  1. 1. How do voiceprints age?

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Maya Konstantinovna Nachesa; [2023]
    Nyckelord :Voiceprint; Speaker Emotion Recognition; Age; Speaker Verification;

    Sammanfattning : Voiceprints, like fingerprints, are a biometric. Where fingerprints record a person's unique pattern on their finger, voiceprints record what a person's voice "sounds like", abstracting away from what the person said. They have been used in speaker recognition, including verification and identification. LÄS MER
