What to check in your trial
Check model access terms and language support for alignment separately from basic speech recognition.
- Use a fixed dataset representing the language, accents, audio quality and speaker overlap expected in production. Record the exact model and configuration.
- Measure recognition quality, latency and failure behavior separately. Test reconnects, retries and incomplete audio in the intended API mode.
- Review regions, quotas, retention and request options. Confirm how optional features, channels and long-running jobs affect the bill.
