Is it true that the べつに when used to mean "nothing particularly" is pronounced differently from when it is used to mean "separately / apart"?


Is it true that the べつに when used to mean "nothing particularly" is pronounced
differently from when it is used to mean "separately / apart" ?

Like am I right to say that these 3 examples belong to the same "sound":

  1. たまに朝飯を抜いたって別に悪いことじゃない。

  2. 「何を考えてるの？」「別に・・・」

  3. べつにいがみあっている敵同士ではあるまいし。

and these other 3 belong to a different "sound":

  1. ニンジンは別にして、彼が食べないものはない。

  2. ソースを別にください。

  3. 別にサービス料を申し受けます。

Also I was wondering whether this sentence _私は別に怪しい者ではありません。_ will belong to
the first category or the second one?




The difference does not appear on `別に`, but appears on the part following it.
In the first usage ('nothing particularly'), the word following `別に` maintains
its own accent nucleus, so the tone lowers at the beginning:

> **Capital = High tone, Lower case = Low tone**  
>  
>  beTSUNI waRUi koto  
>  beTSUNI _[end of accent nucleus]_  
>  beTSUNI iGAMIATte iru

In the second usage ('separately/apart'), `別に` is accently compounded with the
part that follows (the accent nucleus is removed from the following part), so
the high tone sustains into the word following:

> beTSUNI SHITE  
>  beTSUNI KUDASAi  
>  beTSUNI SAABISUryoo o

`私は別に怪しい者ではありません。` belongs to the first category:

> beTSUNI aYASHII MONO de wa

This can be explained by the fact that in the first usage ('nothing
particularly'), `別に` is a sentence modifier, so its bonding with the following
word is weak. In the second usage ('separately/apart'), `別に` is either part of
a predicate or is a verb-phrase modifier, so its bonding with the following
word is strong.
