Laryngophone

"Laryngophones are the very first device for recording the human voice. They allow you to turn vocal sounds into audible sounds. The operating principle is based on the direct transmission of sound and its further transformation into another form; which allows you to obtain a purer sound. There are special methods and technologies for the production of laryngophones , which reduce noise during use."

A laryngophone is a special type of microphone designed to record speech or transmit sounds from a speaker's throat. It can be used to solve a wide variety of tasks, ranging from household (for online conferences or micro-shows) to professional (sports commentators).

Using a laryngophone is quite simple.
