Humans can detect deepfake speech only 73% of the time, study finds

English and Mandarin speakers found to have the same level of accuracy when detecting artificially generated speech

Humans are able to detect artificially generated speech only 73% of the time, a study has found, with the same levels of accuracy found in English and Mandarin speakers.

Researchers at University College London used a text-to-speech algorithm trained on two publicly available datasets, one in English and the other in Mandarin, to generate 50 deepfake speech samples in each language.
