Brief summary

In NVDA Settings -> Speech, when the synthesizer is set to "Microsoft Speech API version 5 (32 bit)", several control labels appear to be hard-coded in English or otherwise not exposed to NVDA's localization system. As a result, these labels are not translatable into other NVDA languages.

Labels in question:

• Voice
• Rate
• Rate boost
• Pitch
• Volume
• Use modern audio output system (WASAPI)

Steps to reproduce

1. Set NVDA's language to something other than English (e.g. Finnish) and restart NVDA if asked.
2. Open the NVDA menu -> Mukautukset -> Asetukset.
3. Open the "Puhe" category.
4. Set the "Synthesizer" to "SAPI 5 (32-bittinen)".
5. Check the labels listed above.

Actual behavior

The labels listed above remain in English.

Expected behavior

These labels should be localizable and therefore translatable like the rest of the NVDA Settings UI.
