Is it-- "I'm sorry," she sighed.
OR "I'm sorry." She sighed. I was told you can't sigh dialogue, yet I see it in some books.
"Hi, there," he smiled.
Or "Hi there." He smiled. Same thing here--you can't smile dialogue.
"I'm sorry," she said sighing.
"I'm sorry," she said, letting out a sigh.
She sighed. "I'm sorry."
Sighing, she said, "I'm sorry."
She let out a sigh. "I'm sorry."
Similarly-
"Hi, there." He greeted him with a smile.
He smiled. "Hi, there."
"Hi, there," he said, a smile creasing his face.
You don't need to always use said/answered etc to terminate a dialogue.
You could do something like that also.
He turned to her--a smile creasing his face. "Hi, there."
or you simply could just write: "Hi, there." (under certain circumstance only.)
But under no circumstance use sighed/smiled in the same way as said/answered/stated/returned etc.
