Double talk detector, method for double talk detection and device incorporating such a detector

摘要: A double talk detector for detecting situations in a device capable of two-way voice communication. The comprises means ( 2 , I) receiving speech signal 3, 5; 30, 50 ), and 82, 83 ) dividing the into subsignals representing specific frequency bands. detection is performed 84, 85, 86 each subsignal, subdecision signals are calculated 87 on basis detection. indicate existence respective subsignals. final decision 89, 90, 91 as DTD signals.
