"Today, technologies that record, repeat and multiply the human voice offer anyone with access to an iPhone the possibility of creating not just new audio recordings, but whole barbershop quartets of audio-doubled, speech-distorted selves. In her 2019 album, PROTO, the musician Holly Herndon pushed this further. She used custom-built AI software to create ethereal cyberchoirs using recordings of her voice and those of her collaborators (among them artist Martine Syms). These digitised phantoms rustle, gasp, arpeggiate and trill in ways no human could, revealing the rich expressive territory that opens up where voice is taken over by software. Rather than threaten the self, such technology expands it. In a noise-polluted age, to fuse your voice with a machine’s may be one way to ensure it reaches people’s ears."
