Nombres de varios sonidos en euskara: http://www.hiru.com/euskara/glosarioa

Fonatari http://www.fonatari.org/ Great website with sounds of euskara and audio and video samples from all the dialects (in the video samples you can actually see how the sound is being articulated!) It also contains other interesting scientific data about the language.

A website that pronounces certain given phrases and words (greetings and courtesy patterns, frequent questions, affirmations, denials, doubts, colours, numbers, dates etc) - with translations in Spanish, French and English: http://www.euskomedia.org/esku-eskura/Dw_dok/MARKOAK.htm

I found this text-to-speech system for Basque and I am extatic about it :) http://bips.bi.ehu.es/tts/tts_en.html# You can even save the audio files (I only tried with the mp3 format) for further use! Isn't that great!?
