Abstract: A speech processing system includes one or more analog microphones each arrangeable within a cabin and configured to output a first analog speech signal, one or more digital microphones each arrangeable within the cabin and configured to output a digital speech signal, a digital-to-analog convertor configured to convert the digital speech signal into a second analog speech signal, and a speech signal processer including a delay processer configured to delay at least the first analog speech signal on the basis of a delay time period when the digital-to-analog convertor converts the digital speech signal, which is collected at the same time point as the first analog speech signal, into the second analog speech signal and output the delayed first analog speech signal as a third analog speech signal and configured to perform speech signal processing on the basis of the second analog speech signal and the third analog speech signal.
