Synthesized voices for the media and entertainment industry

Disney is one of the main pioneers in the use of voice cloning technology. The media giant has been experimenting with synthesized voices for films, using machine learning algorithms to create realistic-sounding dialog for characters. This technology simplifies ADR and is also used to create new lines for characters without requiring additional recording sessions with actors.

The technology was used in the production of the Disney+ series The Mandalorian, where it helped to create the voice of a younger Luke Skywalker, the character made famous by Mark Hamill, in the show's second season finale. However, rather than casting a younger actor or using advanced de-aging techniques, the show's creators opted to use a combination of visual effects and a synthetic voice created by Respeecher. AI dubbing played a pivotal role in seamlessly matching the original voice of the character.

In the case of The Mandalorian, Respeecher used audio recordings of Mark Hamill from the original Star Wars trilogy to train their algorithm, showcasing the innovative synergy of visual effects and voice AI to create a  and create a synthesized voice that sounded like a younger version of the character. This allowed for the character's dialog to be , with AI voice used to match the original voice of the character.

Respeecher has also been involved in the production of the highly anticipated Disney+ series, Obi-Wan Kenobi, recreating the voice of the most iconic movie villain Darth Vader. During the release of Episode IV: A New Hope, Darth Vader was voiced by actor James Earl Jones. Today however, he is 91 years old. And like everyone else, his voice has changed with age. Lucasfilm decided to restore the menacing timbre of Darth Vader with the help of new AI voice synthesis technologies. Generative AI played a key role in preserving Darth Vader's character, highlighting technology's transformative impact on maintaining authenticity and continuity in the entertainment industry.

Respeecher used archival recordings and a patented AI algorithm to create new dialogs of James Earl Jones’ voice. The company finished working on the project on the day that Russia began its full-scale invasion of its home-country Ukraine.

The benefits of speech synthesis in the film industry

There are several major benefits of synthesized voice in the film industry.

1. AI voice can modify dialog, allowing for changes to be made without requiring additional recording sessions with movie actors. This can reduce production costs and improve the efficiency of the production process.
2. The technology is able to create the voices of characters who are not physically present on set, such as characters who are animated or created using visual effects. This allows for greater flexibility in the production process and helps bring characters to life in new and innovative ways.
3. Speech synthesis can also restore the voices of deceased actors, allowing them to appear in new productions without using archival footage or a different actor to portray the character. It is a valuable tool for filmmakers looking to pay tribute to actors who have passed away, showcasing the profound impact of AI voice synthesis on preserving the legacy of iconic voices in the film industry.

But voice cloning’s greatest benefit may be for indie films, as it allows for greater flexibility in the production process and has proven its ability to significantly reduce costs. By using voice cloning technology, indie animators can create high-quality voice performances without the need for expensive recording sessions or the involvement of numerous voice actors. This can help to level the playing field for indie and big-budget animators by allowing smaller studio animators to create engaging and immersive indie films on a tighter budget.

Moreover, popular voice actors can also benefit from voice cloning technology as it allows them to increase their presence in multiple projects simultaneously, without physically attending recording sessions. Voices, voice actors can give permission for production studios to clone their voices and use them for movie characters.

Voice cloning as a tool for film schools

For film schools, AI and voice cloning technologies introduce a number of creative opportunities, especially the integration of AI dubbing and localization. Students can use AI to analyze and improve their scripts. Voice cloning tools also excel at revealing insights into a dialog's emotional impact or how a scene should be voiced to improve its pacing and emotional resonance. Voice cloning technology can create temporary voiceover tracks for animatics or storyboards, allowing students to experiment with different performances and better understand how their dialog will sound in the final product. Additionally, voice cloning can create temporary placeholder dialog for live-action shoots, allowing students to focus on capturing the visual elements of a scene without worrying about the audio. 

At the Academy of Interactive Education (AIE) in Canberra, film students now have access to cutting-edge technologies used in major productions like The Mandalorian or Thor: Love and Thunder, including AI dubbing and AI voice changer advancements. This non-profit vocational education provider is offering a world-class course using immersive visual effects technologies called StageCraft, an alternative to green screens.

This virtual production technology, increasingly common in high-budget film production, allows filmmakers to create a 3D virtual space similar to a video game setting. Actors perform on a real set with props, while the background is created using a gaming engine and displayed on curved screens. The virtual setting can then be recorded as the background of shots, moving as the camera does, creating the illusion of a real set.

In addition to this, AI is used to capture the movements of actors in a motion-controlled environment. The inclusion of dubbing and localization techniques in film school projects further prepares students for the now globalized nature of the film industry.
