Title:
APPARATUS AND METHOD FOR SPEAKING VERIFICATION FOR VOICE ASSISTANT
Document Type and Number:
WIPO Patent Application WO/2024/005388
Kind Code:
A1
Abstract:
A method includes obtaining audio data and identifying an utterance of a wake word or wake phrase in the audio data. The method also includes generating an embedding vector based on the utterance from the audio data and accessing a set of previously-generated vectors representing previous utterances of the wake word or wake phrase. The method further includes performing clustering on the embedding vector and the set of previously-generated vectors to identify a cluster including the embedding vector, where the identified cluster is associated with a speaker. The method also includes updating a speaker vector associated with the speaker based on the embedding vector and determining, using a speaker verification model, a similarity score between the updated speaker vector and the embedding vector. In addition, the method includes determining, based on the similarity score, whether a speaker providing the utterance matches the speaker associated with the identified cluster.
