David makes half a dozen trips to the Orient each year, with strategic stops in Japan. This latest is an extension of their previous 4 CDs focusing on vocabulary. It uses graphics and audio to present sets of common vocabulary and voice recognition to test memory and pronunciation. These are presented in order of frequency.
Users can choose two modes, repetition or recall.
Words missed are recycled and mixed with correct ones using an algorithm that increases the frequency of presentation of words the user finds difficult. The list is dynamic, with an adjustable number or pool of words included at any one time. Users are fed new words as practiced ones are mastered. The smaller the list of words, the more frequent the problem ones are repeated. In the recall mode, the user is presented with the graphic and must say the target word without prompting.
