How to translate speech in real-time during video calls and live events

How to translate speech in real-time during video calls and live events

This task can be performed using Palabra.ai

Palabra.ai is a real-time AI speech translation platform

Prepare real-time call translation

Confirm the spoken languages, audience output needs, and meeting or broadcast audio path before going live. Real-time translation works best when each speaker uses a clear microphone and the translated feed returns through a separate channel.

Connect the translation service to the call or event workflow, select source and target languages, then test a short conversation. Add names and specialist terms to a glossary, check timing and volume, and brief speakers to pause between turns.

  5. Save up to 90% on translation costs compared to hiring human interpreters while still getting professional-quality results for your calls and events

More about pre-event testing

Run a rehearsal with the actual microphones, network, speakers, and terminology. Speech-to-speech translation can sound accurate in a quiet test but fail when people overlap or room audio echoes.

  • Test fast speech, accents, names, and numbers.
  • Keep translated audio out of the source microphone to prevent feedback.
  • Assign someone to monitor delay and use a backup audio channel if quality drops.
