In Spanish, when we want to quote someone's phrase inside a text, we usually write (" ") while (« ») are not very common since they're more use when someone want to quote a frase that has another quote inside. Ex: «Antonio me dijo: “Vaya auto que se ha comprado Julián”» You can see more information in this link, I hope I've answered your question :) http://lema.rae.es/dpd/?key=comillas

I agree with DonHolgo. You can use «these» or “these”, and in some cases it's acceptable to use 'these'. The most commonly used ones are «these ones», but as "these" are easier to type with a keyboard, its use is becoming more widespread :)

Hi there Jonathan! When you want to quote someone's phrase inside a text you are writing, you have to use (" "). When you want to denote a dialog, you use (-). Espero haberte ayudado. Saludos! :)

Spanish typography normally uses «this» or “this” (opening one looking like a 66, closing one like a 99, just like in English), the latter also in single form. See: http://es.wikipedia.org/wiki/Comillas
