Doesn't 助けて follow the usual pitch accent rule?


助ける itself is ③, so according to the rule 助けて would become ② as 逃れる 休める etc.
do.

However, I myself find it extremely unnatural to say たすけて in ② rather than ③,
and as I tried it on my iPhone, iOS would read it as ③ (as in 助けてください) or
almost flat as in a bare 助けて.

So my questions are:

  1. _Why_ doesn't that rule apply to 助ける? Are there some other examples on such exceptions?
  2. I can also remember hearing it pronounced as ① somewhere. Does that pronunciation exist?




Since no one takes this, from what I could find:

Textbooks](http://hasegawa.berkeley.edu/Accent/accent.html):

You are observing a most common scenario: moving devoiced accent to the
following mora. Other examples would be any word where accent would otherwise
fall on devoiced syllable. [OJAD](http://www.gavo.t.u-tokyo.ac.jp/ojad/search)
most of the time shows both variants (for instance [危機, 記者,
施設](http://www.gavo.t.u-tokyo.ac.jp/ojad/search/index/sortprefix:accent/narabi1:kata_asc/narabi2:accent_asc/narabi3:mola_asc/yure:visible/curve:invisible/details:invisible/limit:20/word:%E5%8D%B1%E6%A9%9F,%20%E8%A8%98%E8%80%85,%20%E6%96%BD%E8%A8%AD)).

Comments to you post argue that this is what you get when you forcibly try to
accent devoiced syllable.

**Update: Why it makes sense to talk about accent on devoiced mora**

Only the first link above tries to explain this (in a somewhat obscure way),
other take it for granted, yet it doesn't seem to be obvious even to all
native speakers, let alone us mere mortals :).

In some other languages accent (also called stress) is produced by one, any
combination of two, or all three of:

  1. Pitch raise
  2. Sound volume raise
  3. Vowel length increase

Particularly because of (3) long vowels in Japanese are often perceived as
"stressed" by non-natives, and (2)+(3) make it difficult to grasp how devoiced
mora could possibly be accented (though actually it's possible to vary pitch
of a consonant by rising corners of the mouth (i.e. "smiling")).

The first thing to note is that (2) and (3) do not apply to Japanese pitch
accent (as the name suggests). The second thing is that in (1) it's not the
pitch _level_ that matters, but the pitch _change_. Normal speech is not a
mere alteration between high and low pitch, but actually a cascade of pitch
downsteps (audio:
[三人寄れば文殊の知恵](http://assets.languagepod101.com/dictionary/japanese/audiomp3.php?kanji=%E4%B8%89%E4%BA%BA%E5%AF%84%E3%82%8C%E3%81%B0%E6%96%87%E6%AE%8A%E3%81%AE%E7%9F%A5%E6%81%B5&kana=%E3%81%95%E3%82%93%E3%81%AB%E3%82%93%E3%82%88%E3%82%8C%E3%81%B0%E3%82%82%E3%82%93%E3%81%98%E3%82%85%E3%81%AE%E3%81%A1%E3%81%88)).

Contrary to the notation, pitch change occurs not between the morae (there are
no gaps in speech so there's no "between" to begin with), but _within_ the
mora that comes _after_ the accented one. Here are two audio samples from
[OJAD](http://www.gavo.t.u-tokyo.ac.jp/ojad/search/index/sortprefix:accent/narabi1:kata_asc/narabi2:accent_asc/narabi3:mola_asc/yure:visible/curve:invisible/details:invisible/limit:20/word:%E5%8A%A9%E3%81%91%E3%82%8B):
[助ける](http://www.gavo.t.u-tokyo.ac.jp/ojad/sound4/mp3/female/012/1229_1_1_female.mp3?20121005)
and
[助けて](http://www.gavo.t.u-tokyo.ac.jp/ojad/sound4/mp3/female/012/1229_3_1_female.mp3?20121005).
Note how differently け is pronounced: in the first sample the pitch actually
rises during け and falls on る. In the second sample the pitch falls on け.
Hense OJAD shows たすける{LHHL} and たすけて{LHLL} respectively (the low pitch on た is
arguably the result of pronouncing the word in isolation and in real speech
may "inherit" the pitch of the preceding syllable).

Another example is
[記者](http://assets.languagepod101.com/dictionary/japanese/audiomp3.php?kanji=%E8%A8%98%E8%80%85&kana=%E3%81%8D%E3%81%97%E3%82%83):
while second mora is both louder (2) and longer (3) then the first, only pitch
(1) matters, and pitch downstep is quite pronounced (at least to my ear),
hence きしゃ{HLL}.

Finally it's worth remembering that pitch accent of a phrase isn't always a
concatenation of individual accents, the OP's case could even be
たすけてください{LHHHHHHL} (and the accent pattern may stay even when ください is
dropped).

With 一段 verbs with the 中高型 accent, the accent usually shifts to the previous
mora in the te-form:

③[のがれる]{LHHL} → ②[のがれて]{LHLL}

③[そだてる]{LHHL} → ②[そだてて]{LHLL}

③[たずねる]{LHHL} → ②[たずねて]{LHLL}

③[はなれる]{LHHL} → ②[はなれて]{LHLL}

③[ひきいる]{LHHL} → ②[ひきいて]{LHLL}

But as explained in [this
page](https://gist.github.com/k3zi/3f38070efffa38db83cd5745d83b1235):

> 中高型  
>  （一段： accent comes one mora earlier）  
>  ⇨ ◎◎〜◎＼◎て ＬＨ〜Ｈ〜ＬＬ  
>  ⇨ たべ＼る た＼べて  
>  ⇨ み＼る み＼て  
>  ⇨ あつめ＼る あつ＼めて  
>  **（例外： when the accent would fall on a 無声化した母音 (voiceless vowel), it
> doesn't move)**  
>  ⇨ つけ＼る つけ＼て  
>  ⇨ **たすけ＼る たすけ＼て (note that when calling for help this is flat: たすけてー)**  
>  （例外： when the accent would fall on a ん, it moves one more back)  
>  ⇨ ぞんじ＼る ぞ＼んじて

With たすけて, the second mora す is devoiced (since the /u/ sound is between
devoiced consonants /s/ and /k/), which makes it difficult for the accent to
shift to it, hence:

③[たすける]{LHHL} → ③[たすけて]{LHHL}

> Are there some other examples on such exceptions?

I tried but I couldn't find other examples.  
(The page linked above gives ②[つける]{LHL} → ②[つけて]{LHL} as another example, but
I think we usually pronounce its te-form as ①[つけて]{HLL} (付けて、点けて etc.) with a
voiced つ. 漬ける is ⓪[つける]{LHH} → ⓪[つけて]{LHH}.)

I don't think we pronounce it as ①[たすけて]{HLLL} in standard Japanese. (It might
be pronounced that way in some regional dialect.)

I think we often pronounce it like ⓪[たすけて]{LHHH}ー！/ [たすけて]{HHHH}ー！ when crying
for help.
