Juli\\xe1n Duque is a Lead Developer Advocate at Salesforce and Heroku. He\'s joined by Alex Serdiuk, the CEO of Respeecher. Respeecher has created AI software which works within the speech-to-speech domain: it takes one voice and makes it sound exactly like another. Alex rejects the premise that all deep fakes--that is, pictures and videos generated by AI--are inherently evil. He considers tools like CGI and Photoshop to fall within the realm of synthesized media, which helps artists create content. He positions Respeecher within that same mileu.

Respeecher has been working with Hollywood studios for some time. It removes pressure from actors who are unable to rerecord lines. It\'s also been used in situations where actors need to sound much younger, a visual-audio process called de-aging. In the future, applications of speech-to-speech work could also be used in museums, to provide a new dimension of history for audiences.

Of course, Alex recognizes that the main issue with deep fakes is not their existence, but their inability to be detected. To solve this problem, Respeecher watermarks its audio, to generate inaudible metadata which can nonetheless be analyzed to show whether a particular recording was faked. He also believes that more people need to be educated that synthesized media exists. Something one sees or hears might not be real, because technology is getting more and more advanced. We should all be mindful about the content we consume.
