TTS generation
“Voice not available in your subscription”
Some HD or specialty voices require paid Azure tier (S0). Either pick a standard Neural voice or upgrade your Azure tier.
“Rate limit exceeded”
Either you're on Free tier and hit the 9-hour monthly cap, or your paid Azure tier's per-second cap was exceeded. Wait a minute and retry; if it's the monthly cap, upgrade or wait for reset on the 1st.
Audio generates but plays silence
Usually a local audio-device issue. Test other audio in Windows. Restart Speech Studio. If it persists, email support with the History log entry.
Transcription
Live mic doesn't pick up audio
- Check the selected input device in Speech Studio matches your actual mic
- Check Windows Settings → Privacy → Microphone — Kaizen Speech Studio must be allowed
- Try speaking closer to the mic; check levels in Windows Sound Settings
Transcript is gibberish
Wrong language selected. Check the language dropdown matches the spoken language.
Dubbing
Dubbing fails at “Uploading”
Your Blob Storage connection string isn't working. Re-verify in the Azure tab. Make sure the videos container exists and the container name in Speech Studio matches exactly.
Dubbing fails at “Translating”
Usually means the source language auto-detection got it wrong. Explicitly set the source language and retry. If problem persists, check Azure portal for the specific error.
“Rate limit” during dubbing
Azure Video Translation is strictly rate-limited. Wait a few minutes and retry. For high-volume needs, contact Microsoft for dedicated quota.
