Test language code pronunciation

Test Procedure

• Voiceover on macOS - default settings - switch on VO (Cmd-F5) and use Control-Options-Right Arrow to read page
• NVDA - default settings with Preferences->Settings->Speech option set to eSpeak (default Windows OneCore needs additional language packs to switch voices)
• JAWS - default settings

Notes

• Language codes like nl-BE-NL are treated as nl-BE in Voiceover
• Voiceover has better multi-language support than NVDA, and NVDA is better than JAWS
