JS funcation - code review

// Write a function translate() that will translate a text into "rövarspråket". 
// That is, double every consonant and place an occurrence of "o" in between. 
// For example, translate("this is fun") should return the string "tothohisos isos fofunon".

var character = []

function translate(sentence) {
  var new_str = sentence.split("");
 
  for (var i = 0; i < new_str.length; i++) {
    if (new_str[i].match(/[aeiou | AEIOU]/)) {
      character.push(new_str[i]);
    } else if (new_str[i].match(/\s/)) {
      character.push(" ");
    } else if (!new_str[i].match(/[aeiou]/)) {
      character.push(new_str[i] + "o" + new_str[i]);
    }
