This is the sound of me brushing my teeth using a generic white and purple toothbrush from Kroger and Sensodyne Pronamel toothpaste. The audio features me brushing the front and back of my teeth.
I recorded my friend Zoe using her thumb and forefinger to pluck against her cheek, mouth open. The outcome sound was very similar to water droplets by a slightly turned off faucet.
Warbling is to create shrill, quavering sounds with the mouth. My close friend Diana likes to use this sound as her mating call at parties, so I asked her to imitate the sound while recording.
