+Use `SpeechSynthesisUtterance.voice` and `indow.speechSynthesis.getVoices()` to convert a message to speech.
+Use `window.speechSynthesis.speak()` to play the message.

+### Number to array of digits
+
+Convert the number to a string, use `split()` to convert build an array.
+Use `Array.map()` and `parseInt()` to transform each value to an integer. 
+
+```js
+const digitize = n => (''+n).split('').map(i => parseInt(i));
+// digitize(2334) -> [2, 3, 3, 4]

 ### Ordinal suffix of number
 
 Use the modulo operator (`%`) to find values of single and tens digits.
