Effects of Natural Versus Synthetic Consonant and Vowel Stimuli on Cortical Auditory-Evoked Potential.
Background and objectives: Natural and synthetic speech signals effectively stimulate cortical auditory evoked potential (CAEP). This study aimed to select the speech materials for CAEP and identify CAEP waveforms according to gender of speaker (GS) and gender of listener (GL).
Subjects and methods: Two experiments including a comparison of natural and synthetic stimuli and CAEP measurement were performed of 21 young announcers and 40 young adults. Plosive /g/ and /b/ and aspirated plosive /k/ and /p/ were combined to /a/. Six bisyllables-/ga/-/ka/, /ga/-/ba/, /ga/-/pa/, /ka/-/ba/, /ka/-/pa/, and /ba/-/pa/-were formulated as tentative forwarding and backwarding orders. In the natural and synthetic stimulation mode (SM) according to GS, /ka/ and /pa/ were selected through the first experiment used for CAEP measurement.
Results: The correction rate differences were largest (74%) at /ka/-/ pa/ and /pa/-/ka/; thus, they were selected as stimulation materals for CAEP measurement. The SM showed shorter latency with P2 and N1-P2 with natural stimulation and N2 with synthetic stimulation. The P2 amplitude was larger with natural stimulation. The SD showed significantly larger amplitude for P2 and N1-P2 with /pa/. The GS showed shorter latency for P2, N2, and N1-P2 and larger amplitude for N2 with female speakers. The GL showed shorter latency for N2 and N1-P2 and larger amplitude for N2 with female listeners.
Conclusions: Although several variables showed significance for N2, P2, and N1-P2, P1 and N1 did not show any significance for any variables. N2 and P2 of CAEP seemed affected by endogenous factors.
期刊介绍：
Journal of Audiology and Otology (JAO) (formerly known as Korean Journal of Audiology) aims to publish the most advanced findings for all aspects of the auditory and vestibular system and diseases of the ear using state-of-the-art techniques and analyses. The journal covers recent trends related to the topics of audiology, otology, and neurotology conducted by professionals, with the goal of providing better possible treatment to people of all ages, from infants to the elderly, who suffer from auditory and/or vestibular disorders and thus, improving their quality of life. This journal encourages the submission of review papers about current professional issues, research papers presenting a scientific base and clinical application, and case papers with unique reports or clinical trials. We also invite letters to the editor and papers related to the manufacture and distribution of medical devices. This journal provides integrated views from otologists, audiologists, and other healthcare practitioners, offering readers high quality scientific and clinical information. This peer-reviewed and open access journal has been the official journal of the Korean Audiological Society since 1997 and of both the Korean Audiological Society and the Korean Otological Society since 2017. It is published in English four times a year in January, April, July, and October.
