A first approach to Acoustic Characterization of Costa Rican Children’s Speech

As human interaction with computers becomes more pervasive, the value of developing automatic speech recognition, text-to-speech synthesis, and related speech technologies become more important for people of all ages, accents, and conditions. One of the groups that represent bigger challenges is chi...

A medida que la interacción de las personas con las computadoras se hace más extendida, se vuelve más importante el desarrollo de tecnologías para el reconocimiento automático de la voz, la síntesis de voz, así como otras tecnologías relacionadas, considerando a personas de todas las edades, acentos y condiciones. Uno de los grupos humanos que representan desafíos más grandes es el de los niños, debido a las dificultades para grabar suficientes recursos de habla, y la falta de caracterización de su forma de hablar, la cual es particular de cada idioma y acento. Este artículo presenta una primera aproximación para el análisis acústico de niños costarricenses de entre seis y doce años. Estos análisis tienen como objetivo lograr una mejor comprensión de las características del habla producida por este grupo en particular, en términos de propiciar el desarrollo y mejora de los reconocedores automáticos del habla y los sistemas de identificación del hablante. Para este propósito realizamos grabaciones de habla de tres niños, las cuales consistieron en palabras aisladas, y comparamos los resultados con tres adultos en términos de los formantes de las vocales. Los formantes proporcionan información sobre el tracto vocal del hablante, y es un parámetro importante para establecer un primer análisis de estas señales. Los resultados muestran diferencias notables entre los niños y los adultos y pueden brindar información útil para futuros estudios en términos de adaptar y desarrollar las tecnologías del habla para esta población. 2020-03-27 2020-09-25T23:12:53Z 2020-09-25T23:12:53Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/5080 10.18845/tm.v33i5.5080 https://hdl.handle.net/2238/12074 eng https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/5080/4802 application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; 2020: Vol. 33 especial.
