Voice Commands

FSFO Voice Commands

This page lists the currently supported English FSFO v6 voice commands and phrase formats based on the live speech grammar and command handlers.

To start speech recognition, click the microphone icon in the top-right corner. When recognition is active, the icon turns green.

When a command includes numbers, speak each digit normally. Example: say two three zero for heading 230, or one two three four for squawk 1234.

Some commands accept aliases. This page lists the primary supported phrases plus the common alternates that FSFO currently recognizes.

Notes

• FSFO includes some internal normalization and recognition tolerance for a few phrases, especially around radio tuning and squawk entry. The primary user-facing phrases on this page are the ones you should document and recommend first.
• If a command is not working, confirm that speech recognition is active, the selected speech engine is configured correctly, and that the command category is not disabled in Settings.
• Radio and transponder commands can be blocked by the Disable Radio Cmds setting.
