PROBLEM TO BE SOLVED: To provide a voice transmission device and a voice transmission method which allow for localization of a sound image at an appropriate position, without relying upon a headphone or an earphone to be used and without being heard around, when reproducing a high resolution, high sampling sound containing ultrasonic components.SOLUTION: A voice transmission device 100 for making a voice containing ultrasonic components to be heard by means of a headphone 10 includes at least one high frequency speaker 104 for outputting a voice from which the non-audible high frequency band is extracted, and a DSP 105 for convolving a signal being outputted to the headphone 10 by using the transfer function of an acoustic path between a listener and the high frequency speaker 104. |
