Choose cloud recognition or approved local/offline capability based on quality, connectivity, privacy, and hardware.

Best for: Live producers, caption operators, audio engineers, broadcast engineers, and authorized event administrators.

Before you start

Audio, speech providers, multi-speaker features, and usage are governed by event permissions, plan entitlements, provider support, credentials or wallet, and browser/device compatibility.

  • Use the production event and supported browser/device.
  • Know the source language, speaker plan, latency target, output requirements, and fallback.
  • Test with representative voices, noise, pace, and the actual signal chain.

Step by step

  1. Define constraints. Languages, accuracy, latency, internet, privacy, cost, hardware, and offline duration.
  2. Evaluate cloud providers. Azure, Google Chirp 3, and Speechmatics offer different models/settings/coverage.
  3. Evaluate local capability. Confirm Desktop Operator version, downloaded model, language, hardware/CPU/GPU, and feature limitations.
  4. Test representative audio. Use actual microphones/noise/speakers.
  5. Test network failure. Determine which features continue and which translations/TTS/outputs require cloud.
  6. Measure resource load. Observe latency, thermals, memory, and battery on the production machine.
  7. Set primary/fallback. Document activation, transition, and quality expectations.
  8. Review data policy. Understand where audio/text is processed and retained.

What this unlocks: The configured audio and recognition path produces stable, attributable captions within the approved latency/quality target and has a tested recovery path.

Check your understanding

  • The selected mode meets the event’s language, latency, quality, privacy, and resilience needs on the actual hardware/network.

Common misconceptions

Local model unavailable

Install approved assets/version or use an entitled cloud provider.

Cloud disconnects

Use tested failover and preserve live state.

Local latency high

Reduce model/workload or upgrade hardware; do not promise unsupported performance.

Good to know

  • Offline does not mean every platform feature is offline.
  • Document model/version and license.
  • Follow privacy policy for both local and cloud processing.
