项目摘要

Audio Description (AD) for film and television consists of a pre-recorded audio commentary that makes visual content accessible to visually impaired audiences by providing information that clarifies the narrative, such as descriptions on actions, gestures and places. Although, throughout the years, digital technologies have been used to improve the mode of delivery of AD, the notions behind its design have been mostly unchanged despite significant advancements in the field of digital sound production and postproduction. Furthermore, AD is a process separate from the creative production and only considered as an accessibility strategy.The Enhancing Audio Description project investigates how digital audio technologies can transform the design and implementation of AD for film, television and interactive media and as a result, change the ways in which visually impaired audiences experience audio-visual presentations. This research will pioneer novel sound design techniques based on new audio technologies that can be used to enhance AD, providing an audio track that is closer to the artist's vision and that will bridge the gap between sighted and visually impaired audiences. Moreover, the project will enable researchers in the arts and humanities to improve the communication between audio-visual arts and visually impaired audiences and will drive the development of digital technologies and methods that can be used to improve audio-visual experiences for people with sight loss. The project will investigate ways in which AD can be updated through digital technologies to provide both an informative and entertaining experience, while also encouraging the use of the same soundtrack for both visually impaired and sighted audiences. Enhancing Audio Description explores two key methods: The first method investigates recent advancements in surround sound rendering and interactive media systems to create a more spatially accurate soundtrack, which includes an accurate rendition of the positions of characters and objects in space, types of shot, camera movements, camera angles and depth of frame; such a method will reduce the need for descriptions. The second method is the incorporation of first person narration as an alternative to the descriptive voice, to provide an AD that is better suited to the style of the visuals and could prove enjoyable for all audiences. Both methods would require the incorporation of AD to the creative process, transforming it from just an accessibility measure into part of the creative workflows. Whilst both methods are highly applicable to cinematic presentations, the research aims to generalise the approach so that visually impaired audiences can have enhanced soundtracks in a multitude of environments such as in museums, living rooms, or on personalised mobile media devices as well as in a myriad of applications such as film, television, gaming, therapy, training and other audio-visual activities which stimulate the UK digital economy. The proposers will therefore engage with key stakeholders from the film, television, interactive media industries and accessibility services to consider the practicalities of their implementation, including how they fit within current workflows. A significant outcome from the research will be in linking the new technological mechanisms for the enhancement of AD with the overall objective of inclusion in new media services for those with visual impairments.

电影和电视的音频描述 (AD) 包含预先录制的音频解说，通过提供澄清叙述的信息（例如对动作、手势和地点的描述），使视障观众能够理解视觉内容。尽管多年来，数字技术已被用来改进 AD 的交付方式，但尽管数字声音制作和后期制作领域取得了重大进步，但其设计背后的理念基本上没有改变。此外，广告是一个独立于创意制作的过程，仅被视为一种无障碍策略。增强音频描述项目研究数字音频技术如何改变电影、电视和互动媒体广告的设计和实施，从而改变视障观众体验视听演示的方式。这项研究将开创基于新音频技术的新颖声音设计技术，可用于增强AD，提供更接近艺术家视觉的音轨，并弥合视力正常和视障观众之间的差距。此外，该项目将使艺术和人文学科的研究人员能够改善视听艺术与视障观众之间的沟通，并将推动可用于改善视障人士视听体验的数字技术和方法的发展。该项目将研究通过数字技术更新广告的方法，以提供信息丰富且有趣的体验，同时鼓励视障和视力正常的观众使用相同的配乐。《增强音频描述》探索了两种关键方法：第一种方法研究环绕声渲染和交互式媒体系统的最新进展，以创建空间更准确的音轨，其中包括对空间中角色和物体的位置、镜头类型、摄像机运动、摄像机角度和帧深度的准确再现；这种方法将减少对描述的需要。第二种方法是采用第一人称叙述作为描述性声音的替代方案，以提供更适合视觉效果风格并且可以为所有观众带来乐趣的广告。这两种方法都需要将 AD 纳入创意过程，将其从只是一种可访问性措施转变为创意工作流程的一部分。虽然这两种方法都非常适用于电影演示，但该研究旨在推广该方法，以便视障观众可以在博物馆、客厅或个性化移动媒体设备等多种环境中以及电影、电视、游戏、治疗、培训和其他刺激英国数字经济的视听活动等众多应用中获得增强的配乐。因此，提案者将与电影、电视、互动媒体行业和无障碍服务的主要利益相关者合作，考虑其实施的实用性，包括它们如何适应当前的工作流程。该研究的一个重要成果是将增强 AD 的新技术机制与为视力障碍者纳入新媒体服务的总体目标联系起来。
