简介:
Overview
This research examines how a foreign accent influences speaker identification, focusing on prosodic features such as voice pitch, duration, and quality. The study aims to understand how these features affect listeners' judgments in voice lineups.
Key Study Components
Area of Science
- Neuroscience
- Psychology
- Forensic Science
Background
- Research on automatic speaker recognition is increasing.
- Prosodic features play a crucial role in speaker identification.
- Forensic scientists often face challenges in interpreting automatic recognition systems.
- Understanding listener judgments can improve forensic practices.
Purpose of Study
- To compare the effects of foreign accents on speaker identification.
- To analyze prosodic-acoustic parameters in voice lineups.
- To enhance the understanding of listener judgments in forensic contexts.
Methods Used
