Abstract: Techniques for cleaning and calibrating a microphone are discussed herein. For example, a computing device can implement a microphone component to operate a speaker adjacent to a microphone to cause removal of an obstruction (e.g., rain, mud, dirt, dust, snow, ice, animal droppings, etc.) on or near the microphone. The microphone component can also or instead cause the speaker to output a frequency for testing operation of the microphone. By implementing the cleaning and/or calibrating techniques described herein, foreign particle(s) of varying size and type can be dislodged from an area near the microphone to improve performance of the microphone.
