#Deepfake text to speech free verification
Fortunately, voice verification tools already exist. The good news is, even if humans have trouble separating real from fake, computers don’t have the same limitations. But a poor-quality phone call recording or a conversation captured on a handheld device in a noisy parking garage will be much harder to evaluate. If someone is speaking directly into a studio-quality microphone, you’ll be able to listen closely. The clearer the sound quality, the easier it is to notice signs of an audio deepfake. For shorter clips, though, you might not notice it’s synthetic-especially if you have no reason to question its legitimacy. The longer a sound clip is, the more likely you are to notice there’s something amiss.
“Then, we can compare that knowing the customer uses an AT&T phone in Atlanta.” “Our acoustic signature allows us to determine that a call is actually coming from a Skype phone in Nigeria because of the sound characteristics,” said Pindrop CEO, Vijay Balasubramaniyan. In 2019 alone, Pindrop claims to have analyzed 1.2 billion voice interactions and prevented about $470 million in fraud attempts.īefore voice cloning, fraudsters tried a number of other techniques. The simplest was just calling from elsewhere with personal info about the mark. Security company Pindrop tries to stop bank fraud by verifying if a caller is who he or she claims to be from the audio. “It can be used by anyone who’s got moderate proficiency in coding.” Security Pros Have Seen All This BeforeĬriminals have tried to steal money by phone long before voice cloning was possible, and security experts have always been on call to detect and prevent it. “A lot of the progress in the space has come through collaborative work in places like GitHub, using open-source implementations of previously published academic papers,” Ajder said. The music and background sounds help disguise some of the obvious robotic glitchiness, but even in this imperfect state, the potential is obvious. It’s spot on.Įlsewhere on YouTube, you can hear a flock of ex-Presidents, including Obama, Clinton, and Reagan, rapping NWA. YouTube channel Vocal Synthesis features well-known people saying things they never said, like George W.
You don’t have to go far to find surprisingly convincing audio fakes, either. claimed it was tricked by an audio deepfake phone call into wiring money to criminals. After all, there have already been cases in the news of people being duped by voice clones. This technology, along with nuclear power, nanotech, 3D printing, and CRISPR, is simultaneously thrilling and terrifying.

In the past, systems needed dozens or even hundreds of hours of audio. One of the biggest innovations in voice cloning has been the overall reduction in how much raw data is needed to create a voice. “Instead of a computer seeing a picture of a horse and saying ‘this is a horse,’ my model could now make a horse into a zebra,” said Aylett. “So, the explosion in speech synthesis now is thanks to the academic work from computer vision.” Ebert then asked the company to create a replacement voice, which they did by processing a large library of voice recordings. “Ebert saw that and thought, ‘well, if they could copy Bush’s voice, they should be able to copy mine,'” said Matthew Aylett, CereProc’s chief scientific officer. CereProc had published a web page that allowed people to type messages that would then be spoken in the voice of former President George Bush. In 2008, synthetic voice company, CereProc, gave late film critic, Roger Ebert, his voice back after cancer took it away. However, modern voice cloning promises something even better. Of course, voice replacement is nothing new in medicine-Stephen Hawking famously used a robotic synthesized voice after losing his own in 1985. Voice-cloning companies are also excited about medical applications. Here, a voice that sounds authentically human and responds personally and contextually without human input is what’s important. There are also more traditional uses in advertising, and tech and customer support.
