Incremental training of a speech recognizer for a new language

摘要

To implement a speech recognizer for a language in conditions of substantial unavailability of related speech training material the first step (1, 2) is, based on related speech training material, a multilingual speech recognizer (2) for a plurality of known languages. The recognizer for such given language (5) is then implemented by interpolation (4) starting from the said multilingual recognizer (2). The recognizer (5) generated in this fashion is susceptible of being subsequently refined based on related speech training material acquired online (4) during later use.
