StreamTranslateLet viewers follow your code and your explanation
Your editor shows what changed. Captions help viewers follow why you changed it. Add translated subtitles to live coding sessions, debugging walkthroughs and programming tutorials while keeping the code visible.
Free Plan: 3 active streaming hours every month. Card required; no payment unless you upgrade.
Give the explanation its own space
A coding stream has two things to read: your editor and your narration. Reserve a caption band beside or below the editor instead of laying subtitles over the active line. Leave room for the terminal, autocomplete menu and error messages you use during the session.
- Your microphone
- Live translated captions
- Browser Source in OBS
- Editor and captions in one broadcast
For an international audience, choose a subtitle language that matches the viewers you expect. Start with one readable caption output before adding more text to an already busy screen.
Set up the coding scene
Prepare the editor capture
Add your editor window to OBS or Streamlabs. Increase the editor font and preview the terminal at the size viewers will see.
Choose the caption input
In StreamTranslate Control, choose your spoken and subtitle languages. Select the microphone under Audio Source and run Mic check.
Add the Browser Source
Copy your caption URL into a Browser Source. Match the source dimensions to your canvas and place it above the editor capture in the Sources list.
Record a local sample
Press GO LIVE in Control, keep the tab open for browser-microphone mode, and make a short OBS recording. Check both the explanation and the code before broadcasting.
Make technical speech easier to follow
Rehearse the words that define your session: framework names, APIs, acronyms and project terms. Say unfamiliar names clearly the first time. Expand an acronym before using it repeatedly, and pause between an instruction and a long identifier.
If you say “set user ID to null,” keep the actual identifier visible in the editor. Captions may render that as ordinary language or translate part of the phrase. Put the exact command in chat or a visible note when viewers need to copy it.
StreamTranslate does not promise a user-editable programming glossary or perfect preservation of code syntax. A brief vocabulary check is more useful than assuming every technical term will survive transcription and translation unchanged.
Protect the parts viewers need to read
- Editor
- Keep the active line and relevant context away from the caption band.
- Terminal
- Leave commands and error output unobstructed. Move the caption band if a demonstration changes the layout.
- Caption contrast
- Use readable text with a contrasting background or outline, especially when switching between light and dark editor themes.
- Scene changes
- Include the caption source in coding, browser-demo and camera scenes. Check each transition in your rehearsal.
Review the recording in a small player as well as full screen. If the editor and captions compete, enlarge the code or simplify the scene before increasing the amount of caption text.
Rehearse one real debugging moment
Introduce the problem, read an error, explain a change, run a command and describe the result. Listen back for keyboard noise covering your voice. Check whether captions remain readable when your autocomplete menu or terminal opens.
A correction spoken aloud can help viewers recover from a mistranscribed term. Keep the editor visible as the authoritative record of the code. Stop the caption session in Control when the rehearsal or broadcast ends.
StreamTranslate supports 65 live languages. Free Plan: 3 active streaming hours every month. Card required; no payment unless you upgrade. Paid streaming starts with Starter at $14.99/mo; compare plans against the length and frequency of your coding sessions.
Questions about coding stream captions
Will captions preserve variable names and code punctuation?
Not reliably enough to use them as executable code. Live transcription and translation process speech; keep exact code, commands and identifiers visible in your editor or a text note.
Can I caption a coding stream in Streamlabs?
Yes. Add your StreamTranslate caption URL as a Browser Source in Streamlabs, place it above the editor capture and rehearse the layout before broadcasting.
Do I need screenshots to follow the instructions?
No. The guide names the controls and source order to use. Build the scene in your own software and inspect a short local recording.
Does StreamTranslate read my code editor?
This setup captions the audio input you select. It does not read the editor, infer your source code or automatically translate the code displayed on screen.
