Existing basic research in sound segregation and hearing technology focus on the use of spatial cues to guide auditory attention. Therefore, pitch cues are a potentially rich and unexplored field where significant improvements in speech intelligibility could be found.My hypotheses are as follows:Pitch cues contribute significantly to the degradation of hearing in a multi-talker listening environment performance experienced by patients during ageing and hearing lossRestoring access to these pitch cues will improve speech-in-noise performanceMy proposed DPhil research is an interdisciplinary project aiming to better understand the neural mechanisms underpinning how speakers in multi-speaker environments are understood by patients with hearing loss and explore potential interventions to improve this.I propose the following broad areas of investigation:1. Characterise the relative importance of pitch cues in hearing speech in multi-speaker environments2. Characterise the neurophysiological correlates of speech understanding in multi-speaker environments3. Develop clinically useful diagnostic tests of speech in noise performance4. Explore using targeted pitch cues to improve speech intelligibility in a multi-speaker environmentThe project falls within the remit of healthcare technologies. The overall aim of the project is to determine the importance of pitch cues in multi-speaker environments in order to improve hearing loss interventions. This includes predict performance benefit gained from hearing device use in noisy environments. As such, the research will underpin the optimisation of hearing devices and therefore falls within the EPSRC remit.

现有的声音分离和听力技术基础研究主要集中在利用空间线索来引导听觉注意力。因此，音调线索是一个潜在丰富且未经探索的领域，可以显着改善语音清晰度。我的假设如下：音调线索对老年和听力损失患者在多说话者聆听环境中的听力性能下降有显着影响恢复对这些音调线索的访问将改善噪声中的语音表现我提出的哲学博士研究是一个跨学科项目，旨在更好地理解神经机制 巩固多说话者环境中的说话者如何被听力损失患者理解，并探索改善这一点的潜在干预措施。我提出以下广泛的研究领域：1。描述多说话者环境中听到语音时音调线索的相对重要性2。描述多说话者环境中语音理解的神经生理学相关性3。开发临床上有用的语音噪声性能诊断测试4。探索使用有针对性的音调提示来提高多说话者环境中的语音清晰度该项目属于医疗保健技术的范围。该项目的总体目标是确定多说话者环境中音调提示的重要性，以改善听力损失干预措施。这包括预测在嘈杂环境中使用助听器所获得的性能优势。因此，该研究将支持听力设备的优化，因此属于 EPSRC 的职权范围。
