Only a few seconds of sampling is enough to create an AI copy of a person’s voice, and researchers are unsure why they are so intelligible.
Voice clones, which can recreate a human’s speech using only a few seconds of recorded speech, are more intelligible in noisy environments, research finds. AIP
WASHINGTON, April 21, 2026 — Synthetic voices are increasingly a part of our lives, from digital assistants like Siri and Alexa to automated telemarketers and answering machines. With the expansion of generative AI, a new type of synthetic voice has been developed: voice clones, which can recreate a facsimile of a person’s voice from only a few seconds of recorded speech.
