When it comes to biometrics, the first comes to our mind may be fingerprints and palmprints. Most of us usually unlock a system or log in our account with something we know, a password or perhaps an answer to a challenge questions. However, biometrics make it possible to do it based on something we are, our unique biologic features.
Voiceprint technology, also called speaker recognition technology, is one of the biometrics. In the speaker recognition technology, features of speaker’s voice can be extracted to uniquely present the person.
For fingerprint technology, the data is collected through a finger print scanner, while in speaker recognition, only a microphone is needed. Hence, it is much cheaper. The other advantage is that it can be done remotely, either through smartphone or normal phone or any equipment with a microphone in it.
However, unlike fingerprint technology, people seems to be less familiar with speaker recognition technology and they tend to think that it is not that reliable. In the link below about Voice Trust, the engineer said they already have the speaker recognition technology which can recognize a speaker no matter which language he says, that means it is text-independent. In addition, the system can recognize you either you use smartphone or high quality phones, whether you use good quality network or even when you catch a cold, the system is robust enough to recognize the speaker
What do you think about speaker recognition technology? Do you trust it? Imagine a voiceprint lock is option of your phone’s screen lock type, will you choose it or you still prefer to use password or fingerprint?
