Yes, there is also "el país vasco-francés".
I've found this interesting web page about Euskera in the Internet (in English):
http://buber.net/Basque/
And in the following link you can hear some Basque words (there are another languages, too):

But basically, the following sounds are which are different from Spanish ones:
g: g suave castellana, como gue/gui
tx (txe): como la ch castellana
ts (tsi): un poco más suave que la ch castellana
tz (tza): parecido a la zz italiana de “pizza”
z: s sibilante (en algunos sitios = z castellana)
x = sh inglesa
il = ll castellana
in = ñ castellana
