LocalVocal OBS Plugin Crashes? Here's Why + Fix

LocalVocal is a free OBS plugin for captions, but it crashes frequently on OBS updates and consumes significant local CPU/GPU. The fix is to switch to a cloud-based browser source tool like StreamTranslate, which never crashes and has 2x better latency.

Why LocalVocal Crashes

LocalVocal is an OBS plugin compiled against specific OBS versions. When OBS updates, LocalVocal breaks until the developer recompiles it. This happens every few months, causing downtime mid-stream.

Performance Issues

LocalVocal runs speech recognition on your local PC, consuming 10-20% CPU and 5-10% GPU. This degrades stream quality. Cloud tools like StreamTranslate use zero local resources.

The Better Solution: Cloud-Based Browser Source

Switch to StreamTranslate: no crashes, 1.8s latency (vs. LocalVocal's 4-8s), 28+ languages, dual-language option, zero local CPU impact.

Migration Steps

  1. Disable LocalVocal in OBS
  2. Sign up at streamtranslate.live/control
  3. Copy the overlay URL
  4. Add as Browser Source in OBS
  5. Stream normally — LocalVocal issues are gone
