Guarding against scams（3）
SUMMARY
身分詐称詐欺はある共通要素によってさらに巧妙化しつつあると、連邦政府当局は注意を呼びかけています。その共通点はクローン音声を使っていることです。詐欺師はAIを使って、あなたの家族の声をまねることができます。詐欺師に必要なのは、オンラインに投稿されたコンテンツから簡単に入手できる、その家族の声の短い音声クリップと、音声クローニングプログラムだけなのです。

VIGNETTE
Frank Saloom: And now federal officials are warning us that these schemes are becoming more sophisticated with one common element ― cloned voices.
Ide Kyohei: Yes, it's pretty scary. Scammers can use AI to mimic the voice of your loved ones. All they need is a short audio clip of the actual person's voice, which they can easily get from content posted online, and a voice cloning programm. So, when the scammer calls you, they could sound exactly like a loved one. A reasonably good clone can be created with under a minute of audio. And some claim that even a few seconds will do.
Lidia Grace: Voice cloning scams have been a threat for a while now. But what really concerns me is how easily accessible and user friendly AI has become. Almost anyone with a computer can now clone someone's voice thanks to the widespread availability of powerful AI technology.
Jane Rosenberg: It's important to be cautious when scammers ask you to make payments or send money in ways that make it difficult to trace and recover your funds. For instance, if they tell you to wire money, use cryptocurrency, or buy give cards and provide them with the card numbers and PINs, those are usually red flags.
Ide Kyohei: What can we do to protect ourselves from these scams?
Jane Rosenberg: Well, if you receive a call from some one claiming to be from your bank, my advice would be to say that the phone connection is poor and that you will call them back.
