A wearable translation device attachable to a body of a user includes a microphone device that obtains a voice of a first language from the user and generates an audio signal of the first language, and a control circuit that obtains an audio signal of a second language converted from the audio signal of the first language. The wearable translation device further includes an audio processing circuit that executes a predetermined process on the audio signal of the second language, and a speaker device that outputs the processed audio signal of the second language as a voice. Further, when detection is made that a vocal part of the user is located above the speaker device, the audio processing circuit moves a sound image of the speaker device from a position of the speaker device toward a position of the vocal part of the user according to the detection.
