4月 pitch accent


NHK日本語発音アクセント辞典 lists 4月 as either しがつガ{LHHL} or しがつガ{LHHH}, but is しがつ{HLL}
also said?

Examples: [1](https://youtu.be/S8l5r2i8bhw?t=233),
[2](https://youtu.be/KqiSp0ZFCaE?t=3353),
[3](https://youtu.be/FMi0b62yd0g?t=282), [4](https://youtu.be/w-Dk147jJ_M)




Yes, even though NHK prescribes that にがつが{LHHL}, しがつが{LHHL}, ごがつが{HLLL},
くがつが{HLLL} are correct accent, にがつ{HLL}, しがつ{HLL} are also heard, that
effectively regularize all 3-mora month names in 頭高型.

In my observation, this type of accentuation is mostly heard when the speaker
refers to a specific date, presumably intending to make the number sound more
salient. It is less likely to appear when you talk about, say,
[『四月は君の嘘』](https://ja.wikipedia.org/wiki/%E5%9B%9B%E6%9C%88%E3%81%AF%E5%90%9B%E3%81%AE%E5%98%98).
