1. A system for mobile device text entry, comprising:
- memory storing computer readable instructions configured for executing a plurality of components; and
a processor, coupled to the memory and operable to execute the instructions, the plurality of components comprising;
a text recognition component that obtains a set of inputs from a text entry component, determines a set of digitized coordinates for the set of inputs, and produces a first set of observations based on a set of possible intended user inputs and the digitized coordinates, wherein the text entry component is a touch screen display;
a voice recognition component that obtains audio data from an audio capture component, and produces a second set of observations based on the audio data, wherein the audio capture component obtains the audio data concurrently as the text entry component obtains the set of inputs; and
a predictive component that combines the first set of observations and the second set of observations into a concatenated observation sequence, and generates a textual output based on the concatenated observation sequence, wherein the generated textual output includes a first predetermined character that is predicted by the predictive component based on (a) a substitute character received by the text entry component, the substitute character is different from the first predetermined character, and (b) pronunciation of the first predetermined character received by the audio capture component.

Abstract
The invention relates to systems and or methodologies for enabling combined speech and touch inputs for observation symbol mappings. More particularly, the current innovation leverages the commonality of touch screen display text entry and speech recognition based text entry to increase the speed and accuracy of text entry via mobile devices. Touch screen devices often contain small and closely grouped keypads that can make it difficult for a user to press the intended character, by combining touch screen based text entry with speech recognition based text entry the aforementioned limitation can be overcome efficiently and conveniently.

13. A system for mobile device text entry, comprising:
-
means for generating a first set of observations based on a set of possible intended user inputs and a determined set of digitized coordinates associated with the set of possible intended user inputs obtained via a touch screen display that provides a graphical key interface, wherein users select at least one unintended character by pressing at a location on the graphical key interface proximate to the location of the unintended character; means for generating a second set of observations based on user inputs obtained via an audio capture device, wherein user inputs via the touch screen display and the audio capture device are obtained concurrently; and means for combining the first set of observations and the second set of observations to produce a set of concatenated observations; and means for producing a textual output based on the set of concatenated observations, wherein the produced textual output includes a first predetermined character that is predicted based on (a) a substitute character received by the graphical key interface, the substitute character is different from the first predetermined character, and (b) pronunciation of the first predetermined character received by the audio capture device. - View Dependent Claims (14, 15, 16)
