5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Overview and general recommendation:

In this study, the difference between the arousal and valence of emotions felt toward Hangul phonemes was explored according to consonant and vowel through comparison between Korean and Chinese women. This is an interesting study and the authors have collected a unique dataset using rigorous methodology. The design of two groups of participants from different language backgrounds makes the experiment reasonable for the purpose. I believe the authors conducted the experiment carefully in line with the strict procedure. Overall the paper is generally well written and structured. Thus, the current study is a topic of relevance and general interest to the reader of the journal.

Nonetheless, I found some of the description of the paper to be irrelevant while the descriptions of some points were inaccurate. Given this, I recommend that a minor revision is warranted. I explain my concern and raise my questions in more detail below.

Minor comments:

1. In the abstract and other part of your paper, I suggest to use consonant, instead of articulation or articulation methods to avoid confusion. In the field of Phonetics Phonology, the term ‘articulation’ refers to the configuration which produces the sounds of speech while both consonant and vowel belong to phoneme category.

2. Page 2, line 4 of the countdown. “contain meaning (eg, /ka/, /nu/, /si/)”, punctuation missing?

3. Page 2, line 3 of the countdown. “impact on However,”, typo?

4. Page 4, line 8-9 of the countdown. From a linguistic point of view, it is more appropriate to categorized them with vowel, consonant and tone). Articulation methods seem strange. You are suggested not to use this term as ‘consonant’ is more accurate, in accordance with vowel and other segmental or supra-segmental units. For the same consideration, ‘tone’ is proposed to replace to ‘frequencies’.

5. Page 15, line 11. “see. In fact,”, typo?

6. Page 15, line 5-7 of the countdown. What do you mean by “The syllable consonants in Korean are 7 of ㅂ/p/, ㄷ/t/, ㄱ/k/, ㅁ/m/, ㄴ/n/, ㅇ/ ŋ, ㄹ/l, while Chinese is only 2 of /-n/ and / ŋ/.”? Please check and confirm. I guess you are mentioning the coda types differences between Korean and Chinese?

Reviewer #2: This paper conducts an experiment exploring the difference of the arousal and valence of emotions felt toward Hangul phonemes between Korean and Chinese women. The conclusions are insightful, however, there are some questions remaining unsolved.

Firstly, the articulation of consonants consists of the place of articulation and the method of articulation. This paper only considers the method of articulation, so the author should clarify why they don’t take the effect of the place of consonants into account.

Secondly, this paper simply using nationality as the factor of cultural differences, however, the Chinese participants in this paper are all living in Korea, the length of time living in Korea may affect the result.

Thirdly, Chinese has at least seven dialects including Cantonese, Min, Hakka, etc. The southern dialects are quite different from Mandarin. In this paper, the authors do not consider the different dialectal backgrounds of the participants or at least not clarify this point. For example, most southern Chinese dialects have -m, -n, -ŋ, -p, -t, -k coda. So, in the discussion section, the discussions on the differences of Korean and Chinese is only true for Mandarin Chinese.

Fourthly, since the experiment was conducted online, the outside environments are not the same for all participants. This will somehow affect the result since the researchers can’t clearly see how the participants finish the experiments.

Are there any data of participants are invalid and how the distinguish?

In sum, the experiment done in this paper has shed some lights on the difference of emotions felt toward Hangul phonemes between Korean and Chinese women. The authors should control the experiment environments, and consider more about the dialectal backgrounds of participants, so as to draw a rigorous conclusion.

Typo errors:

p10: “Cultural differences can affect the perception of morphemes with meaning (eg, happiness, anger, fear), but the smallest sound unit that does not contain meaning (eg, /ka/, /nu/, /si/) It is easy to expect that cultural differences will not have an impact on However”

Response to the Reviewer #1

1. In the abstract and other part of your paper, I suggest to use consonant, instead of articulation or articulation methods to avoid confusion. In the field of Phonetics Phonology, the term ‘articulation’ refers to the configuration which produces the sounds of speech while both consonant and vowel belong to phoneme category.

A) As you pointed out, we use the word “consonant” instead of articulation or articulation methods.

2. Page 2, line 4 of the countdown. “contain meaning (eg, /ka/, /nu/, /si/)”, punctuation missing?

A) We corrected the missing punctuation.

3. 3. Page 2, line 3 of the countdown. “impact on However,”, typo?

A) We corrected the wrong upper case letter(However) to lower case letter(however).

