Abstract

Se provee un aparato para reconstruir una trama que comprende una señal de habla como una trama reconstruida; dicha trama reconstruida está asociada con una o más tramas disponibles, y dicha una o más tramas disponibles es por lo menos una de una o más tramas que preceden a la trama reconstruida y una o más tramas que siguen a la trama reconstruida, en donde la una o más tramas disponibles comprenden uno o más ciclos de tono en forma de uno o más ciclos de tono disponibles. El aparato comprende una unidad de determinación (210) para determinar una diferencia en el número de muestras que indica una diferencia entre un número de muestras de uno de los uno o más ciclos de tono disponibles y un número de muestras de un primer ciclo de tono que debe ser reconstruido. Además, el aparato comprende un reconstructor de tramas (220) para reconstruir la trama reconstruida mediante reconstrucción, en función de la diferencia en el número de muestras y en función de las muestras de dicho uno de los uno o más ciclos de tono disponibles, el primer ciclo de tono a ser reconstruido como un primer ciclo de tono reconstruido. El reconstructor de tramas (220) está configurado para reconstruir la trama reconstruida, de manera tal que la trama reconstruida comprenda por completo o parcialmente el primer ciclo de tono reconstruido, de manera tal que la trama reconstruida comprenda por completo o parcialmente un segundo ciclo de tono reconstruido, y de manera tal que el número de muestras del primer ciclo de tono reconstruido difiera de un número de muestras del segundo ciclo de tono reconstruido.
