Problem:<\/strong><\/h2>\n

Speaker recognition: is the process of automatically recognizing who is speaking by using the speaker-specific information included in speech waves to verify identities being claimed by people accessing systems; that is, it enables access control of various services by voice.<\/p>\n

Speaker verification (also called speaker authentication) contrasts with identification.<\/p>\n

Speaker recognition:<\/strong><\/p>\n

2-stage speaker recognition: Enroll and verify<\/strong><\/p>\n

Before we can verify a speaker, we need the user to enroll his voice:<\/p>\n

Speak:<\/p>\n

“Hello” 3 times<\/p>\n

and random strings 2 times<\/p>\n

Store the averaged embedding vector on database use for speaker recognition.<\/p>\n
