Deep yes, fake no? Documentary filmmaker uses AI generated quotes

Deep yes, fake no? Documentary filmmaker uses AI generated quotes

[12:02 sun,18.July 2021   by ]    

The question of where authenticity ends and pure storytelling begins in documentary film is a recurring topic of discussion, and not just since it became possible to manipulate images and sounds digitally. However, with increasingly better manipulation possibilities, the discussion is becoming more and more urgent as to which of these means are harmless in documentary storytelling or when a line is crossed.

The documentary Roadrunner: A Film About Anthony Bourdain which has just opened in U.S. theaters and will later be shown on HBO Max, provides a current occasion for this. In it, director Morgan Neville portrays the well-known chef and author who, among other things, undertook culinary journeys for TV until he took his own life in 2018. He does this with the help of all kinds of film and sound recordings from TV, radio, podcasts and audio books, etc., as well as self-conducted interviews - so far, so classic. Bourdain&s typical off-screen voice can often be heard, which is not unusual, so you end up knitting a narrative during editing, with him partly acting as the narrator of his own story.

However, it turns out that they are not always original sounds spoken by Bourdain himself, but among them are also three "audio deepfakes", which were subsequently created especially for the film by an AI, after it was trained with over 10 hours of audio material to be able to deceptively imitate Bourdain&s voice. This was noticed, among others, by a reporter from the New Yorker, who was surprised to hear Bourdain read out an e-mail he had written himself, but the director also speaks openly about this in this interview.

Neville emphasizes that he did not put words into Bourdain&s mouth that he had not written himself, but for dramaturgical reasons he had wished to be able to use them as "original sound" for some quotations. In addition, he had received the green light from Bourdain&s widow and his executor.

So everything is not so bad in this case, one might think. And yet one gets the feeling that the documentary film has -- once again? -- lost its innocence. After all, original sounds were constructed that didn&t exist as such; moreover, a voice automatically adds emotions to a statement that one doesn&t know whether they were contained in the same way in the written passage. In fact, Neville says it wasn&t that easy to decide on a voice pitch, because Bourdain&s voice pitch also changed over the years.

Last but not least, every rule violation stretches the realm of possibility - if it&s OK to have an AI repeat a protagonist&s written sentences, it might not be so far-fetched to tweak the sentence structure a bit, or maybe combine two sentences into one, just as you need for your timing. Perhaps it will soon be possible to link the fake voice with an artificially calculated image, including simulated facial expressions.

The truthfulness of a documentary has always depended to a large extent on the integrity of the person who creates it. But the technical temptations are undoubtedly increasing.
