Claims

[Claims for Utility Model Registration] Microphone input means for inputting external audio; speech synthesis means capable of selectively outputting one or more stored audio signals; and audio signals from the microphone input means and a pitch conversion processing means capable of receiving an audio signal from the speech synthesis means, performing a predetermined pitch conversion process on the input audio signal, and outputting the resultant sound signal; and external output means for amplifying and outputting an audio signal to the outside, and configured to convert the pitch of the audio signal from the microphone input means and the audio signal from the audio synthesis means and output the same. Audio output device.
