Intelligent Voice Activated Drone(s) for in-Vehicle Services and Real-Time Predictions2021-01-006304/06/2021
Today, commercially available drones have limited use-cases in the rapidly evolving community. However, with advances in drone and software technology, it is possible to utilize these aerial machines to solve problems in a variety of industries such as mining, medical, construction, and law enforcement. For example, in order to reduce time of investigation, Indiana State Police are currently utilizing ad-hoc commercial drones to reconstruct crash scenes for insurance and legal purposes. In this paper, we illustrate how to effectively integrate drones for in-vehicle services and real-time prediction for automotive applications. In order to accomplish this, we first integrate simpler controls such as voice-commands to control the drone from the vehicle. Next, we build smart prediction software that monitors vehicle behavior and reacts in real-time to collisions. Furthermore, we employ object recognition techniques through In-Vehicle Infotainment (IVI) systems to identify the surroundings

New Method Makes Computer Memory from Titanium OxideTBMG-3834001/01/2021
A team has developed a method to imbue computer chips that power machine-learning applications with more processing power by using a common material found in house paint in an analog memory device that enables highly energy-efficient machine inference operations. The material, titanium oxide, is a commonly made material used in house paint. It is an oxide, which means it already contains oxygen. Subtracting some of the oxygen creates oxygen vacancies that make the material electrically conductive. Those oxygen vacancies can now store electrical data, giving almost any device more computing power.
Editorial20AVEP07_0107/01/2020
For me, the June 19 announcement from Mercedes-Benz and the BMW Group that the two German powerhouses are placing their automated-driving joint-development program “on hold” pretty much closed the book on the irrational exuberance era of autonomous-vehicle hype. The projected economic ramifications of COVID-19 are only capping off a wave of reality that was sweeping through the AV development world. Anybody with sense always knew the runway was suspiciously short for wide swaths of AV investment and development. The inevitable cash desert coming in COVID's wake simply made the industry's famously venture capital-driven optimism undeniable.

Streamlined HMIs do more with less19TOFHP04_0804/01/2019
The phrase “less is more” has been a major part of human-machine interface (HMI) designs for several years as developers traded multiple knobs and buttons for cleaner input techniques. However, the push to simplify the control's look and feel is offset by the need to let drivers and operators manage more things, often with redundant input techniques. The growing number of electronic features and functions comes as vehicle buyers demand controls that can be learned quickly. This need to manage more complex tasks without much training marks a major change from the era when operators slowly learned how to maneuver mechanical controls. New designs will need to further simplify the vehicle environments designed to provide more digital functionality.

WHAT WE'RE DRIVING18AUTP10_0510/01/2018
Mercedes-Benz is fond of saying it cascades at least some of the S-Class' posh luxury and technology throughout its range. That's just what it has done for the fourth-generation A-Class, the nameplate that sits at the bottom of the brand's lineup. The new A-Class is heaped with cabin tech, in particular. Built on Mercedes' MFA2 front-wheel-drive platform, the A200 AMG Line version driven is well-connected, having the MBUX (Mercedes-Benz User Experience) touchscreen interface (and a touchpad), plus “Hey Mercedes” voice recognition.
Switching to comfort mode18TOFHP08_0808/01/2018
Switches, knobs and touch panels evolve to reduce operator fatigue. Programmability has become a central design element for engineers tasked with making work environments more comfortable for commercial-vehicle operators. Touchscreens continue to handle more functions, while switches, knobs and joysticks are all becoming more versatile as embedded electronics turn them into multi-function controls. There's a shortage of drivers in trucking and operators in off-highway, prompting a major focus on making sure that workers in both fields stay on the job. A range of control technologies play a major role in the effort to improve comfort for those who spend long hours working in cabs.

Memristors Enable Quick-Learning Neural NetworkTBMG-2856003/01/2018
Inspired by brains, neural networks are composed of neurons (or nodes) and synapses, which are the connections between nodes. To train a neural network for a task, a neural network takes in a large set of questions and the answers to those questions. In this process of what’s called supervised learning, the connections between nodes are weighted more heavily or lightly to minimize the amount of error in achieving the correct answer.

Analysis of Vehicle Voice Recognition Performance in Response to Background Noise and Gender Based Frequency2017-01-188806/05/2017
Voice Recognition (VR) systems have become an integral part of the infotainment systems in the current automotive industry. However, its recognition rate is impacted by external factors such as vehicle cabin noise, road noise, and internal factors which are a function of the voice engine in the system itself. This paper analyzes the VR performance under the effect of two external factors, vehicle cabin noise and the speakers’ speech patterns based on gender. It also compares performance of mid-level sedans from different manufacturers.

