The Rise of the Robo-Voices (wsj.com) 54

Posted by msmash from the shape-of-things-to-come dept.
The next time you see a movie or TV show that was dubbed from a foreign language, the voices you hear may not belong to actors who rerecorded dialogue in a sound booth. In fact, they may not belong to actors at all. From a report: Highly sophisticated digital voice manufacturing is coming, and entertainment executives say it could bring a revolution in sound as industry-changing as computer graphics were for visuals. New companies are using artificial intelligence to create humanlike voices from samples of a living actor's voice -- models that not only can sound like specific performers, but can speak any language, cry, scream, laugh, even talk with their mouths full. At the same time, companies are refining the visual technology so actors look like they are really speaking.

As streaming services export American fare globally and foreign markets send their hits to the U.S., dubbing is a bigger business than ever. But the uses of synthetic voices extend well beyond localizing foreign films. AI models can provide youthful voices for aging actors. The technology can resurrect audio from celebrities who have died or lost the ability to speak. And it can tweak dialogue in postproduction without the need for actors. All the tinkering raises thorny ethical questions. Where is the line between creating an engrossing screen experience and fabricating an effect that leaves audiences feeling duped?

The technology is set to hit a new target in the coming months, when foreign-language dubbed versions of the 2019 indie horror movie "Every Time I Die" are released in South America. Those versions mark one of the first times entire dubbed movies use computerized voice clones based on the voices of the original English-speaking cast. So when the film comes out abroad, audiences will hear the original actors "speaking" Spanish or Portuguese. Deepdub created the replicas based on 5-minute recordings of each actor speaking English.

    Isn't that the whole point of filmmaking unless it is a documentary? How are -computer generated voices different than visual effects of deaging an actor in a scene? What's the next thorny question, "Where is the line between based on a true story and fiction drawn?"

        I'm skeptical that reading subtitles makes a person a better or worse reader.

        The big advantage of subtitles is the quality of the story. There is no way to translate without changing the story, but with subtitles and rudimentary knowledge of the spoken language you can understand the original a lot better. If it

          For movies with original voices in English I can say for sure from experience that German sub-titles are usually much further from a perfect translation than are dubbed German soundtracks. For sub-titles, they often shorten/simplify what is said a lot, and this does not preserve the true meaning of the original sentences.

          • All you're saying is that the people writing one translation did a better job than the people writing the other one. It has nothing to do with anything.

            And Germans understand English well enough that they'll get a better idea of what was intended by having both. You can't translate all of what is said in conversational English to German. To get the same effect you have change what was said. That changes the subtleties, and it changes the personality of the character. It's just garbage. It tells a similar st

  • Where is the line between creating an engrossing screen experience and fabricating an effect that leaves audiences feeling duped?

    Why would anyone feel duped? Ideally, a viewer should never see an actor as their real self, but as the character they are acting. If they are seeing the actor more than the character, the actor has totally failed.

    The purpose of using an existing actor's voice would be to use a voice that has been recognized as high quality. I doubt they'll do it for too many years because they'll eventually figure out how to make better than real life voices that don't require paying someone royalties - which is important

      Well, that's interesting.

      Train a GAN to prefer Morgan Freeman, then have it listen to millions of synthetic voice variants and find the ones it prefers over Morgan Freeman.

      Yes, this avoids the IP issues entirely.

      • Probably easier than my thought. I'd look for what it is about the human auditory pathway that causes us to prefer Morgan Freeman and work toward a mathematical function to describe degree of vocal satisfaction. I'm pretty sure they already know most of it. It's likely highly tied to what we find pleasing in music which has garnered a lot of research by mathematical folks. Once you describe that function, you'd just find the voice that maximizes it.

        Of course, I could go back to your solution and train the n

    It's actually happening faster than I'd thought it would, but it really looks like we're going to have completely realistic computer-generated movies 'soon' (where soon may still be a few decades).

    With a large enough catalog of voices and faces, pre-rigged characters to skin, motions mapped and physics applied, there's no reason you couldn't add a flowchart for script generation and massive selections of possible appropriate lines tailored for the flow of the plot and the base characters... and have your PC make you a movie on demand, just for you.

    I thought voice would take longer than video, but it looks like they're going to cross the finish line at the same time.

        Speaking of Star Trek, I wouldn't mind at all seeing 10 more seasons of TNG and Voyager. The new one just doesn't do it for me. I do like it, but not nearly as much as TNG and Voyager. DS9 is kinda soapy, but still better than the last Star Trek. Even "Enterprise" is better than the last Star Trek. It's because I like a good storyline, not constant laser fire and FX without any depth or substance to the story.

      • The 4th season of Star Trek was actually done as was the 5th... fan made, but pretty good quality as Star Trek Continues.

        Some of the writing can make you cringe (so can some of the acting) but it's in line with the original show which wasn't exactly subtle when trying to make a point. The sets, the costumes, and the effects are very much appropriate for TOS, though likely upgraded for higher resolution viewing.
