Abstract: An input service manages multiple edit buffers and multiple input processors for processing user input. The input service is available to any number of applications. The input service manages the edit buffers and the input processors such that at any given time, only one edit buffer is active and only one input processor is active. The multiple input processors can include one keyboard input processor and any number of non-keyboard input processors.

Abstract: The system disclosed herein employs a method for facilitating access to supplemental information relating to text items entered into an editing application program by a speech recognition system, e.g. alternate translations of utterances stored in a dictation event database (DEDB). A speech event database (SEDB) associated with the editing program is maintained so as to contain text items entered by said speech recognition system and context information identifying preceding and following text items. In response to a user initiated change in the editing point, a context list is created characterizing a region of text around the new editing point. The speech SEDB event database is searched for text items matching items in said context list thereby to create a mapping of the list to the SEDB. The speech event database is then used as an index into said dictation event database, e.g. for correcting previously misrecognized utterances.