4. Page 4, line 8-9 of the countdown. From a linguistic point of view, it is more appropriate to categorized them with vowel, consonant and tone). Articulation methods seem strange. You are suggested not to use this term as ‘consonant’ is more accurate, in accordance with vowel and other segmental or supra-segmental units. For the same consideration, ‘tone’ is proposed to replace to ‘frequencies’.

A) As you pointed out, we modified “consonant and tone” to replace to “articulation and frequencies”.

5. Page 15, line 11. “see. In fact,”, typo?

A) We deleted the typo error.

6. Page 15, line 5-7 of the countdown. What do you mean by “The syllable consonants in Korean are 7 of ㅂ/p/, ㄷ/t/, ㄱ/k/, ㅁ/m/, ㄴ/n/, ㅇ/ ŋ, ㄹ/l, while Chinese is only 2 of /-n/ and / ŋ/.”? Please check and confirm. I guess you are mentioning the coda types differences between Korean and Chinese?

A) We appreciate for pointing out the error. We modified the sentence to convey the exact content.

Response to the Reviewer #2

1. the articulation of consonants consists of the place of articulation and the method of articulation. This paper only considers the method of articulation, so the author should clarify why they don’t take the effect of the place of consonants into account.

A) Because of the classification of consonants varies depending on the language, we considered only plain consonant, aspirated consonant, and voiced consonant which is a common consonant in many languages and known to give a similar emotional impression in this study. The concepts that were not fully considered in this study were mentioned as limitations of the study.

2. this paper simply using nationality as the factor of cultural differences, however, the Chinese participants in this paper are all living in Korea, the length of time living in Korea may affect the result.

A) This study was conducted on Chinese people who came to live in Korea after entering a Korean university. They are Chinese who have been introduced to Korean culture since they became adults, it is assumed that they have a unique cultural characteristic acquired in the process of growing up even if they have become familiar with Korean culture. However, as you pointed out, all the levels of Korean cultural experience of each participant had not controlled. But this study is the first study to compare the difference in perception between arousal and valence values for Korean language, so we discussed it in terms of limitations so that it can be fully considered in future studies.

3. Chinese has at least seven dialects including Cantonese, Min, Hakka, etc. The southern dialects are quite different from Mandarin. In this paper, the authors do not consider the different dialectal backgrounds of the participants or at least not clarify this point. For example, most southern Chinese dialects have -m, -n, -ŋ, -p, -t, -k coda. So, in the discussion section, the discussions on the differences of Korean and Chinese is only true for Mandarin Chinese.

A) In this study, only Chinese who use Mandarin were required to response to the questionnaire when distributing the questionnaire. This was not specified in the paper, so the relevant content was written reflecting what you pointed out.

4. since the experiment was conducted online, the outside environments are not the same for all participants. This will somehow affect the result since the researchers can’t clearly see how the participants finish the experiments.
Are there any data of participants are invalid and how the distinguish? The experiment done in this paper has shed some lights on the difference of emotions felt toward Hangul phonemes between Korean and Chinese women. The authors should control the experiment environments, and consider more about the dialectal backgrounds of participants, so as to draw a rigorous conclusion.


A) Although the experiment was conducted online, the environment of all participants was not controlled equally, but we emphasized the notice of the main points before participating in the experiment as follows: 1) Set the time to run the experiment for 1 hour (do not interrupt this experiment in the middle), 2) the surrounding environment is set so that it is not affected by external stimuli (e.g., noise), 3) recommend using earphones and check the computer volume of device in advance.

Since this study was intended to measure the emotional response to auditory stimuli presented, it was assumed that the participants’ basic emotional state would have a more significant influence, although the surrounding environmental factors were important at the time of the experiment. Accordingly, the emotional state of each participant was measured in advance, and as a result, it was confirmed that there was no difference in the emotional state of the participants.

5. Typo errors:
p10: “Cultural differences can affect the perception of morphemes with meaning (eg, happiness, anger, fear), but the smallest sound unit that does not contain meaning (eg, /ka/, /nu/, /si/) It is easy to expect that cultural differences will not have an impact on However”

A) We corrected as “Cultural differences can affect the perception of morphemes with meaning (eg, happiness, anger, fear), but the smallest sound unit that does not contain meaning (eg, /ka/, /nu/, /si/). It is easy to expect that cultural differences will not have an impact on however,”

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #2: 1. There is no voiced consonant in Mandarin Chinese, the result find in the paper shows that ‘line 216-218 Korean reported higher arousal than Chinese in lenis and aspirated consonant, whereas there was no distinct difference between nationalities in voiced consonant’. So, the phonetic system (inventories) of Mandarin may affect the reaction of Chinese women in this experiment, since lenis and voiced consonants are only phonetic variants, but not phoneme in Mandarin. I think this point is more pivotal than the differences between end sounds in Korean and Chinese as the author mention. But in the discussion part, the authors do not mention the lack of voiced consonant in Mandarin.

