Video content has the power to move, inspire, and connect. But when language barriers stand in its way, that emotional connection can be lost. Now, with advancements in synthetic voice technology, bridging those gaps has become easier and more scalable than ever – unlocking the full potential of your video on a global scale.

In the language services industry, innovation is key to meeting the evolving needs of global business. Leading language service provider, RWS, recognizes the importance of collaboration in driving this innovation. Driven by a culture of continuous improvement, RWS not only invests in its own research and development but also collaborates with technology partners like Voiseed, a pioneer in synthetic voice technology, to push the boundaries of what's possible in localization.

The RWS and Voiseed partnership aims to unlock the video localization needs of global enterprises. Utilizing each other’s strengths and combining human expertise with AI-powered synthetic voices to deliver truly impactful and accessible video content.

The Rise of Synthetic Voices

Synthetic voice technology has come a long way from the early days of robotic, monotone text-to-speech (TTS) systems. Advancements in AI and deep learning have led to the development of incredibly realistic and expressive synthetic voices, capable of capturing the nuances of human speech, including intonation, emotion, and even accents.

These AI-powered voices are already transforming the landscape of video localization. Here are just a few examples of how they are being used:

• eLearning and Training: Synthetic voices are being used to create engaging and accessible eLearning content in various languages, making it easier for businesses to train their global workforce. This not only improves the learning experience for employees but also helps organizations save time and resources by reducing the need for costly voiceover recordings in multiple languages.
• Corporate Communications: Companies are using synthetic voices to create internal training videos, product demos, and marketing materials in multiple languages, ensuring consistent messaging and branding across all markets. This can help improve employee engagement, enhance product understanding, and drive sales in international markets.
• Accessibility: Synthetic voices are being used to generate audio descriptions for video content, making it accessible to visually impaired audiences. This is a crucial step towards creating a more inclusive and accessible media landscape, ensuring that everyone can enjoy and benefit from video content.

However, alongside these advancements come important ethical considerations. As synthetic voices become increasingly realistic, questions arise about voice cloning, ownership of voice data, and the potential for misuse. It's crucial for the industry to proactively address these concerns and ensure responsible development and deployment of this technology.

Problem-Solving with AI Dubbing

This world of synthetic voice technology and its application is diverse and rapidly evolving. Today, we have access to a huge range of AI voices, each – as mentioned above – with its own unique characteristics and applications. This diversity is crucial because it allows for tailored solutions to meet the specific needs of different content creators and industries.

On one hand, we have voices that prioritize clarity and conciseness, making them perfect for eLearning materials, corporate training videos, or technical documentation. Imagine a global company needing to rapidly deploy training materials for a new product launch or a critical safety update. With synthetic voices, they can simultaneously create localized versions of these materials in dozens of languages, ensuring that all employees, regardless of their location, have immediate access to vital information. This not only accelerates the training process but also ensures consistency and accuracy across all markets, leading to a more informed and engaged global workforce.

But the possibilities don't stop there. AI can also be used to create unique and personalized voices that match a brand's identity or target audience. This allows companies to create a consistent brand voice across all their video content, regardless of language or region. A company could create a unique synthetic voice that reflects its brand personality, using this voice for all its video content, from marketing materials to internal training videos.

And finally, we have voices specifically designed for accessibility, providing audio descriptions for visually impaired audiences or enabling individuals with speech impairments to communicate more effectively. These voices play a crucial role in making video content accessible to everyone, regardless of their abilities.

Voiseed CEO, Andrea Ballista said: "AI-powered synthetic voices is an emerging market with a lot of potential for video localization, but they're not a replacement for human expertise. Linguists and localization specialists play a crucial role in ensuring that the translated content is accurate, culturally relevant, and emotionally impactful.

"However, the advancements in synthetic voice technology are truly remarkable. We can now create voices that are virtually indistinguishable from human speech, capturing the subtle nuances of emotion, intonation, and accent. This opens up incredible possibilities for video localization and accessibility, making content more engaging and inclusive for everyone.”

The Importance of Human Expertise

While AI-powered synthetic voices offer incredible potential, the human element remains crucial in video localization. The seamless integration of human expertise and AI technology is essential for achieving truly impactful and authentic results – and this is exactly what RWS is looking to achieve in partnering with Voiseed.

Experienced linguists, voiceover artists, and localization specialists play a vital role in ensuring that video translation is accurate, culturally relevant, and emotionally resonant. These language experts fine-tune the nuances of synthetic voices, ensuring they capture the intended tone and style of the original content or message.

For example, linguists carefully review translated scripts to ensure they accurately reflect the meaning and intent of the original dialogue. They also work with voice actors to ensure the synthetic voices are appropriately adapted to the target culture, considering factors like local pronunciation, dialects, and cultural sensitivities.

Addressing the Challenges of Emotional Dubbing

This human touch is particularly crucial when it comes to the art of emotional dubbing. One of the biggest challenges in video localization is capturing the emotional nuances of the original dialogue in a translated version. This is particularly important in media and entertainment, where emotions play a crucial role in storytelling.

The latest advancements in AI-powered synthetic voices are helping to overcome this challenge by providing more expressive and nuanced voices that can accurately convey a wide range of emotions. However, human expertise is still essential to ensure that the emotional tone and intent of the original dialogue are preserved in the translated version.

Experienced voiceover artists and localization specialists can work closely with AI-powered solutions to fine-tune the emotional delivery of synthetic voices, ensuring they capture the subtle nuances of the original performance. This meticulous approach ensures that the emotional impact of the video is not lost in translation.

Video Localization is Evolving

Video localization is evolving, with AI-powered synthetic voices playing an increasingly important role. As technology continues to evolve, we can expect even more realistic, expressive, and diverse voices to emerge, further enhancing the quality and accessibility of video content worldwide.

The industry is committed to innovation and collaboration, driving continuous improvement and pushing the boundaries of what's possible.

Çetin Amirak, Director, Strategy and Market Insight at RWS said: "We're excited about the potential of AI-powered synthetic voices to transform the way businesses connect with global audiences. By combining cutting-edge technology with human expertise, we can create video content that is not only accessible but also emotionally moving. This is crucial for building trust and true engagement with audiences around the world.”

He added: "However, it's equally crucial to address the ethical considerations surrounding this technology. We must ensure that AI-powered synthetic voices are developed and used responsibly, respecting voice rights, protecting data security, and promoting transparency and accountability."
