Are haiku typically "padded" when read aloud?


I was once told that haiku should be "padded" so that instead of 5/7/5, they
fit an 8/8/8 meter:

> ■■■■■□□□ ← wait for 3 beats after this line  
>  ■■■■■■■□ ← wait for 1 beat after this line  
>  ■■■■■□□□ ← wait for 3 beats after this line

If I recall correctly, the explanation was that Japanese favors rhythms in
groups of 4 or 8 beats (morae). I don't actually know if haiku are read this
way, though--it's just something I was told once.

Are haiku actually read aloud with these pauses? Or is this something my
friend made up?




Yes, I think you'd read it as:  

> ■■■■■□□□  
>  ■■■■■■■□  
>  ■■■■■□□□  
>

for 5/7/5 like [かたつむり・・・](http://vocaroo.com/i/s1YJ9B4eoecl) where the middle
line can be split into 4+3(e.g.: トウキョウ・ナゴヤ).  
And you'd read it as:  

> ■■■■■□□□  
>  □■■■■■■■  
>  ■■■■■□□□  
>

for 5/7/5 like [静かさや・・・](http://vocaroo.com/i/s07exKb7uVUZ) where the middle
line sounds better when split into 3+4(e.g.: カワズ・トビコム).  

And you'd probably read it as:  

> ■■■■■□□□  
>  ■■■■■■■■  
>  ■■■■■□□□  
>

for 5/8/5, like [8/5/8/5/8/5...