2. Although the authors mention three limitations at last, we should be aware that all these limitations make the present paper less convincing. I suggest the authors to conduct the same experiment on male participants and see whether the result is the same with the women’.

Below is one confusing sentence and the authors need to double check.

(1) p3 line 58, For example, it is assumed that the word for dog in thousands of languages will use consonants and vowels to symbolize large entities, and consonants and vowels to symbolize relatively small entities for ants.

Some typos:

(1) p4 line 80, According to the existing claim that all sounds have acoustic characteristics such as ‘rough or soft’, strong or weak’… [only one ’ ]

(2) p8 line 157, measures ''trait anxiety'', it is better to use ‘’ in English instead of “”.

Revision 2

We appreciate your sincere comments.

1. There is no voiced consonant in Mandarin Chinese, the result find in the paper shows that ‘line 216-218 Korean reported higher arousal than Chinese in lenis and aspirated consonant, whereas there was no distinct difference between nationalities in voiced consonant’. So, the phonetic system (inventories) of Mandarin may affect the reaction of Chinese women in this experiment, since lenis and voiced consonants are only phonetic variants, but not phoneme in Mandarin. I think this point is more pivotal than the differences between end sounds in Korean and Chinese as the author mention. But in the discussion part, the authors do not mention the lack of voiced consonant in Mandarin.

A) We added discussion as followed: Koreans showed higher arousal than Chinese in lenis and aspirated consonants, while there was no clear difference between nationalities in voiced consonants. In general, Mandarin Chinese does not use voiced and voiceless sounds as discriminator as in Korean, so how well Chinese and Korean distinguish between voiced and aspirated sounds does not seem to affect the valence of audible sounds. However, the response values to the voiced consonants collected in this study tended to be somewhat lower in both Koreans and Chinese compared to lenis and aspirated consonants. In other words, it is estimated that the sound accompanying the vocal cords like voiced consonants lowered the arousal level, while it played a role in activating valence level.

2. Although the authors mention three limitations at last, we should be aware that all these limitations make the present paper less convincing. I suggest the authors to conduct the same experiment on male participants and see whether the result is the same with the women’.

A) We appreciate for your sincere opinion. In this study, only one gender was selected that could be considered similar in response level or pattern, assuming that there may be a difference in response according to experience depending on the emotional state. Therefore, we tried to match the homogeneity of the emotional state or level within the group as much as possible. However, as we also pointed out in our paper, we will conduct further studies on men with the same experiment, since it is assumed that gender differences may exist according to cultures. We are currently preparing for a specific experiment and will implement it soon.

3. Below is one confusing sentence and the authors need to double check.
(1) p3 line 58, For example, it is assumed that the word for dog in thousands of languages will use consonants and vowels to symbolize large entities, and consonants and vowels to symbolize relatively small entities for ants.

A) We modified the sentence as: For example, in thousands of languages, the word ‘dog’ tends to use consonants and vowels with sounds that can represent relatively large entities, while consonants and vowels with smaller sounds can be used to symbolize relatively small entities, such as ‘ant’.

4. Some typos:
(1) p4 line 80, According to the existing claim that all sounds have acoustic characteristics such as ‘rough or soft’, strong or weak’… [only one ’ ]
(2) p8 line 157, measures ''trait anxiety'', it is better to use ‘’ in English instead of “”.

A) We corrected all the typos you found.

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: In this study, the difference between the arousal and valence of emotions felt toward Hangul phonemes was explored according to consonant and vowel through comparison between Korean and Chinese women. This is an interesting study and the authors have collected a unique dataset using rigorous methodology. The design of two groups of participants from different language backgrounds makes the experiment reasonable for the purpose. I believe the authors conducted the experiment carefully in line with the strict procedure. Overall the paper is generally well written and structured. Thus, the current study is a topic of relevance and general interest to the reader of the journal.

Reviewer #2: The authors have already answered my questions and they have corrected all the typos. So I have no any further questions.
