Adaptive vocabulary improvement

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to:

• monitor text or audio data of a computer-based communication of a user for a new learned word by comparing words in the computer-based communication of the user with words in a language in a stored known word list of the user;
• recognize a word in the computer-based communication as the new learned word for the user in the language based on the monitoring;
• register the new learned word as a registered new learned word in a new learned word database of the user, the new learned word database having a data structure that includes a memorization level of the new learned word by the user;
• associate the registered new learned word with one or more synonyms in the language in a known word library of the user, the known word library including words known to the user;
• track uses of the one or more synonyms by the user in text or audio data from additional computer-based communications, wherein the tracking includes recording word use frequency in a table of use frequency of related known words of the user;
• identify a sentence in a new computer-based communication of the user that contains one of the one or more synonyms;
• and
• suggest to the user a suggested new sentence to replace the sentence in the new computer-based communication of the user in real-time based on the identifying, wherein the suggested new sentence includes the new learned word in place of the one of the one or more synonyms,
• wherein the recognizing the word in the computer-based communication as the new learned word of the user is further based on monitoring activity of the user with respect to Internet of Things (IoT) devices, the activity including user interactions with a voice activated personal assistant configured to track spoken words of the user and a context in which each of the spoken words is used.

A system comprising:

• a processor, a computer readable memory, and a computer readable storage medium;
• program instructions to monitor text data of a computer-based communication of a user for a new learned word by comparing words in the computer-based communication of the user with words in a language in a stored known word list of the user;
• program instructions to recognize a word in the computer-based communication as a new learned word for the user in the language based on the monitoring;
• program instructions to register the new learned word as a registered new learned word in a new learned word database of the user, the new learned word database having a data structure that includes a memorization level of the new learned word by the user;
• program instructions to associate the registered new learned word with one or more synonyms in the language in a known word library of the user, the known word library including words known to the user;
• program instructions to track uses of the one or more synonyms by the user in text data from additional computer-based communications, wherein the tracking includes recording word use frequency in a table of use frequency of related known words of the user;
• program instructions to identify a sentence in a new computer-based communication of that contains one of the one or more synonyms;
• and
• program instructions to send to the user a suggested new sentence that to replace the sentence in the new computer-based communication of the user in real-time based on the identifying, wherein the suggested new sentence includes the new learned word in place of the one of the one or more synonyms,
• wherein the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory, and
• wherein the recognizing the word in the computer-based communication as the new learned word of the user is further based on monitoring activity of the user with respect to Internet of Things (IoT) devices, the activity including user interactions with a voice activated personal assistant configured to track spoken words of the user and a context in which each of the spoken words is used.
