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.
Claims20
A system for mobile device text entry, comprising:
- a text recognition component that obtains a set of inputs from a text entry component, and produces a set of observations based on the inputs;
- a voice recognition component that obtains audio data from an audio capture component, and produces a set of observations based on the audio data;
- and
- a predictive component that combines the observations from the text recognition component and the voice recognition component into a concatenated observation sequence, and generates a textual output based on the concatenated observation sequence.
A method for mobile device text entry, comprising:
- generating a first set of observations based on user inputs obtained via a first input device;
- generating a second set of observations based on user inputs obtained via a second input device;
- combining the first set of observations and the second set of observations to produce a set of combined observations;
- and
- producing a textual output based at least in part on the combined observations.
A system for mobile device text entry, comprising:
- means for generating a first set of observations based on user inputs obtained via a touch screen display that provides a graphical key interface, wherein users select at least one character by pressing the character on the interface;
- means for generating a second set of observations based on user inputs obtained via an audio capture device;
- 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 concatenated observations by using at least one of a Viterbi decoder, or a Hidden-Markov Model.
