Helm Order Monitor
Keep the order, read-back and rudder response aligned.
On-board speech recognition and available steering data support the bridge team during manual steering, without taking control of the vessel.
Order. Read-back. Response.
HOM follows one operational chain and checks the points where a communication or execution mismatch can develop.
Order issued
The pilot or navigator gives a standard helm order during manual steering.
Read-back recognised
The repeated order is checked for consistency with the order already captured.
Response checked
Available rudder and navigation data are used to assess whether the expected action follows.
Explore a defined mismatch.
Select an example to see the observed sequence and the local advisory. These examples reflect development logic; final signals and thresholds are installation-specific.
The recognised repeat-back does not match the captured order.
ORDER · PORT TEN / REPEAT · STARBOARD TEN
WRONGLY REPEATED
The bridge team is prompted to correct the closed-loop exchange before execution is treated as confirmed.
Rudder movement begins in the direction opposite to the confirmed order.
ORDER · PORT TEN / RUDDER · STARBOARD 4°
WRONG HELM
The confirmed command is compared with the available steering response and a local advisory is raised.
The confirmed order is not followed by the expected rudder movement.
ORDER · PORT TEN / RUDDER · UNCHANGED
CHECK THE RUDDER
The advisory draws attention to delayed, absent or inconsistent execution without controlling steering.
The monitored heading moves outside the configured band after a steady-course state.
ORDER · PORT TEN / REPEAT · STARBOARD TEN
CHECK THE COURSE
The check depends on configured inputs and thresholds for the intended installation and evaluation.
Speech and steering context, processed locally.
A bounded advisory subsystem designed to sit beside existing bridge equipment and procedures.
Microphone array
Far-field bridge speech capture
On-board ASR
Domain-adapted helm-order recognition
Order-state logic
Order, repeat-back and confirmation
Response comparison
Configured steering and navigation data
Local advisory
Visual and audio bridge prompt
On-board edge computer
Speech, command-state and comparison logic remain local to the installed evaluation system.
Configured inputs
Rudder angle, heading, speed and other available signals are mapped for the intended installation.
Bridge-specific setup
Acoustics, microphone position, phraseology, thresholds and nuisance behaviour are checked in context.
Advisory only
The HMI and audio prompt have no command path to the steering system.
REAL SHIPBOARD TEST
Shipboard test video
Tested where the order loop actually happens: on board.
The shipboard test shows the installed setup, bridge speech capture, the recognised helm-order sequence, available steering-data response and the local advisory display in a real bridge environment.

OPERATIONAL BOUNDARIES
Support the bridge team. Keep command responsibility clear.
HOM is designed as an advisory aid within existing bridge procedures, not as a steering or navigation-control system.
Instrumenting the command loop
- Recognising defined helm-order phraseology
- Checking order and repeat-back consistency
- Comparing the confirmed order with configured ship data
- Providing local visual and audio advisories
