Abstract

Как часть системы и способа передачи сигнального тона по сети с пакетной коммутацией данных (или другой сети передачи данных) блок кодирования звука может включать блок (20) кодирования речи и блок (10) искажения тона. Блок искажения тона может искажать один или больше компонентов сигнального тона в звуковом сигнале, и блок (20) кодирования речи может кодировать речь и искаженный сигнальный тон в звуковом сигнале. Сигнал управления может быть передан в генератор (60) тона для воспроизведения искаженного тона.Отчет о международном поиске был опубликован 2003.12.31.
