How do you spell the sound make when your tired?

There isn't a single, universally recognized spelling for the sound someone makes when they're tired. Here are some possibilities depending on the specific sound:

For a deep sigh:

* Sigh

* Whew

* Ugh

For a yawn:

* Yawn

* Aaah

* Haa

For a tired groan:

* Groan

* Mmm

* Ugh

For a sleepy mumble:

* Mmm

* Mmph

* Mmm-hmm

Ultimately, the best way to represent the sound would be to describe it using words like "tired sigh," "sleepy groan," or "deep yawn." You could also use onomatopoeia, which is the use of words that imitate sounds.
