Abstract
Un aparato para controlar el procedamiento de voz en una disposicion telefonica digital utilizando la determinacion de estaco de un cancelador deeco. Un cancelador de eco es utilizado para evaluar en cual de los cinco estados de habla están comprometidos dos oradores en una conversaciontelefonica. Esta informacion de determinacion de estado es utilizada para controlar una funcion de detector de tonos, una funcion de supresor de ruido,una funcion de ecualizador adaptivo, una funcion de silenciamiento de transmision, y una funcion de codificacion de vocodificador (vocoder) dentro deun vocodificador (vocoder). Durante el estado de habla donde el orador del terminal lejano está activo y el orador del terminalcercano está inactivo, elcancelador de eco provee una senal la cual deshabilita las estimaciones del ruido de fondo que son realizadas en el supresor de ruido y el codificador devocodificador (vocoder). La misma senal es utilizada para deshabillitar la funcion de silenciamiento de transmision durante el estado de habla. También sepropone un método para controlar el procesamiento de voz en una disposicion telefonica digital mediante dicho aparato, no son que comprende básicamente lasetapas de general una senal de estado mediante un cancelador de eco y controlar un elemento de procesamiento digital utilizando dicha senal.An apparatus for controlling voice processing in a digital telephone arrangement using the staking of an echo canceller. An echo canceller is used to assess which of the five speech states two speakers are engaged in in a telephone conversation. This status determination information is used to control a tone detector function, a noise suppressor function, an adaptive equalizer function, a transmission mute function, and a vocoder encoding function within a vocoder. (vocoder). During the speech state where the far end speaker is active and the near end speaker is inactive, the echo canceller provides a signal which disables the background noise estimates that are made in the noise suppressor and the decoder (vocoder). ). The same signal is used to disable the transmission mute function during the speech state. A method for controlling voice processing in a digital telephone arrangement by said apparatus is also proposed, other than basically comprising the general stages of a status signal by an echo canceller and controlling a digital processing element using said signal.