The Effect of HVAC Buffeting on Automatic Speech Recognition Systems2017-01-178106/05/2017
The design and operation of a vehicle’s heating, ventilation, and air conditioning (HVAC) system has great impact on the performance of the vehicle’s Automatic Speech Recognition (ASR) and Hands-Free Communication (HFC) system. HVAC noise provides high amplitudes of broadband frequency content that affects the signal to noise ratio (SNR) within the vehicle cabin, and works to mask the user’s speech. But what’s less obvious is that when the airflow from the panel vents or defroster openings can be directed toward the vehicle microphone, a mechanical “buffeting” phenomenon occurs on the microphone’s diaphragm that distresses the ASR system beyond its ability to interpret the user’s voice. The airflow velocity can be strong enough that a simple windscreen on the microphone is not enough to eliminate the problem. Minimizing this buffeting effect is a vital key to building a vehicle that meets the customer’s expectations for ASR and HFC performance. Systems design principles must be applied

The Effect of Vehicle Noise on Automatic Speech Recognition Systems2017-01-186406/05/2017
The performance of a vehicle’s Automatic Speech Recognition (ASR) system is dependent on the signal to noise ratio (SNR) in the cabin at the time a user voices their command. HVAC noise and environmental noise in particular (like road and wind noise), provide high amplitudes of broadband frequency content that lower the SNR within the vehicle cabin, and work to mask the user’s speech. Managing this noise is a vital key to building a vehicle that meets the customer’s expectations for ASR performance. However, a speech recognition engineer is not likely to be the same person responsible for designing the tires, suspension, air ducts and vents, sound package and exterior body shape that define the amount of noise present in the cabin. If objective relationships are drawn between the vehicle level performance of the ASR system, and the vehicle or system level performance of the individual noise, vibration and harshness (NVH) attributes, a partnership between the groups is brokered

Laser-Induced Graphene Enables Intelligent Artificial ThroatTBMG-2689105/01/2017
Researchers at Tsinghua University have developed an intelligent artificial throat based on laser-induced graphene. The intelligent device both detects and generates sound in a single unit. The biocompatible artificial throat, which attaches to the larynx, is designed to produce recognizable and controllable sounds. According to the researchers, led by Prof. Tian-Ling Ren in the university's Institute of Microelectronics, the device is a new application of graphene in the field of wearable electronics and is expected to have a significant impact in biology, speech recognition, and other fields.
Low-Power, Special-Purpose Chip for Speech Recognition in ElectronicsTBMG-2686305/01/2017
Automatic speech recognition is on the verge of becoming the chief means of interacting with computing devices. To address this, MIT researchers have built a low-power chip specialized for automatic speech recognition. Whereas a cellphone running speech recognition software might require about 1 Watt of power, the new chip requires between 0.2 and 10 milliwatts, depending on the number of words it has to recognize. That probably translates to a power savings of 90 to 99 percent, which could make voice control practical for relatively simple electronic devices, including power-constrained devices that harvest energy from their environments, or go months between battery charges.
The Impact of Microphone Location and Beamforming on In-Vehicle Speech Recognition2017-01-169203/28/2017
This paper describes two case studies in which multiple microphone processing (beamforming) and microphone location were evaluated to determine their impact on improving embedded automatic speech recognition (ASR) in a vehicle hands-free environment. While each of these case studies was performed using slightly different evaluation set-ups, some specific and general conclusions can be drawn to help guide engineers in selecting the proper microphone location and configuration in a vehicle for the improvement of ASR. There were some outcomes that were common to both dual microphone solutions. When considering both solutions, neither was equally effective across all background noise sources. Both systems appear to be far more effective for noise conditions in which higher frequency energy is present, such as that due to high levels of wind noise and/or HVAC (heating, ventilation and air conditioning) blower noise. Microphone location was also shown to have a substantial effect on the

Systems Engineering Approach for Voice Recognition in the Car2017-01-159903/28/2017
In this paper, a systems engineering approach is explored to evaluate the effect of design parameters that contribute to the performance of the embedded Automatic Speech Recognition (ASR) engine in a vehicle. This includes vehicle designs that influence the presence of environmental and HVAC noise, microphone placement strategy, seat position, and cabin material and geometry. Interactions can be analyzed between these factors and dominant influencers identified. Relationships can then be established between ASR engine performance and attribute performance metrics that quantify the link between the two. This helps aid proper target setting and hardware selection to meet the customer satisfaction goals for both teams.

