Speech Studio Troubleshooting¶
This page covers common issues and their solutions. If your problem is not listed here, please contact [email protected].
Audio Generation Issues¶
No audio is generated after clicking Convert¶
Possible causes and solutions:
- No internet connection -- Speech Studio requires an active internet connection to communicate with Azure Cognitive Services. Check your network connection and try again.
- License not activated -- Ensure your license is active. Go to Settings and verify your license status.
- Azure keys expired -- If your Azure keys have expired, contact Kaizen Apps support for new keys.
- Firewall blocking connections -- Add Speech Studio to your firewall's allowed applications list. The app needs to reach Azure endpoints at
*.tts.speech.microsoft.com.
Audio sounds robotic or unnatural¶
- Ensure you are using a neural voice (voice names ending in "Neural")
- Check that punctuation is correct in your text -- the engine relies on punctuation for natural intonation
- Try a different voice; some voices perform better with certain types of content
Audio has unexpected pauses or timing¶
- Review your text for unusual spacing or formatting
- Remove extra line breaks between sentences
- Use SSML
<break>tags for intentional pauses instead of relying on whitespace
Installation Issues¶
Installer fails or crashes¶
- Ensure you are running Windows 10 or later (64-bit)
- Try running the installer as Administrator (right-click > Run as administrator)
- Temporarily disable antivirus software during installation
- Download a fresh copy of the installer from the Speech Studio page
Application won't launch¶
- Verify that .NET Desktop Runtime 6.0 or later is installed
- Check the Windows Event Viewer for error details
- Try reinstalling the application
License Issues¶
"Invalid license key" error¶
- Double-check the key for typos -- copy and paste directly from your email
- Ensure there are no extra spaces before or after the key
- Verify you are using the correct key for Speech Studio (not another Kaizen Apps product)
License deactivation failed¶
- Ensure you have an internet connection
- If you cannot deactivate on the old machine (e.g., hardware failure), contact support for manual deactivation
Performance Issues¶
Conversion is very slow¶
- Check your internet speed; slow connections directly affect conversion time
- For very long texts, break them into smaller segments
- Close other bandwidth-heavy applications
