Nayeon is an extremely talented and hard-working idol. Although, for the past few months it has been evident that she is having trouble performing on stage due to the recent condition of her voice.

At the beginning of Nayeon's career in TWICE, she had a very full sounding, powerful singing voice. Unfortunately, this is still not the case as a result of having to sing too many high notes and ad-libs in TWICE's songs.

Nayeon tends to strain immensely when it comes to high notes as she belts only in chest voice and puts too much force on her vocal chords. Strain of this proportion can be detrimental to one's singing voice. The results of this are already extremely evident in Nayeon's most recent performances at TWICE's BDZ Arena Tour not too long ago.

Now, Nayeon's singing voice has a thin, sharp, raspy and nasal quality to it and her stamina on stage has lessened as well. Her voice cracks very often and she is has trouble controlling her voice to stay on key and on beat. The most jarring change to her voice is the fact that her vocal range is now significantly limited as compared to her vocal range at the beginning of her career.

A large contributing factor to this issue is the frequency at which TWICE has comebacks every year. This year alone, TWICE has had 6 comebacks (including "Yes or Yes") and 2 tours which is absurd. This would explain why the condition of her voice in the 1 Japanese Album's new tracks is significantly weaker compared to her voice in "Wake Me Up" , which was released just at the beginning of 2018. This is an extreme cause of concern.

It is unacceptable that Nayeon is still expected to perform such extreme vocals with a voice in this state. Her health must be a top priority before anything else but it is very clear that no action is being taken on the company's part, seeing as she is still being allowed to damage her voice even further. Something must be done as she is at risk of permanent vocal damage as her voice is already significantly damaged as is. The only way for her to regain her singing ability is to take adequate vocal rest, undergo vocal rehabilitation, learn proper belting technique to avoid unnecessary strange on her vocal chords. 

If no action is taken then eventually, Nayeon will be ruthlessly berated for her skills as a vocalist as they diminish. This will affect not just her own reputation but also the reputation of JYP Entertainment.
