The Voice-Changing Bowtie is the first gadget created by Professor Agasa for Conan.

Description

By turning the dial on the back Conan is able to imitate all kinds of voices that he hears. When Conan isn't wearing the bowtie, he'll usually store it away in a pocket until he needs it. This gadget is usually used together with the Stun-Gun Wristwatch, prior to receiving it, Conan was shown to knock Kogoro unconscious by kicking an ashtray.

Technical details

The theory behind the Voice-Changing Bowtie is that it works on a frequency modifier system based on patterns from the voice it is to emulate. Voice changers are real technology.

In the real world the Voice-Changing Bowtie has many flaws, such as the frequency response for the size of the speakers in the bowtie wouldn't be able to reproduce frequency of a voice realistically. The frequency modifier, in most cases, wouldn't be able reproduce the subtle but also distinguishable variations of another persons voice. In order to even change the sound in the first place they will need components such as a mic, speaker, processor and powerful batteries to keep it all running. Last but not least the Voice-Changing Bowtie needs to have Conan voice inverted to cancel out his voice completely, otherwise it would be present and noticeable. As this is a fictional drama with many factual references take it with a grain of salt that this is subject to a persons imagination, but these types of technology can and will be possible in the near future if they utilise extremely thin and small magnetic speakers which can accurately reproduce the frequencies accordingly, and the other components reduce drastically in size.

Usage

Under Construction

In most cases, Conan will use the bowtie to simulate Kogoro's voice (and sometimes Sonoko's) to solve a case. However, in some unique situations, Conan used the bowtie to take other people's voices.

Kogoro Mouri

Below is the list of episodes in which Conan mimicked Kogoro's voice. "???" means that the information needs to be verified.
