Design and development of a speech synthesis software for colombian spanish applied to communication through mobile devices

In several scenarios of everyday life, there is a need to communicate orally with other people. However, various technological solutions such as mobile phones cannot be used in places such as meetings, classrooms, or conference rooms without disrupting the activities of people around the speaker. This research develops a tool that enables people to establish a conversation in a public place without disrupting the surrounding environment. To this end, a speech synthesizer is implemented on a personal computer connected to a cell phone, which allows one to establish a mobile call without using the human voice. The speech synthesizer uses the diphone concatenation technique and is developed specifically for the Spanish from Colombia. A mathematical description of the synthesizer shows the decomposition of the synthesizer into various mutually independent processes. Several user-acceptance and quality tests of the obtained signal were performed to evaluate the performance of the tool. The results show a high signal to noise ratio of generated signals and a high intelligibility of the tool

Sin embargo, diversas soluciones tecnológicas como la telefonía móvil no pueden ser utilizadas en lugares como reuniones, salones de clase, conferencias, entre otras, sin interrumpir las actividades de las personas alrededor del hablante. Este trabajo de investigación desarrolla una herramienta que permite entablar una conversación de voz en un recinto público sin interrumpir las actividades del medio circundante. Para ello se implementa un sintetizador de voz en una computadora personal comunicada de forma alámbrica con un teléfono móvil, lo cual permite establecer una llamada sin utilizar la voz humana. El sintetizador de voz utiliza la técnica de concatenación de difonemas y es desarrollado específicamente para el idioma español de Colombia. Una descripción matemática del sintetizador muestra su descomposición en diversos procesos independientes entre sí. Se realizaron diversas pruebas de aceptación de usuarios y de calidad de la señal obtenida para evaluar el desempeño de la herramienta. Los resultados muestran una alta relación señal a ruido de las señales generadas y una alta inteligibilidad de la herramient
