Abstract
A method and system are provided in which a speech recognition system and one or more other input modalities are run in parallel. The system is especially useful in easing the Chinese input obstruction due to the difficulty of conforming Chinese ideograms to typical processor system input devices. The system allows a user to concurrently input information using different modalities. For example, a user may input spoken words and written characters (or data through other modalities). Each modality produces a list of possible words and their probability of being the input. If the most probable possible word is the same for both modalities then it is selected as the input. If not, an acoustic profile of the most probable speech input or an average acoustic profile of the possible speech inputs is used to validate a possible word of the other modalities or present a list of more probable possibilities to the user. The user may modify the written characters (or other input) from the provided possibilities. In this way the differing input modalities do not interfere with each other, but instead complement each other.
