eSpindle Learning Inc. has chosen Wizzard's AT&T Natural Voices Speech Engine offering for use in their customized online tutoring of English spelling exercises. The Sebastopol, California based eSpindle Learning is an educational nonprofit organization, dedicated to providing low-cost tutoring support in English spelling through innovative online technology. eSpindle Learning creates custom learning quizzes based on the individual's goals, skills and personal "problem words". Drawing on an extensive database of more than 95,000 words, this new online spelling tutor creates custom learning quizzes based on each user's goals, skill level, and learning profile fostering unlimited learning. Affordable and comprehensive, eSpindle will help users achieve dramatic, measurable and lasting results in building their spelling and vocabulary skills regardless of their age or previous level of proficiency. Users can specify their personal goals and skill level to: receive tutoring to improve verbal skills and school grades; avoid commonly misspelled words; learn English as a second language; enhance home school studies; gain a stronger vocabulary; overcome learning disabilities; and exercise their memorization skills. It also has a custom module that allows members to prepare for the National Spelling Bee. Each word is presented with an on-demand audio file powered by AT&T's Natural Voices speech engine, simple definition, sample sentence and links to online resources. A member's unique database profile registers which words are already mastered and repeats those that need practice until they are reliably learned, all the while tracking work accomplished.
