Adding a @return annotation to constructors is generally not recommended as a constructor does not have a meaningful return value.

It seems like $domNode->childNodes of type object<DOMNodeList> is incompatible with the declared type object<Cion\TextToSpeech\Sources\DOMNodeList> of property $_nodeList.
