Embedded Speech Recognition Development

Custom Development of Embedded Speech Recognition Systems

Utilizing Existing Certified Embedded Platforms

Many avionics manufacturers have hardware systems that have already passed all necessary flight deck certifications.  When possible, based on CPU speed and memory capacity, MatrixHCI can develop custom speech solutions that run on pre-certified hardware systems that our customers have already invested in certification.

Many of these hardware systems also utilize DSP processors and FPGA capabilities, and some run with RTOS operating systems and some do not.  MatrixHCI can evaluate your current software and hardware products and components and help determine the feasibility of using existing hardware systems to perform our intelligent speech recognition functions.

We can provide embedded solutions that run on RTOS operating systems or even develop a system that runs without an OS, if necessary.

Let MatrixHCI help you decide the best implementation design for your current or upcoming speech recognition needs.


DO-178 Compliant Real Time Operating Systems (RTOS) Integration

“As the cockpits get more sophisticated, as displays get more sophisticated, as everything is more digitally controlled, there’s more and more software,” says David Kleidermacher, Chief Technology Officer with Green Hills Software, Santa Barbara, CA, a manufacturer of DO-178 Real-Time Operating Systems.

“One thing we always say to people is that it is possible to build absolutely reliable software that’s very complicated … [but] it needs to be right.  They need to be able to depend on an operating environment they can trust.

Having a commercial-off-the-shelf solution that’s proven for so long and has been flying on so many other aircraft allows them to meet that goal quicker.”

The Panoramic Cockpit Display of the F-35, provided by L-3 Display Systems, Alpharetta, GA, uses both the Green Hills Software Integrity-178B and the LynuxWorks LynxOS-178 Real-Time Operating Systems (RTOS), L-3 said.

MatrixHCI can develop custom speech interfaces for avionics in flight decks that sit on top of DO-178 certified RTOS operating systems, such as Green Hills Software, and integrate the developed speech recognition interface into your existing software system.

Our experience in aviation-related software systems and our deep understanding of flight decks, flight phases and aircraft operations, and pilot interface needs, position us as your logical choice for the development of intelligent speech recognition software systems.

Embedded Systems

In a survey conducted this year, VDC Research Group of Natick, MA, determined that the  “average embedded military/aerospace project is expecting an increase over 28 percent in size of total lines of code over future upcoming projects.”  That amount exceeds the 22 percent average increase for the overall embedded software market.

On aircraft, the use of embedded software has “grown exponentially” over the last 20 years as “analog systems have been replaced by digital systems.”  The operational flight program of the F-35 Lighting II or Joint Strike Fighter, for example, will have at least 5 million lines of software code.  That is more than twice the total of the F-22 Raptor and four times that of the F/A-18E/F according to a Government Accountability Office (GAO) report in March.

As embedded digital-based flight deck instrumentation becomes more pervasive in flight decks, the need to quickly and easily navigate through the many screen displays and system processes ever becomes a challenge to a pilot’s concentration.

Speech Recognition in the flight deck will become an interface that pilots will come to rely upon more and more as flight decks become more complicated.  MatrixHCI can design and deploy speech recognition based interface systems for the flight deck that can be custom embedded in flight deck instrumentation.

We can even speech enable existing flight applications and pilot functions supplying avionic vendors and manufacturers with add-on components that provide intelligent speech interfaces.  Please contact MatrixHCI for a free consultation on how we can help meet your speech recognition interface needs in the flight deck.
