Servicio de gestión de información remota para las actividades de la vida diaria adaptable a usuario”. Madrid. Estudios de I+D+I, nº 51. [Fecha de publicación: 03/05/2010]. <http://www.imsersomayores.csic.es/documentos/documentos/imserso-estudiosidi-51.pdf> Una iniciativa del IMSERSO y del CSIC © 2003 Portal Mayores http://www.imsersomayores.csic.es Resumen Este proyecto se enmarca dentro de una de las líneas de investigación del Centro de Estudios Tecnológicos para Personas con Dependencia (CETDP – UPC) de la Universidad Politécnica de Cataluña que se dedica a desarrollar soluciones tecnológicas para mejorar la calidad de vida de las personas con discapacidad. Se pretende aprovechar el gran avance que representan las nuevas tecnologías de identificación con radiofrecuencia (RFID), para su aplicación como sistema de apoyo a personas con déficit de distinta índole. En principio estaba pensado para personas con discapacidad visual, pero su uso es fácilmente extensible a personas con problemas de comprensión y memoria, o cualquier tipo de déficit cognitivo. La idea consiste en ofrecer la posibilidad de reconocer electrónicamente los objetos de la vida diaria, y que un sistema pueda presentar la información asociada mediante un canal verbal. Consta de un terminal portátil equipado con un trasmisor de corto alcance. Cuando el usuario acerca este terminal a un objeto o viceversa, lo identifica y ofrece información complementaria mediante un mensaje oral. Para ello los objetos han de estar debidamente etiquetados por el fabricante. Para facilitar la interacción (interfaz), se ha desarrollado un sistema de acceso a la memoria de todos los elementos de lectura de etiquetas inteligentes, ya sea de modo inalámbrico mediante Wifi, o por cable, mediante Ethernet, a un servidor remoto para obtener la información de una etiqueta concreta y el producto al que va asociado. Consecuentemente se ha desarrollado un sistema de etiquetaje inteligente de todos los productos. La tendencia del mercado es que se imponga un sistema de etiquetaje global. Este sistema en un futuro será una forma más de identificación como ahora puedan ser un número de serie o un código de barras. Con un servicio remoto se ofrece la posibilidad de que el fabricante (en el caso de medicamentos) o terceras personas autorizadas puedan modificar la información útil para el usuario acerca del producto etiquetado. Otro de los objetivos del proyecto es el de desarrollar un sistema de etiquetado único y homogéneo, con un único diseño, flexible y adaptable, partiendo de la identificación cuidadosa de los usuarios. Aunque se ha confeccionado un modelo provisional de usuario, queda pendiente una futura línea de investigación de corte etnográfico, en la que se tenga en cuenta la heterogeneidad sociodemográfica del colectivo de usuarios.

    Part 2: RHYTHM – DURATION AND TIMING Część 2: RYTM – ILOCZAS I WZORCE CZASOWE From research to application: creating and applying models of British RP English rhythm and intonation Od badań do aplikacji: tworzenie i zastosowanie modeli rytmu i intonacji języka angielskiego brytyjskiego David R. Hill Department of Computer Science The University of Calgary, Alberta, Canada [email protected] ABSTRACT Wiktor Jassem’s contributions and suggestions for further work have been an essential influence on my own work. In 1977, Wiktor agreed to come to my Human-Computer Interaction Laboratory at the University of Calgary to collaborate on problems asso- ciated with British English rhythm and intonation in computer speech synthesis from text. The cooperation resulted in innovative models which were used in implementing the world’s first completely functional and still operational real-time system for arti- culatory speech synthesis by rule from plain text. The package includes the software tools needed for developing the databases required for synthesising other languages, as well as providing stimuli for psychophysical experiments in phonetics and phonology.

  • Half a Century in Phonetics and Speech Research
    Fonetik 2000, Swedish phonetics meeting in Skövde, May 24-26, 2000 (Expanded version, internal TMH report) Half a century in phonetics and speech research Gunnar Fant Department of Speech, Music and Hearing, KTH, Stockholm, 10044 Abstract This is a brief outlook of experiences during more than 50 years in phonetics and speech research. I will have something to say about my own scientific carrier, the growth of our department at KTH, and I will end up with an overview of research objectives in phonetics and a summary of my present activities. Introduction As you are all aware of, phonetics and speech research are highly interrelated and integrated in many branches of humanities and technology. In Sweden by tradition, phonetics and linguistics have had a strong position and speech technology is well developed and internationally respected. This is indeed an exciting field of growing importance which still keeps me busy. What have we been up to during half a century? Where do we stand today and how do we look ahead? I am not attempting a deep, thorough study, my presentation will in part be anecdotal, but I hope that it will add to the perspective, supplementing the brief account presented in Fant (1998) The early period 1945-1966 KTH and Ericsson 1945-1949 I graduated from the department of Telegraphy and Telephony of the KTH in May 1945. My supervisor, professor Torbern Laurent, a specialist in transmission line theory and electrical filters had an open mind for interdisciplinary studies. My thesis was concerned with theoretical matters of relations between speech intelligibility and reduction of overall system bandwidth, incorporating the effects of different types of hearing loss.

