Adaptation for statistical language model

A computer-implemented phonetic system, comprising:

• a history component configured to process user input history for conversion of a phonetic string during a conversion process;
• a restriction component configured to apply restrictions to the user input history during the conversion process to suppress unexpected appearance of words, the restriction component applies a restriction that boosts a probability based on context-dependent probability differences, the history includes context-dependent probability difference as short-term memory and frequency of preceding context of a word as long-term memory;
• an adaptation component configured to adapt the conversion process to the user input history based on the restrictions;
• and
• a microprocessor that executes computer-executable instructions associated with the history component, the restriction component, and the adaptation component.

A computer-implemented phonetic method, performed by a computer system executing machine-readable instructions, the method comprising acts of:

• processing user input history for conversion of a phonetic string during a conversion process;
• applying restrictions to the user input history during the conversion process to suppress unexpected appearance of words, the history includes context-dependent probability difference as short-term memory and frequency of preceding context of a word as long-term memory, wherein a restriction is applied that boosts a probability based on the context-dependent probability differences;
• and
• adapting the conversion process to the user input history based on the restrictions.
