项目摘要
Our ability to communicate successfully with others can be strongly affected by the presence of noise and other voices in the environment, and children and older adults are more greatly affected than young adults in these situations. Even greater disruption is experienced for populations with hearing or language impairments, or even healthy adults who are non-native speakers. Some of the disruption is due to physical masking by interfering sounds (energetic masking EM) but if the disrupting sound can be understood, this also causes further difficulty (informational masking IM). Previous work suggests that informational masking causes relatively more disruption for children and older adults than for young adults but these findings are based on laboratory tests that are far from realistic communication.Although the impact of adverse conditions on speech communication has been the object of studies in different age groups, no study to date has taken a full lifespan view, looking at the relative impact of IM and EM on participants aged from 8 to 85 using a common experimental design. Also, many studies have focused on the impact of EM and IM on speech perception using recorded sentences or words; this ignores the fact that speakers make dynamic adaptations in speech communication to counter the effects of masking. We evaluate the impact of adverse conditions in an interactive task using measures reflecting speech communication efficiency (e.g., task transaction time, rate of dysfluencies). Finally, there is little evidence to date as to whether laboratory-based evaluations reflect the level of difficulty experienced in everyday life. The proposed project will, for the first time, relate evaluations of speech communication difficulties in adverse listening conditions as measured in the laboratory with real-life ratings of difficulty collected in real time over a two week period. It will also test whether primarily informational masking causes greater interference for some age groups (e.g. children, older adults), and if the underlying reasons for the interference differ between children and adults.In Study 1, 120 individuals aged 8 to 85 yrs will be tested in pairs while they carry out a problem-solving task in conditions varying in the degree of informational and energetic masking present. A secondary task will be added to make the task more cognitively demanding, thus reflecting real-life multitasking situations. Baseline measures of hearing, speech perception and cognitive function and a standardised questionnaire of auditory disability (SSQ) will also be collected. In Study 2, the same participants will be asked to report perceived communication difficulty and their listening environment on 6-7 occasions per day during a 2-week period using a smartphone-based app. Data from this study will be related to measures of communication effectiveness and SSQ data collected in Study 1. Finally, in Study 3, spontaneous speech will be collected for a group of 4-7 year olds using the same interactive task to complement measures from our previous corpora (and data for Study 1) and gain a full lifespan set of acoustic descriptors for conversational speech in good listening conditions. This project will lead to a better understanding of how the impact of adverse listening conditions changes across the lifespan, of the relative effects of IM and EM in different age groups, evaluated in realistic communicative conditions, and of the true ecological validity of laboratory-based evaluations. It will also provide normative data for a set of acoustic-phonetic measures across a 4-85 year age range. This benchmark will be of use for practitioners such as speech and language therapists and audiologists who work on aspects of communication with individuals of all ages. Importantly, this research will also contribute to our basic understanding of speech perception and production development across the lifespan.
我们与他人成功沟通的能力会受到环境中噪音和其他声音的强烈影响,在这些情况下,儿童和老年人比年轻人受到的影响更大。对于听力或语言障碍的人群,甚至是非母语的健康成年人来说,干扰更大。一些干扰是由于干扰声音的物理掩蔽(能量掩蔽EM),但如果可以理解干扰声音,这也会导致进一步的困难(信息掩蔽IM)。以前的研究表明,信息掩蔽对儿童和老年人造成的干扰比对年轻人造成的干扰更大,但这些研究结果是基于实验室测试,与现实交流相去甚远。尽管不利条件对言语交流的影响一直是不同年龄组研究的对象,但迄今为止还没有研究采取完整的寿命观点,使用共同的实验设计,观察IM和EM对8至85岁参与者的相对影响。此外,许多研究都集中在EM和IM对言语感知的影响,使用记录的句子或单词,这忽略了一个事实,即说话人在言语交际中进行动态适应,以对抗掩蔽的影响。我们使用反映语音沟通效率的指标(例如,任务事务时间、不流畅率)。最后,到目前为止,几乎没有证据表明实验室评估是否反映了日常生活中的困难程度。拟议的项目将首次将在实验室中测量的不利听力条件下的言语沟通困难的评估与在两周内真实的时间内收集的现实生活中的困难评级联系起来。它还将测试是否主要信息掩蔽会导致更大的干扰,为某些年龄组(如儿童,老年人),如果干扰的根本原因不同的儿童和成人。在研究1中,120个8至85岁的人将被成对测试,而他们在不同程度的信息和精力掩蔽存在的条件下进行解决问题的任务。一个次要的任务将被添加,使任务更具认知要求,从而反映现实生活中的多任务情况。还将收集听力、言语感知和认知功能的基线测量值以及听觉障碍(SSQ)的标准化问卷。在研究2中,同样的参与者将被要求在2周的时间内每天使用基于智能手机的应用程序报告6-7次感知的沟通困难和他们的听力环境。本研究的数据将与研究1中收集的沟通有效性和SSQ数据的测量相关。最后,在研究3中,将收集一组4-7岁奥尔兹的自发语音,使用相同的交互式任务来补充我们以前的语料库(和研究1的数据)的测量,并获得一个完整的生命周期的声学描述符集,用于在良好的听力条件下的会话语音。该项目将导致更好地了解不良听力条件的影响如何在整个生命周期中变化,IM和EM在不同年龄组的相对影响,在现实的沟通条件下进行评估,以及基于实验室的评估的真正生态有效性。它还将为4-85岁年龄范围内的一组声学语音测量提供规范性数据。这个基准将用于实践者,如言语和语言治疗师和听力学家谁的工作方面的沟通与所有年龄段的个人。重要的是,这项研究还将有助于我们对整个生命周期中的言语感知和生产发展的基本理解。
