摘要:

助听器被期望提高听力障碍者的言语清晰度。一个适当的放大配件调谐为听众的听力残疾是至关重要的良好的性能。大多数规定性的配件的发展是基于主观听力实验中收集的数据,这通常是昂贵和耗时的。在本文中,我们探索了一种替代方法,通过引入助听器语音处理框架,找到最佳的拟合,其中拟合是优化的,在自动化的方式使用基于HASPI生理听觉模型的可懂度目标函数。该框架是完全可微的,因此可以采用反向传播算法进行有效的数据驱动优化。我们最初的客观实验显示了无噪声语音放大的良好效果,其中自动优化的处理器优于公认的助听器处方之一。

英文摘要:

Hearing aids are expected to improve speech intelligibility for listeners with hearing impairment. An appropriate amplification fitting tuned for the listener's hearing disability is critical for good performance. The developments of most prescriptive fittings are based on data collected in subjective listening experiments, which are usually expensive and time-consuming. In this paper, we explore an alternative approach to finding the optimal fitting by introducing a hearing aid speech processing framework, in which the fitting is optimised in an automated way using an intelligibility objective function based on the HASPI physiological auditory model. The framework is fully differentiable, thus can employ the back-propagation algorithm for efficient, data-driven optimisation. Our initial objective experiments show promising results for noise-free speech amplification, where the automatically optimised processors outperform one of the well recognised hearing aid prescriptions.
