Description

Research Topic Description, including Problem Statement:

Aim

Investigate the ability to perform measurably realistic intelligibility listening tests using AI or novel algorithms to increase the efficiencies of tests and improve the accuracy of repeated tests.

Problem Statement

Understanding the impact a device, component, or algorithm has on speech intelligibility is vital when designing or buying a product that captures or processes speech. At present, there are a few standard techniques to test intelligibility including; Speech Transmission Index (STI), Speech Intelligibility Index (SII), and listening tests. STI and SII are limited in their application and do not always accurately reflect the intelligibility impact from a system. The most accurate approach to date involves listening tests. Listening tests are both time and resource intensive, meaning their use is often restricted. In recent years, academia has been developing algorithms to calculate intelligibility metrics, and some of those metrics have been shown to have a one-to-one mapping with listening test data used by the developers. Whether the mappings remain consistent for different scenarios is currently unknown. Before a new algorithm can be adopted, it is important to understand the reliability of the algorithm and understand the circumstances or scenarios in which the algorithm can or cannot be used.

Example Approaches:

The researchers may wish to examine approaches and algorithms from different disciplines including, but not limited to, data science, acoustics, and hearing aid research.

Proposals could consider:

  • Understanding the latest techniques employed in listening tests.
  • Researching a range of approaches and algorithms that exist that relate to speech intelligibility prediction.
  • Understanding capabilities and limitations of approaches that could be used to reduce dependency on listening tests.
  • If mapping between metrics and listening test data, the researchers may want to consider the data set used or perform independent listening tests.