The sensor resembles a small Band-Aid®, weighs less than one-hundredth of an ounce, and can gather continuous physiological data.
SAE Convergence 201616AUTP11_0111/01/2016
Talk of the healthy aspects of disruption mingles with SAE's renowned technical emphasis to foster the auto industry's continuing evolution toward electrification and autonomy. The auto industry is at the moment ravenous for discussion and guidance regarding the ongoing integration of electronics into vehicle development-but particularly regarding the almost daily deluge of news and speculation about vehicle automation. SAE's 2016 Convergence conference supplied a diverse forum for those conversations while providing a new format that grouped each of the conference's three days into a distinct subject-matter theme. From an insightful, consumer-focus keynote address from Ford's Raj Nair, Executive Vice President, Product Development and Chief Technical Officer, to technical sessions that explored everything from trends in human-machine interface to supply-chain transformation, Convergence once again was the rallying point for technical and strategic discussion at a high level.

Sub-Audible Speech Recognition Based on Electromyographic (EMG) SignalsTBMG-2390802/01/2016
Sub-audible speech is a new form of human communication that uses tiny neural impulses (EMG signals) in the human vocal tract instead of audible sounds. These EMG signals arise from commands sent by the brain’s speech center to tongue and larynx muscles that enable production of audible sounds. Sub-audible speech arises from EMG signals intercepted before an audible sound is produced and, in many instances, allows inference of the corresponding word or sound. Where sub-audible speech is received and appropriately processed, production of recognizable sounds is no longer important. Further, the presence of noise and of intelligibility barriers, such as accents associated with the audible speech, no longer hinder communication.

Quantifying Hands-Free Call Quality in an Automobile2015-01-233506/15/2015
Hands-free phone use is the most utilized use case for vehicles equipped with infotainment systems with external microphones that support connection to phones and implement speech recognition. Critically then, achieving hands-free phone call quality in a vehicle is problematic due to the extremely noisy nature of the vehicle environment. Noise generated by wind, mechanical and structural, tire to road, passengers, engine/exhaust, HVAC air pressure and flow are all significant contributors and sources of noise. Other factors influencing the quality of the phone call include microphone placement, cabin acoustics, seat position of the talker, noise reduction of the hands-free system, etc. This paper describes the work done to develop procedures and metrics to quantify the effects that influence the hands-free phone call quality. It will be shown that a listening study of using 49 evaluators, indicated that the ETSI EG 202 396-3EG (VoIP Standard) for SMOS (Speech Mean Opinion Score) and

Technical and personal issues make it challenging to link smartphones to vehicles. Human-machine interfaces (HMIs) are quickly evolving as smartphones and apps enter vehicles. Developers are allowing multiple ways for drivers to interact with apps and phones, knowing that a well-designed HMI can be a significant differentiator while a problematic HMI can become fodder for highly-publicized criticism. The tightening link between cars and consumer devices is challenging vehicle designers who must adopt consumer technologies for control. Most executives agree that a range of control and display technologies will be needed to manage apps and phones.

Bright outlook for glass cockpits12AERD0215_0102/15/2012
Cockpits are adopting larger screens and touch input, using modularity to ease upgrades. Growth in the number of planes flying globally, combined with a declining number of skilled pilots, is prompting a change in cockpits designed to make flying simpler. Larger displays make it possible to show data that is relevant, while touch control is being used to reduce clutter by eliminating buttons. Before these techniques are employed to reduce the cognitive workload, they're heavily vetted. As engineers devise techniques that guide pilots to the right actions and migrate to more intuitive controls, many are delaying the adoption of voice controls. Things are also changing behind the display panels as more modular systems are used so it's easier to update systems as new features and functions become available.

On driver distraction, the ‘eyes’ have it11AEID0621_0106/21/2011
There is disagreement among researchers about how significant a problem mind-off-the-road is, but everyone agrees it's a good idea to look where you're going. Keeping one's attention trained entirely on operating the vehicle is asking too much of the average person, research suggests. Racecar drivers can stay focused, but the rest of us generally have something else on our minds while we're tooling down the highway. That particular state of affairs on our roadways, and in our minds, causes less worry for Ford driver distraction expert Louis Tijerina than it might for the average person. Were it not for hard data supporting his attitude, he might not have arrived at this seemingly counterintuitive view of the matter.

