Declan's Spanish FlashCards is a fully configurable audio-based Spanish vocabulary flash-card program. The program has been designed to help students learn a large number of Spanish words as quickly as possible in a systematic but fun and simple way.

The program incorporates an audio feature that uses a native speaker's voice recordings of a word's pronunciation to aid the learning process. Word Files comprising over 3800 of the most frequently used Spanish words, each with a native speaker's voice recording of its pronunciation, are available for free download.
