Voice-Check ©
Talking Aviation Checklist Application
With Voice Recognition

Online Users' Guide

General Requirements VoiceCheck is designed for phones and tablets with Android version 2.2 ("Froyo") operating systems or higher. Android's default Text-To-Speech feature, pre-installed on most phones, is used by the application's TALK feature. Inexpensive 3rd party Text-To-Speech voices can be purchased and downloaded to change Android's default voice.

Voice recognition requires a data link, either cell phone or wifi, for Google's voice recognition service. Therefore LISTEN mode should not be selected when in flight outside of cellphone coverage. Since most checklist procedures are performed with wheels on ground 'Listen' mode should be available for most procedures and at most airports.

Section 3. Talk Mode

Both the top checklist menu and emergency checklist menu display a TALK switch. Talk mode (and Listen mode) support Bluetooth headsets. See section 11 for enabling Bluetooth.

Please refer to the next section for how TALK mode works in emergency procedures.

After selecting a normal checklist with TALK turned on Voice-Check performs as follows:

  • Checklist name is announced
  • Checklist item #1 is announced
  • Checklist item is repeated every 10 seconds until item is tapped (on screen)
  • When item is tapped, Voice-check verbally acknowledges checked item, then announces next item.
  • If item is not checked after 5 verbal repetitions Voice-Check will announce "Wait Mode" and stop repetitions.
  • When in Wait-mode touching anywhere on the screen will wake up device.
  • Tapping the current check-item when in Wait-mode will complete that check item.

Section 4. Emergency Procedures

To ensure reliability LISTEN mode is not available for emergency checklists. When TALK mode is OFF emergency checklists operate the same way as normal checklists. Pressing the Android's menu button will bring up the checklist menu window, just as with normal checklists.

TALK Mode in Emergency Lists

In TALK mode emergency check items are announced one after the other in a loop. Check items can be checked at the screen as normal, but audio will not be effected. The Android's menu button is disabled when TALK mode is enabled for an emergency list. Audio can be turned off by using the Android's back button to go back to the emergency list menu.

Editing Emergency Lists
Make sure that "Talk" function is turned off to edit emergency procedures. Open the procedure from the Emergency Lists menu and then press the menu button on your Android. Select "Edit List" key.

Section 5. LISTEN Mode (voice recognition)

In LISTEN mode Voice-Check will accept voice commands during checklist procedures. (Cell or wifi coverage required.)

At the top checklist menu tap LISTEN key to turn on LISTEN mode. TALK mode will automatically engage when ever LISTEN mode is selected.

When the checklist is started VoiceCheck will announce the checklist name - then announce the first check item. For example:

"Checklist for PreFlight Cabin"
... (pause)

"Aircraft Docs ... In Cabin"
After announcing a check item, Voice-Check will issue a BEEP tone and a "Speak now" window will show on the screen. Wait for the BEEP before speaking out your voice command.

Voice-Check will accept the following voice commands:
  • CHECK: check this item as completed
  • AGAIN: repeat current check item
  • WAIT: go into 'wait mode' (pause operation)
  • QUIT: stop operation and go back to main menu
Voice recognition may vary depending on pilot's individual voice tone and character. Therefore alternative commands are accepted:
  • Check = Next = Done = Okay = Roger = Affirmative
  • Repeat = Say Again = Again
  • Wait = Stop

Most check items will, of course, take some time to complete. Therefore the "Speak now" window will repeat several times to allow pilot time to complete the check item. This will be heard as a repeated BEEP every 20 to 30 seconds. After completing a check item, wait for a BEEP prompt and then say "Check" to proceed to the next item.

If Voice-Check does not recognize your voice command it will ask "Say Again." In this case wait for the BEEP prompt and repeat your command.

After 5 repeated beeps (approximately 3 minutes) Voice-Check will go into WAIT mode. To wake up Voice-Check tab on the highlighted check item on screen.

Section 6. Noise Cancellation

Pilots often ask how well Voice-Check's voice recognition works in the cabin during engine runup procedures. Because most aviation headset microphones include noise cancellation hardware recognition works much better than you might expect. Speak loudly and closely into non-cancelling microphones to overcome environmental noise.

Voice-Check: General Description

Voice-Check highlights and enlarges the current check-item to make sure you don't accidentally skip a step. Tap on the highlight (or use voice commands) and the next check-item is automatically presented.

With use of an inexpensive cell phone headset the voice command feature is especially useful for nearly hands-free exterior inspection. Put Voice-Check into "Listen" mode and stow your phone in a pocket. After announcing the current check item Voice-Check emits a "beep" cue. Cues repeat at 5 second intervals for 30 seconds or until it hears a voice command. Say "Check" after a cue and Voice-Check acknowledges check item, then announces the next. Say "Again" and Voice-Check repeats current check item. Say "Wait" and Voice-Check pauses until the touch screen is tapped (wait mode). If Voice-Check doesn't identify your voice command it announces "say again."

Cell or wifi linkage is required for voice recognition of voice commands. For emergency procedures in "Talk" mode Voice-Check vocalizes each step and repeats in a loop. A cell phone adapter for your aviation headset is recommended for using voice features in the cockpit. A simple cell phone headset or ear-buds are suitable for using voice features during exterior inspection.

Free Evaluation

Pilots are encouraged to evaluate Voice-Check by installing our free demo version.

Fully Customizable

Voice-Check installs a set of generic, 172 type checklist templates. Customize the templates easily, either on your Android or our online editor. Remember to use the "Text File" feature of our editor to download a text version of your checklist. Use the text file in a word processor for printing a paper backup copy of your checklist. For safety reasons keep this paper backup copy available in case of cellphone battery failure.
