Abstract:
A method of authenticating a speech signal in a first device comprises receiving a speech signal, and performing a live speech detection process to determine whether the received signal represents live speech. The live speech detection process generates a live speech detection output. A certificate is formed by encrypting at least the live speech detection output. The received signal, and the certificate, are transmitted to a separate second device.
