User identification with voiceprints on online social networks

Abstract:

In one embodiment, a method includes, by one or more computing devices of an online social network, receiving, from a client system of a first user of the online social network, a first audio input from an unknown user, identifying one or more candidate users, wherein each candidate user is a user of the online social network within a threshold degree of separation of a known user, calculating, for each candidate user, a probability score representing a probability that the unknown user is the candidate user, wherein the probability score is based on a comparison of the first audio input to a voiceprint of the candidate user stored by the online social network, wherein each voiceprint comprises audio data for auditory identification of the candidate user, and identifying one of the candidate users as being the unknown user based on the calculated probability scores of the candidate users.
