To date, two major types of acoustic stimuli have been used to evoke frequency-following responses (FFRs) – either by using a consonant-vowel or by using a vowel with intonation, but not both. The goals of this study were to (1) determine the feasibility of recording FFRs by forging a CV and intonation into one acoustic stimulus, and (2) examine the characteristics of such responses. Twelve Chinese adults (8 females, 4 males, age = 25.58 ± 4.23 years old) were recruited. FFRs were elicited by using the consonant-vowel /da/ combined with a rising intonation pattern (fundamental frequencies 85-93 Hz) for a total of 8000 sweeps from each participant. Six objective indices (Consonant Amplitude, Consonant Latency, Consonant Slope, Frequency Error, Tracking Accuracy and Pitch Strength) were derived from all recordings. Results demonstrated that it was feasible to record the consonant, vowel and intonation responses simultaneously. Results also demonstrated distinctive FFR trends with increasing number of sweeps for the consonant, vowel and intonation responses. Taken together, these findings may have important implications for basic research and clinical applications.To date, two major types of acoustic stimuli have been used to evoke frequency-following responses (FFRs) – either by using a consonant-vowel or by using a vowel with intonation, but not both.
