🗣️🥁 Did early humans use beatboxing? New research suggests that humans might have once used a form of beatboxing, complex overlapping sounds, before the evolution of the consonant-vowel structure we use today.
NewsletterResearchers have long used birdsong as a prime example when studying the complexities of speech. But abased on orangutans attempts to change that and shed some light on how humans acquired the ability to make more than one vocal sound at a time.
With the male apes, the study recorded their “chomps” and “grumble” sounds, which sound like a car revving to start. On a frequency spectrogram, the researchers watched as the chomps, produced by the mouth, registered a high frequency, while the vocalized grumble produced by breath and vocal cords registered a low one. The grumble pattern carries on, repeating quickly, and can indicate annoyance or sometimes pleasure.
