Abstract
Interfaz de línea telefónica para el desarrollo de aplicaciones vocales interactivas basadas en reconocimiento y síntesis de habla. Tarjeta para ser conectada a un ordenador personal tipo PC, capaz de interactuar con una línea telefónica (de la Red Telefónica Conmutada). Presenta unas características tales que ofrece todas las posibilidades necesarias para el desarrollo y ejecución de aplicaciones vocales interactivas que hagan uso de reconocimiento y síntesis de habla: entrada/salida de audio para tarjetas de reconocimiento de habla, de codificación/compresión de habla y de conversión texto-habla; así como posibilidad de detectar los estados de la línea telefónica, descolgar y colgar automáticamente, detección de tonos multifrecuencia, monitorización de la señal de audio que circula por la línea y reducción de eco. Todas estas funciones pueden ser controladas desde un ordenador personal tipo PC mediante el driver que también se ha desarrollado. La tarjeta consta de: (1) bloque de control,(2) duplexor telefónico con adaptación de niveles y sencillo reductor de eco (retorno de híbrida), (3) detector y decodificador de tonos multifrecuencia, (4) detector de tono de llamada, (5) detector de colgado (polaridad de la línea), (6) adaptadores de señal para auriculares y grabación en magnetófono, y (7) circuitos de activación de relés de línea.Telephone line interface for the development of interactive voice applications based on speech recognition and synthesis. Card to be connected to a PC-type personal computer, capable of interacting with a telephone line (from the Switched Telephone Network). It has such characteristics that it offers all the necessary possibilities for the development and execution of interactive vocal applications that make use of speech recognition and synthesis: audio input / output for speech recognition, speech encoding / compression and conversion cards. text-speech; as well as the possibility of detecting the states of the telephone line, picking up and hanging up automatically, detection of multi-frequency tones, monitoring of the audio signal that circulates on the line and echo reduction. All these functions can be controlled from a PC-type personal computer using the driver that has also been developed. The card consists of: (1) control block, (2) telephone duplexer with level adaptation and simple echo reducer (hybrid return), (3) multifrequency tone detector and decoder, (4) call tone detector , (5) on-hook detector (line polarity), (6) signal adapters for headphones and tape recorder recording, and (7) line relay activation circuits.
