Abstract

Methods and systems for improving speech recognition accuracy is disclosed. The speech recognition accuracy is improved through dynamic verifications of a list of marked words, symbols, phrases or identifiers. According to one embodiment, a counter is designated to one or more words in an identifier that is highly demanded in a voice interactive system. When the counter exceeds a threshold or there is a need, the one or more words are marked and stored in a database. The one or more words are provided to minimize ambiguities between two words/phrases that might be pronounced indistinctly.

Claims

1. A method for responding to a spoken text received from a speech recognition system, the method comprising:

providing a list of marked identifiers, wherein each of the identifiers is selected from a group consisting of one or more words, symbols, one or more entries, an IP address and one or more numerals;

looking up the list in reference to the spoken text upon receiving the spoken text; and

replacing the spoken text when there is a similarity match between one of the marked identifiers and the spoken text.
