Verify StreamTranslate accuracy, timing, and positioning before your next live stream. Eight-step test process to ensure captions are perfect before you go live.
Start Free TrialTesting your stream captions before going live saves you from discovering problems in front of your audience. A few minutes of pre-stream testing gives you confidence that captions are accurate, correctly positioned, and appearing with acceptable latency. It also lets you verify that game-specific vocabulary is recognized correctly and that your audio setup is delivering clean input to our industry-leading speech AI.
The process below takes about 10 minutes and covers accuracy, timing, audio environment, and mobile readability — the four key quality dimensions of live stream captions.
Log in to streamtranslate.live and navigate to your control panel. Verify your source language and translation settings are configured correctly.
Make sure your StreamTranslate browser source is present in your scene and set to visible.
Click 'Start Virtual Camera' in OBS or use OBS's built-in preview mode to see your stream output without going live.
Say your typical intro, some game-specific vocabulary (champion names, callouts), and some longer sentences to test accuracy across your content types.
Verify captions appear within about 300ms of you speaking. If there's significant delay, check your internet connection.
Simulate your typical streaming environment — keyboard clicking, fans running — to see how captions handle background noise.
Read the captions as they appear. Note any recurring misrecognitions and adjust your microphone position or OBS audio settings if needed.
Use a phone or tablet to view your stream preview and verify caption text is readable at smaller screen sizes.
Use OBS's Virtual Camera or Preview mode to see your stream output locally. StreamTranslate captions will appear in the preview exactly as they would on a live stream.
Test with your typical intro phrases, game-specific vocabulary (champion names, callouts), and longer explanatory sentences to cover the range of content you normally produce.
Captions should appear within 300-500ms of you speaking. If you notice a 1+ second delay, check your internet connection speed and stability.
Yes. StreamTranslate's free trial gives you full access to test captions during real streams and local preview sessions before committing to a paid plan.
Move your microphone closer, enable OBS noise suppression, and verify your source language setting is correct. Game vocabulary accuracy also improves with clearer audio input.
