Способ синхронного кодирования периода основного тона речевых сигналов включает операции подачи входного речевого сигнала, обработки входного речевого сигнала для определения характеристик его качества, включая коэффициенты кодирования с линейным предсказанием и огласованность, и описаний возбуждения, соответствующего входным речевым сигналам, в частотной области, когда входные речевые сигналы содержат огласованную речь, для получения функции возбуждения. Способ также включает операции описания входных речевых сигналов во временной области, когда входные речевые сигналы содержат неогласованную речь, для получения соответствующей функции возбуждения и кодирования функции возбуждения для получения цифрового выходного сигнала, представляющего входной речевой сигнал.A method for synchronously encoding a pitch period of speech signals includes inputting an input speech signal, processing an input speech signal to determine its quality characteristics, including linear prediction coding coefficients and consistency, and excitation descriptions corresponding to input speech signals in the frequency domain when the input speech The signals contain voiced speech to get the excitation function. The method also includes operations of describing the input speech signals in the time domain, when the input speech signals contain incoherent speech, to obtain the corresponding excitation function and to encode the excitation function to obtain a digital output signal representing the input speech signal.
