WebMar 11, 2024 · In biometric parlance, we use the terms False Acceptance Rate (FAR) and False Rejection Rate (FRR) to describe the percentage chance that an incorrect user will be falsely accepted or a correct user will be falsely rejected, respectively. WebFalse rejection occurs when the system rejects a valid speaker, and false acceptance when the system accepts an imposter speaker. Both types of error are a function of the decision threshold used in the template matching and nearest neighbor methods. Choosing a high threshold of acceptance will result in high FRR (low FAR).
