Generally, in English emphasis is provided by simply putting more spoken emphasis on a word–either by a change in volume or tone. English also has the emphatic tenses which in certain circumstances can show emphasis to a listener or reader: I did not see you there. I did go, honestly!

Please see Emphatic Tenses in the Grammar Slammer glossary or https://www.englishplus.com/grammar/00000328.htm.

Inversion can also used to express emphasis, often with conditional tenses, sometimes with the emphatic tense, sometimes with auxiliary verbs such as can or will, sometimes with the perfect tense, and sometimes with the verb to be.

Wow! Could he sing! [conditional]
Did we have fun last night! [emphatic, not a question…]
Whew! Can he play football! [emphatic, not a question]
Will she be surprised! [not a question]
Have we got a deal for you! [perfect tense]
Was she happy to see you! [verb to be]

Though most of these are constructed like questions, they are written with exclamation points. They also are spoken quite differently. A question rises in tone. An emphatic statement moves slower and goes down in tone.

I hope this helps.
