A corrigendum on
An acoustic study of vocal expression in two genres of Yoruba oral poetry
by Akinbo, S. K., Samuel, O., Alaga, I. B., and Akingbade, O. (2022). Front. Commun. 7:1029400. doi: 10.3389/fcomm.2022.1029400
In the published article, there were a few text errors. These have been outlined below.
A correction has been made to the Abstract. This sentence previously stated:
“For this study, we conducted an experiment, involving the vocalization of an original poem in speech mode, Ìjálá and Èsá.”
The corrected sentence appears below:
“For this study, we conducted an experiment, involving the vocalization of an original poem in speech mode, Ìjálá and Ẹ̀sà.”
A correction has been made to Methodology, Stimuli, participant and procedure, paragraph 4. The sentences previously stated:
“To make each vibrato vocalization at least 3 s long, each of the vibrato vowel were tripled by itself. It is from the tripled form that we extracted vibrato rate.”
The corrected sentences appear below:
“To make each vibrato vocalization at least 3 s long, each of the vibrato vowels was sextupled by itself. It is from the sextupled form that we extracted vibrato rate.”
A correction has been made to Discussion and conclusion, paragraph 2. The sentence previously stated:
“…that Ìjálá and Ẹ̀sa are typically performed to a large audience in an open space…”
The corrected sentence appears below:
“…that Ìjálá and Ẹ̀sà are typically performed to a large audience in an open space…”
A correction has been made to Discussion and conclusion, paragraph 7. The sentence previously stated:
“…vocal expression such as pitch raising distinguishes genres of Yorùbá oral poetry from speech.”
The corrected sentence appears below:
“…vocal expressions, such as pitch raising, vowel epenthesis and lengthening, distinguish Ìjálá, Ẹ̀sà and speech.”
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
