  • Partial spelling in speech recognition
    Publication number: 20060173680
    Abstract: A method of speech recognition processing is described based on spelling out the initial characters of a word or a sequence of words. Characters representative of an initial portion of an intended user input are collected from a user. In response to a first user action, (e.g., a short pause) at least one name matching hypothesis is provided to the user which is predicted to correspond to the intended user input. Then, in response to a second user action, one name matching hypothesis is selected as representing the intended user input.