The computer system used for this purpose is called a speech computer or speech synthesizer, and can be implemented in software or hardware. The text-to-speech system (TTS) converts the usual text of language into speech; other systems display symbolic linguistic representations, such as phonetic transcriptions in speech. Synthesized speech can be created by concatenating fragments of recorded speech that are stored in the database. Systems vary in size of stored speech blocks; The system that stores phones or diphones provides the greatest range of outputs, but may not have clarity. For specific domain use, storing whole words or suggestions allows for high-quality output. In addition, the synthesizer may include a vocal tract model and other characteristics of the human voice to create a fully synthetic voice output. The quality of the speech synthesizer is judged by its similarity to the human voice and its ability to be understood clearly. The clear text to speech program allows people with visual impairments or reading disabilities to listen to written words on their home computer. Many computer operating systems have included speech synthesizers since the early 1990s.

  • Towards Expressive Speech Synthesis in English on a Robotic Platform
    PAGE 130 Towards Expressive Speech Synthesis in English on a Robotic Platform Sigrid Roehling, Bruce MacDonald, Catherine Watson Department of Electrical and Computer Engineering University of Auckland, New Zealand s.roehling, b.macdonald, [email protected] Abstract Affect influences speech, not only in the words we choose, but in the way we say them. This pa- per reviews the research on vocal correlates in the expression of affect and examines the ability of currently available major text-to-speech (TTS) systems to synthesize expressive speech for an emotional robot guide. Speech features discussed include pitch, duration, loudness, spectral structure, and voice quality. TTS systems are examined as to their ability to control the fea- tures needed for synthesizing expressive speech: pitch, duration, loudness, and voice quality. The OpenMARY system is recommended since it provides the highest amount of control over speech production as well as the ability to work with a sophisticated intonation model. Open- MARY is being actively developed, is supported on our current Linux platform, and provides timing information for talking heads such as our current robot face. 1. Introduction explicitly stated otherwise the research is concerned with the English language. Affect influences speech, not only in the words we choose, but in the way we say them. These vocal nonverbal cues are important in human speech as they communicate 2.1.

Hill Department of Computer Science, University of Calgary, AB, Canada © 1979, 2015 David R. Hill Summary Speech offers humans a means of spontaneous, convenient and effective communication for which neither preparation nor tools are required, and which may be adapted to suit the developing requirements of a communication situation. Although machines lack the feedback, based on understanding and shared experience that is essential to this form of communication in general, speech is so fundamental to the psychol- ogy of the human, and offers such a range of practical advantages, that it is profitable to develop and apply means of speech communication with machines under constraints that allow the provision of adequate dialog and feedback. The paper details the advantages of speech com- munication and outlines speech production and perception in terms relevant to understanding the rest of the paper. The hierarchy/heterar- chy of processes involved in both automatic speech understanding and the machine generation of speech is examined from a variety of points of view and the current capabilities in terms of viable applications are noted.

O conteúdo do presente relatório é de única responsabilidade dos autores. A Systematic Literature Review on Awareness of Others in Accessible Collaborative RIAs Leonelo D. A. Almeida, M. Cecília C. Baranauskas Institute of Computing, University of Campinas (UNICAMP) Albert Einstein Av., 1251, 13083-970, Campinas-SP, Brazil {leonelo.almeida, cecilia}@ic.unicamp.br Abstract. The more robust and dynamic aspects of Web 2.0 applications (also named Rich Internet Applications, RIAs) stimulate the participation and collaboration among people while interacting with such shared interaction spaces. An evident consequence (e.g. Facebook, Instagran, and Twitter) is the increasing influence of RIAs on other media channels as TV and newspapers. However, the current state-of-art of Web 2.0 does not provide equitative opportunities of interaction for people. Accessibility in RIAs is still a challenging objective. Also, for aspects as awareness of others on RIAs that provided collaboration features the development of accessible mechanisms is not restricted to semantic markup but it also involves data structures, politeness, load of data, and other characteristics. This technical report presents a Systematic Literature Review process designed for investigating the aspect of awareness of others in accessible collaborative RIAs; it also reports included and excluded studies and the data collected from the reviewed studies. Keywords: Web 2.0, Accessibility, Systematic Literature Review.
