LingvoSoft Talking Dictionary for Palm translates English-Spanish & vice versa with 400K word database. Quick Search, Vector Ultima spell-checker & other features simplify searching. Provides instant back translations.

One of the things I really appreciated about this software was how easy it was to use. All you have to do is select an English word, and with one click, the speech synthesizer will pronounce it for you. The synthesizer is based on formant synthesis, which models the sounds of natural language to create a human voice simulation.
In addition to its ease of use, this dictionary is also incredibly comprehensive. It features a searchable database of 400,000 words and phrases, each entry completed with part of speech information and several translation options for all polysemantic words.
But perhaps what I appreciated most about this software is the combination of ease-of-use and flexibility it offers. Some of its special features include advanced English speech synthesis, the MorphoFinder function that helps you find source words, and the Spell-checker Vector Ultima that allows you to enter a word as you hear it and choose a spelling option from the list of suggestions.
Some of the general features of this software include an overview of all dictionary entries in the Main List, an overview of all possible translations of the selected word in the Translations' List, quick back translation for proof of correct understanding, and a quick search function that displays words starting with specific letter combinations. Additionally, you can easily switch between languages by pressing the pop-up trigger in the upper right corner of the interface.
Overall, I would highly recommend this software to anyone looking to improve their language skills on the go. With its comprehensive database, easy-to-use interface, and extensive selection of features, the LingvoSoft Talking Dictionary English Spanish for Palm OS is a must-have for anyone serious about language acquisition.
