voiceprint

1 In New Zealand, the Internal Revenue Department celebrated its 1 millionth voiceprint, leading the revenue minister to boast that his country had “the highest level of voice biometric enrolments per capita in the world”.

2 And should we be worried about the large-scale harvesting of our voiceprints?

3 For companies, the big attraction of voiceprints is to be able to follow consumers as they move from one store or part of a store to another, and between commercial channels.

4 Voiceprint recognition recognizes speakers, and it does not recognize contents of the pronunciation signal of speaker, but the identity of the speaker of the pronunciation signal.

声纹认证不是认证语音信号的文字内容，而是认证发出语音信号的说话人的身份。

5 The voiceprints of suspected fraudsters are kept on a watchlist so they can be identified if they try again pretending to be someone else.

6 The exception covers facial scans and even voiceprints — the kind of technology that Amazon, based in Washington, uses to power Alexa, the virtual assistant that has a microphone in millions of American homes.

7 Banks and other businesses have started using voiceprint checks to verify customers are who they say they are when they phone in.

8 A biometric data collection program appears to have been formalized last year under “Document No. 44,” a regional public security directive to “comprehensively collect three-dimensional portraits, voiceprints, DNA and fingerprints.”

9 "The voiceprint is this underlying kind of timbre of a voice that you can recognize in humans, and this is the first time that has been shown in another vocal learner."

10 Several governments, led by Turkey where the mobile phone company Turkcell has stored voiceprints of 10 million people, have also leapt on the bandwagon.

11 Those companies have helped enter more than 65m voiceprints into corporate and government databases, according to Associated Press interviews with dozens of industry representatives and records requests in the United States, Europe and elsewhere.

12 Five years ago, the technology was mostly about compiling a watchlist of voiceprints associated with known fraudsters and checking this against all incoming calls, says Erica Thomson from Seattle-based security company, Nice Systems.

13 Record a "voiceprint" of this a few times, and afterwards your voice gets checked against this saved sample.

14 The drawback with the system is that banks need to obtain customers' permission before recording voiceprints.

15 It basically verifies a caller’s identity by comparing their voice to the voiceprint the company has stored in its database.

16 So can you ask the taxman to remove your voiceprint?

17 This paper researches identity authentication based on information of voiceprint, and its purpose is pushing the technology become practical.

18 Even identical twins, who share the same DNA, can be told apart from their voiceprints, making the technology reliable enough to be used as evidence in courts of law.

19 Interestingly, the machine learning program only distinguished voiceprints in the former three types of calls.

20 “Creating a voiceprint from the call falls under ‘processing,’” the memo explains.
