Voice correction device

Abstract

The present invention provides an audio correction device and an audio correction method that can correct the output sound to be suitable for the environment in which the audio equipment is installed. [Solution] A smartphone acting as an audio correction device and a separately configured in-vehicle unit are able to communicate with each other, and the smartphone is further capable of wirelessly communicating with a server. The smartphone acquires characteristic information of the smartphone's microphone 15 from the server using the vehicle receiving unit 11, acquires information regarding the orientation of the smartphone using the G sensor 18, the calculation unit 13 generates white noise sound using the white noise generation unit 14 and outputs the white noise sound to the in-vehicle unit, the recording unit 16 records the white noise sound using the microphone 15 and measures it, and the calculation unit 13 generates correction information based on the characteristic information of the microphone 15, the information regarding the orientation of the smartphone, and the measurement results.
