The challenges of audio quality in televisions have been a hot topic for a while now, particularly when it comes to understanding dialogue. As screens have gotten thinner and sleeker, the space for good-sounding built-in speakers has diminished, often compromising sound quality. Recently launched DTS Clear Dialogue offers an innovative solution to this chronic issue. Sven Mevissen, director of streaming and content technologies, delves into the latest technology behind DTS Clear Dialogue, explaining how this AI-powered solution is set to revolutionize the TV viewing experience for both manufacturers and consumers alike.

What is DTS Clear Dialogue?

Sven: DTS Clear Dialogue is an innovative audio technology designed to address a common frustration among TV viewers worldwide: the struggle to understand spoken dialogue. This solution allows viewers to adjust the volume of dialogue independently from other audio elements, effectively putting an end to the all-too-familiar question, “What did they just say?” By improving the clarity and understandability of spoken language on TV, DTS Clear Dialogue enhances the overall viewing experience, allowing viewers to enjoy their favorite content without the need for subtitles or constant volume adjustments.

How does DTS Clear Dialogue work?

Sven: At its core, DTS Clear Dialogue employs advanced AI-based audio processing to transform how we hear dialogue on TV. The technology works through a sophisticated process that first identifies spoken dialogue within any given audio track. Once identified, it then separates this dialogue from background audio elements such as music, sound effects or ambient noise. Following this separation, DTS Clear Dialogue enhances the dialogue for improved clarity. Perhaps most importantly, it gives users the power to personally adjust the dialogue volume to meet their individual needs, creating a truly personalized listening experience. This multi-step approach ensures that viewers can better hear what’s being said, regardless of the content they’re watching or the complexity of the audio mix.

What makes DTS Clear Dialogue different from other solutions?

Sven: DTS Clear Dialogue stands apart from many current solutions in the market due to its focus on personalization and flexibility. Unlike one-size-fits-all approaches, this technology recognizes that every viewer has unique listening preferences and needs. It offers users the ability to adjust dialogue volume to their liking, ensuring optimal clarity for each individual. Moreover, DTS Clear Dialogue is designed with inclusivity in mind, working seamlessly across various languages and content types. Whether you’re watching a Hollywood blockbuster, a local news broadcast, or an international sports event, this technology delivers enhanced dialogue clarity. Additionally, DTS Clear Dialogue offers flexible integration options for TV manufacturers, allowing them to implement the technology in ways that best suit their products and enhance their user interface.

Who can benefit from DTS Clear Dialogue?

Sven: The beauty of DTS Clear Dialogue lies in its universal appeal. This technology is designed to benefit anyone who watches TV, addressing the widespread issue of dialogue intelligibility that affects viewers around the globe. Whether you’re a movie enthusiast trying to catch every nuance of a character’s speech, a sports fan wanting to clearly hear commentators during a noisy game or someone who simply wants to enjoy their favorite shows without straining to understand what’s being said, DTS Clear Dialogue has you covered. It’s particularly beneficial for those with mild hearing difficulties, viewers watching content in a non-native language, or anyone dealing with less-than-ideal viewing conditions, such as background noise at home.

How can TV manufacturers implement DTS Clear Dialogue?

Sven: One of the key strengths of DTS Clear Dialogue is the flexibility it offers to TV manufacturers in terms of implementation. OEMs have several options to integrate this technology in a way that best aligns with their product design and user experience goals. Some may choose to add a dedicated button on the TV remote specifically for dialogue control, providing users with quick and easy access to this feature. Others might opt for a more high-tech approach by implementing voice commands, allowing users to adjust dialogue volume through simple phrases like “increase dialogue volume.” Alternatively, manufacturers could integrate dialogue volume control into the existing TV volume overlay, creating a seamless and intuitive user experience. This flexibility ensures that DTS Clear Dialogue can be implemented in a way that enhances the overall user interface and adds value to the TV’s feature set.

What technology powers DTS Clear Dialogue?

Sven: DTS Clear Dialogue represents the culmination of decades of expertise in audio processing, combined with the latest advancements in AI and machine learning. At its foundation, the technology leverages neural networks capable of running on today’s increasingly powerful TV hardware. These neural networks are trained on an extensive and diverse dataset of audio scenes, enabling the system to accurately identify and process dialogue across a wide range of content types and audio mixes. This AI-driven approach allows DTS Clear Dialogue to perform complex operations in real time, separating and enhancing dialogue with remarkable precision. The result is a technology that not only improves audio clarity but does so with the intelligence to adapt to various audio scenarios, ensuring consistent performance across different types of content.

Is DTS Clear Dialogue only for TVs?

Sven: While the initial focus of DTS Clear Dialogue has been on enhancing the TV viewing experience, the potential applications of this technology extend far beyond. DTS is actively exploring options to offer this solution for other device categories in the near future. This expansion could potentially bring the benefits of clear, adjustable dialogue to a wide range of audio-visual devices, from home theater systems to mobile devices. The versatility of the technology makes it adaptable to various platforms, opening up exciting possibilities for improving audio experiences across multiple entertainment and communication mediums.

How can TV manufacturers get access to DTS Clear Dialogue?

Sven: The DTS Clear Dialogue software development kit (SDK) is fully commercialized and available today. DTS is proactively working with relevant chip partners to ensure broad compatibility and ease of integration. By providing both the necessary software tools and fostering partnerships within the industry, DTS is paving the way for widespread adoption of this technology, ultimately benefiting consumers worldwide.
