Some words to simplify or make the word "said" sound better:
"Said" : A general word that people used alot, though it still has uses and its not all bad,
Ex: i said to my mom, that iwanted ice cream <i think Direct object is getting to me anyways>
"Spoke/Speak" : though if in past/present tense, use Spoke as for Speak better to use it too man it aint alone probably used as a present tense but how am i suppose to know lol
Spoke Ex: i spoke to my teacher about my grades
Speak Ex: i speak greatly about my friends
"Cooed" : basically speaking in a soft voice, yeah thats about it but dont over use it, it gets ugly
Ex: This trip is amazing, she cooed
"Murmur" : a soft indistinctive sound that either a person or a group made
Ex: He murmured a soft tune for his mother
"Mumbled" : a quiet indistinctive utterance
Ex: She replied in a mumble, She mumbled softly to my ears

Next, using of words with more formality
(No context much added in this sorry for the utterly confusion)
"As for"
Ex: As for what happened i do not know
"As which"
Ex: as which in terms of whats happening i do not know
"Or nor" - two different ways of doing something
Ex: do you think i will kill nor poison your son?
"Such as"
Ex: This is Rin, such as fragile as a glass frame!
"So ever"
Ex: do not mess this house what so ever as im watching you
"Much to my <insert word idk>"
Ex: as much to my dismay, i cannot attend the ceremony
