This book was released on 2024-03-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automatic Speech Recognition and Understanding (ASRU) has the potential to reduce air traffic controllers' (ATCos) workload and to enhance air traffic management (ATM) safety. Automatic Speech Recognition (ASR) transforms voice signals into a sequence of words, e.g., "speed bird four one six descend flight level one two zero". Automatic Speech Understanding extracts the meaning from this word sequence, e.g., that the aircraft with the callsign "BAW416" should "DESCEND" to roughly "twelve thousand feet". The Special Issue contains 12 articles authored by 54 different authors, working for 23 institutions that are located in 13 countries on four continents. These articles discuss (a) ontologies for modeling words and semantics, (b) the extraction of aircraft callsigns and complex commands, (c) ASRU support for ATCos through callsign highlighting, the filling of aircraft radar labels and flight strips for approach, tower, and apron environments, (d) supporting simulation pilots, (e) speech activity detection, speaker role classification, natural language processing, English language identification, (f) combining ASRU with surveillance data, (g) joining speech and gaze data, and (h) a safety assessment.

This book was released on 1990 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, the Air Traffic Control (ATC) system relies primarily on verbal communication between the air traffic controllers and the pilots of the aircraft in the controlled airspace. Although a computer system exists that processes primary radar, secondary radar, and flight plan information, the information contained within the verbal communications is not retained. The introduction of Automatic Speech Recognition (ASR) technology would allow this information to be captured for processing. The research presented in this paper examines the feasibility of using ASR technology in the Air Traffic Control environment. The current status of the technology is assessed. Problems that are unique to ATC applications of voice input are identified. Since ASR technology is inherently a part of the man-machine interface between the user and the system, emphasis is placed on the relevant human factors issues. A man-machine model is presented which demonstrates the use of mixed input modalities, automatic error detection and correction techniques, and the optimal use of feedback to the controller. Much of the potential benefit of introducing ASR technology into the Air Traffic Control system is a result of the highly constrained language used by air traffic controllers. Consequently, the information content of the ATC language must be determined, and methods must be designed to process the various levels of knowledge inherently available in ATC communications. The man machine model adopted in this paper demonstrates techniques to utilize syntactic, semantic, and pragmatic information to improve overall recognition accuracy. An intelligent, adaptive voice input parser is presented.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years, the technology and performance of Automated Speech Recognition (ASR) systems has been improving steadily. This has resulted in their successful use in a number of industrial applications. Motivated by this success, a look was taken at the application of ASR to Air Traffic Control, a task whose primary means of communication is verbal. In particular, ASR, and audio playback was incorporated into an Air Traffic Control Simulation task in order to replace blip-drivers, people responsible for manually keying in verbal commands and simulating pilot responses. This was done through the use of a VOTAN VPC2000 ASR continuous speech recognition system which also possessed a digital recording capability. Parsing systems were designed that utilized the syntax of ATC commands, as defined in the controller's handbook, in order to detect and correct recognition errors. As well, techniques whereby the user could correct any recognition errors himself were included. Finally, some desirable features of ASR systems to be used in this environment were formulated based on the experience gained in the ATC simulation task and parser design. These predominantly include continuous speech recognition, a simple training procedure, and an open architecture to allow for the customization of the speech recognition to the particular task at hand required by the parser.

This book was released on 1988 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of air carrier, general aviation, and military traffic has strained this nation's Air Traffic Control (ATC) system. The symptoms of this strain appear as controller fatigue, low controller moral, and the occasional creation of a hazardous situation caused by human error. The current method employed to improve the ATC system has been in the form of increasing its air traffic handling capacity by adding more machinery and manpower. Thus, machines with greater processing power and more humans are coupled into a man machine system which is destined to continually grow. Little has been done in finding new forms of technology to increase the joint efficiency of man and machine. Two relatively new technologies which could create a path towards greater system efficiency are the technologies of voice recognition and artificial intelligence. With greater system efficiency, less controller fatigue and better air safety are expected. Where to apply these technologies, in what form, and how deep these technologies can be integrated into the ATC system are questions which deserve inquiry. This research details a method to answer these questions, develops prototype equipment from which to experiment, and establishes a basis from which other research efforts may be launched. A review of literature indicates that current efforts at applying voice recognition in flight operations are centered around pilot task improvement and special projects such as the space shuttle. While these efforts are certainly important, the controller environment can be just as demanding, stressful, and important. It is within this light that this study is launched.

Download or read book Voice Data Entry in Air Traffic Control written by Donald W. Connolly and published by . This book was released on 1979 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two major experiments and a number of subsidiary pilot studies were conducted to assess the potential operational utility of state-of-the-art word recognition technology in air traffic control applications. Experiment I, employing 12 operators or 'talkers', secured baseline data representing the inherent 'best case' recognition accuracy of the system. Three of the subvocabularies of an operational data entry language were tested exhaustively to a total of over 46,000 spoken words. On the average, across all speakers and all three subvocabularies, only 1 percent of the words spoken were erroneously recognized. Subsequently 'tuning' of the recognition algorithm reduced the error rate to less than 0.4 percent. Experiment II compared the quality and efficiency of the voice system versus the existing keyboard method of entering complete operational messages.

This book was released on 2024-07-24 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural network control has been a research hotspot in academic fields due to the strong ability of computation. One of its wildly applied fields is robotics. In recent years, plenty of researchers have devised different types of dynamic neural network (DNN) to address complex control issues in robotics fields in reality. Redundant manipulators are no doubt indispensable devices in industrial production. There are various works on the redundancy resolution of redundant manipulators in performing a given task with the manipulator model information known. However, it becomes knotty for researchers to precisely control redundant manipulators with unknown model to complete a cyclic-motion generation CMG task, to some extent. It is worthwhile to investigate the data-driven scheme and the corresponding novel dynamic neural network (DNN), which exploits learning and control simultaneously. Therefore, it is of great significance to further research the special control features and solve challenging issues to improve control performance from several perspectives, such as accuracy, robustness, and solving speed.
Download or read book The Routledge Handbook of Translation Interpreting and Crisis written by Christophe Declercq and published by Taylor & Francis. This book was released on 2023-12-22 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook offers a broad-ranging overview of the study of translating and interpreting in conflict and crisis settings and takes the field in new directions. Covering a wide selection of multimodal contexts that build on the fundamentals of translation, interpreting, and their in-between hybrid forms of mediation, the handbook is divided into four parts. The opening part covers perspectives on policy and practices, whether contemporary or historical, and cases truly span the globe, from Peru and Brazil, over Belgium and Sierra Leone, to Australia, Japan, and Hong Kong. International developments require profound considerations about the professionalisation of access to language in times of crises, not least in contexts of humanitarian negotiation or conflict zone interpreting–these form the second part. The subsequent part deals with spheres of community in which language needs are positioned within frames of agency, positionality, and trust, and the challenges that these face. The contributions build on cases where interpreters act as catalysts for translation needs in settings of humanitarian aid and beyond. The final part considers language strategies and solutions in crises. This handbook is the essential guide to translation and interpreting in conflict and crisis settings for advanced students and researchers of translation and interpreting studies and will be of wide interest in peace studies, political science, and beyond.
