1. A voice input system comprising:
a first voice input apparatus; and
a second voice input apparatus capable of communicating with the first voice input apparatus,
wherein each of the first voice input apparatus and the second voice input apparatus comprising;
a first microphone configured to collect a voice at a first position outside an ear canal of a speaker, and output a first input voice signal based on the collected voice;
a second microphone configured to collect a voice at a second position outside the ear canal of the speaker and closer to a mouth of the speaker than the first position, and output a second input voice signal based on the collected voice;
a third microphone configured to collect a voice inside the ear canal of the speaker, and output a third input voice signal based on the collected voice;
a controller configured to detect a sound pressure of the first input voice signal, set a first reflection degree indicating a reflection degree of the second input voice signal and a second reflection degree indicating a reflection degree of the third input voice signal according to the detected sound pressure, and generate an output voice signal including at least one of the second input voice signal and the third input voice signal based on the first reflection degree and the second reflection degree; and
a communication unit configured to transmit the output voice signal to an outside,
wherein the controller of the first voice input apparatus determines whether a magnitude of the sound pressure of the first input voice signal in the second voice input apparatus is larger than a magnitude of the sound pressure of the first input voice signal in the first voice input apparatus, and sets the output voice signal to be transmitted to the outside, based on a determination result.
