Description

Research Topic Description, including Problem Statement:

Maintaining intelligibility is fundamental to speech communications. In degraded conditions, microphone capture alone might not be sufficient to sustain intelligibility, prompting the exploratory combined use of alternate sensors.  The research topic posed is whether light detection and ranging (LIDAR) scans, which are enabling detailed 3D models to be made, can be used in-part or in-full to successfully train an automatic speech recognizer (ASR) in degraded conditions. The underlying question is whether machine learning is able to both identify, and then effectively combine potential hidden vocal tract, lip and facial features to maintain intelligibility.

 

Example Approaches:

Three example approaches are listed:

  • Use of LIDAR alone or in combination with a conventional microphonecapture.

  • Use of prior speaker information: enrolment utterances, videos of the personspeaking.

  • Consider use of microphone arrays, and alternative availablesensors.

Note: No Human Subject Research is authorized for the IC Postdoctoral Research Fellowship Program.
