time without changing the meaning.
Be specific about the type of issue. An accuracy correction is different from a tone adjustment; a pronunciation change is different from a request to rewrite the subtitle. For example, “Use the approved product name and keep the instruction direct” gives a reviewer clearer direction than “Make this line sound better.”
Include the lines before and after the revision. A pronoun may refer to an object shown earlier, or a response may depend on how the preceding line is phrased. When speakers alternate quickly, identify whose line is changing so the reviewer can check voice and conversational continuity.
Ollang supports translation memories and custom instructions. Use them for terminology or brand guidance that should carry across an order, rather than repeating the same note in separate requests. For a multilingual release, write one explanation of the source issue, then allow each language reviewer to resolve grammar, natural phrasing, and timing in context. Equal meaning does not require identical sentence length.
If the concern is voice delivery, describe the desired result without assuming a particular synthesis method. Ollang supports voice prompting and voice cloning, but a request for a calmer or clearer line is not automatically a request to clone a voice. Obtain the appropriate permission before using someone’s voice for cloning.
Before sending the request, check that it answers four questions: What is wrong now? What must the audience understand? What surrounding context limits the change? What should the reviewer check afterward?
Check Timing, Voice Continuity, and the Resulting Video
Review the revision in playback, beginning before the affected line and continuing through the next speaker turn. That short stretch can reveal a pause, interruption, or shift in tone that is difficult to judge from a transcript or isolated audio clip.
Match the check to the dubbing style. For lip sync, compare the delivery with visible mouth movement. For overdub, listen for whether the translated speech remains clear alongside the original audio. If the order includes audio description, check whether the revised wording fits the surrounding narration and available space.
Next, compare the dub with its subtitle. They do not need identical wording, but they should communicate compatible meaning. Check any on-screen labels or instructions as well. Visual STT and Visual Translation can help teams account for text that appears in the video rather than in the speech transcript.
Listen for voice continuity across nearby lines. The speaker should remain recognizable within the scene, and the delivery should suit the content. A safety instruction may call for a different tone from a promotional line. Finally, watch the resulting video: an audio change that works in isolation can still conflict with a title card, demonstration, or speaker transition.
The table below compares review methods, not vendors. It shows why an individual-line request should end with a check of the full viewing experience.
| Review method | What it helps the reviewer check |
|---|---|
| Ollang execution layer | Connected caption, translation, dubbing, and video output within an orchestrated workflow, with Review Gates available for human input. |
| Text-only review | Wording and terminology; audio timing and delivery still need a separate check. |
| Audio-only review | Pronunciation and voice delivery; subtitles and visible text still need a separate check. |
| Final-video review | How speech, subtitles, timing, and visuals work together for the viewer. |