Speech Acquisition and Automatic Speech Recognition for Integrated Spacesuit Audio SystemsTBMG-870011/01/2010
A voice-command human-machine interface system has been developed for spacesuit extravehicular activity (EVA) missions. A multichannel acoustic signal processing method has been created for distant speech acquisition in noisy and reverberant environments. This technology reduces noise by exploiting differences in the statistical nature of signal (i.e., speech) and noise that exists in the spatial and temporal domains. As a result, the automatic speech recognition (ASR) accuracy can be improved to the level at which crewmembers would find the speech interface useful. The developed speech human/machine interface will enable both crewmember usability and operational efficiency. It can enjoy a fast rate of data/text entry, small overall size, and can be lightweight. In addition, this design will free the hands and eyes of a suited crewmember.

Integrated Spacesuit Audio System Enhances Speech Quality and Reduces NoiseTBMG-586711/01/2009
A new approach has been proposed for increasing astronaut comfort and speech capture. Currently, the special design of a spacesuit forms an extreme acoustic environment making it difficult to capture clear speech without compromising comfort. The current system, called Communication-Cap-based Audio (CCA), relies on a single microphone placed close to the subject’s mouth. While this results in clear audio, it also has problems: wire fatigue, blind mating, interference with food/drink, need for custom communication caps, and not being able to adjust the microphone during extravehicular activities.

Services are expected to rise as technical collaboration and available bandwidth increase. The increasing growth in the number of infotainment options available in vehicles over the past few years shows no signs of quieting down. Telematics services are expected to stretch far beyond safety and security, letting drivers stay connected to the Internet so they can bring in nearly any diversion they want. Telematics connections are expected to grow swiftly over the next few years, as more functions are available on more models. Automakers are expanding both the number of models that have wireless links and the number of applications they can access. Safety, security, and diagnostics, not infotainment, are currently the mainstays of telematics.

Processing Electromyographic Signals To Recognize WordsTBMG-519505/01/2009
A recently invented speech-recognition method applies to words that are articulated by means of the tongue and throat muscles but are otherwise not voiced or, at most, are spoken sotto voce. This method could satisfy a need for speech recognition under circumstances in which normal audible speech is difficult, poses a hazard, is disturbing to listeners, or compromises privacy. The method could also be used to augment traditional speech recognition by providing an additional source of information about articulator activity. The method can be characterized as intermediate between (1) conventional speech recognition through processing of voice sounds and (2) a method, not yet developed, of processing electroencephalographic signals to extract unspoken words directly from thoughts.

User-centered Human-Machine-Interaction (HMI) Design for Automotive Systems2008-21-000410/20/2008
Multimedia systems, GPS navigation, entertainment, and communication (infotainment) have become increasingly popular in today's cars. On one hand, these systems offer a desirable amount of comfort and convenience. On the other, the representation of information on displays and navigation through these virtual worlds leads to increased driver distraction within a constantly changing environment that could be dangerous to road safety. For this reason, Human-Machine-Interaction (HMI) Design needs to be addressed. This paper will present a problem-driven, user-centered cognitive approach. It also shows how HMI Design transfers research findings into efficient product development. There is a very complex relationship between the user, the interface and the traffic environment. Psychological factors, the driving situation, and interface properties affect drivers' behavior. Design parameters for interaction concepts will be shown.

Touch input and smarter knobs help drivers control a growing array of functions and devices. There is one thing that the developers of human-machine interfaces agree on: If someone figures out a way to let the driver control the many tasks facing drivers in this era of connectivity, that person is going to become very rich. Portable navigations systems, phones, MP3 players, and other devices increase the number of functions drivers already have to handle, creating big headaches for developers who want to reduce driver distraction. Add in the vagaries of human preferences and you have enough challenges to keep engineers busy for years.

Intelligent Navigation for Music and Media from Multiple Sources2006-21-005210/16/2006
The adoption of digital media in the car is rapidly growing; with that are an increasing number of disparate media sources such as portable media players, satellite radio, and HD radio. Media sources utilize various user access models creating a critical standardization problem in the entertainment sub-system design making navigating media in the car not only difficult but a dangerous driver distraction. Each media source creates different metadata and uses slightly different user models contributing to the overall lack of metadata standardization and can result in inaccurate or missing tag information, and multiple categories for the same piece of media. A band like “The Rolling Stones” may be categorized as “Classic Rock” on a satellite system but as “Rock” on a portable MP3 player plugged into the entertainment subsystem. In the car, lack of standardized metadata creates a dangerous environment as the consumer is forced to manually navigate through media; a serious driver

The MP3/iPod jacks underscore the wave of the future, providing a way for consumers to move between their home and vehicle without sacrificing anything for the benefit of mobility Design engineers must devise schemes that mix the decade lifetime of a vehicle with rapidly evolving technologies such as the iPod, which was not introduced until late in 2001, when designs for most of the vehicles on the highway today were already cast in steel.
