How is the long O sound pronounced when followed by を?


For example, 化粧 is read けしょう. When followed by を, how is it pronounced?




There are two things you should try to pay attention to when trying to listen
to or pronouncing a long O.

  1. ### Rhythm

The language is modelled on morae ( _sing._ mora) creating a rhythm. For
example こんにちは is different from こにちわ and a "long O" is either 1,2,3,... morae
long. (Also see [Distinguishing between んな/な, んの/の,
etc](https://japanese.stackexchange.com/q/14213/1628))

  2. ### Pitch

Individual morae can have either a low or a high pitch. A drop or rise in
pitch marks a mora boundary, so this can also help you count.

For example, 化粧を is pronounced [ケショオオ]{LHHLL}. The オオ at the end being twice
as long tells you that the final オ should be を.
