The Microphone

The vocal interaction portion of PACX has two primary features. The first is the ability to pre-fill the interaction menu with what it heard from your announcement. The second is to allow playback of your recorded audio through a public address style filter (this is an option).

After PACX has processed your spoken audio, it will open the interaction menu, automatically filling in the menu based on what you said. If it were able to identify the announcement, it would show a preview of what was detected and provide a chance to modify the announcement if needed. When you are ready, or when the auto-accept time has passed, the announcement will be made. Pressing the Escape key while the “Listening” popup is open will cancel vocal interaction.

A “General” type of “Public Address” announcement type exists as well. This is intended to be used when giving a public address via the vocal interaction system that is not one of the other types. It does not have any effect on the passengers (outside of potentially waking them up if they were asleep).

Vocal recognition uses your system default microphone. The recognition quality can be improved by using Windows Speech Recognition training.
