An apparatus and method are disclosed for providing feedback and guidance to touch screen device users to improve the text entry user experience and performance through the use of indicators such as feedback semaphores. Also disclosed are suggestion candidates, which allow a user to quickly select next words to add to text input data, or replacement words for words that have been designated as incorrect. According to one embodiment, a method comprises receiving text input data, providing an indicator for possible correction of the text input data, displaying suggestion candidates associated with alternative words for the data, receiving a single touch screen input selecting one of the suggestion candidates, and modifying the input data using the word associated with the selected suggestion candidate.

The present invention provides a speech recognition system combined with one or more alternate input modalities to ensure efficient and accurate text input. The speech recognition system achieves less than perfect accuracy due to limited processing power, environmental noise, and / or natural variations in speaking style. The alternate input modalities use disambiguation or recognition engines to compensate for reduced keyboards, sloppy input, and / or natural variations in writing style. The ambiguity remaining in the speech recognition process is mostly orthogonal to the ambiguity inherent in the alternate input modality, such that the combination of the two modalities resolves the recognition errors efficiently and accurately. The invention is especially well suited for mobile devices with limited space for keyboards or touch-screen input.

A system filters documents in a document set retrieved from a document store in response to a query. The system obtains a first set of logical forms based on a selected one of the query and the documents in the document set. The system obtains a second set of logical forms based on another of the query and the documents in the document set. The system then uses natural language processing techniques to modify the first logical forms to obtain a modified set of logical forms. The system filters documents in the document set based on a predetermined relationship between the modified set of logical forms and the second set of logical forms.

A text input method is described for an electronic apparatus having a user interface with text input means and a display screen. Word completion functionality is provided for predicting word candidates for partial word inputs made by the user with the text input means. The method involves receiving a partial word input from the user and deriving a set of word completion candidates using the word completion functionality. Each of the word completion candidates in the set has a prefix and a suffix, wherein the prefix corresponds to the partial word input. The method also involves presenting the suffices for at least a sub set of the word completion candidates in a predetermined area on the display screen, wherein each of the presented suffices is made selectable for the user.

A reduced keyboard apparatus and method for use with small-sized communications and computing devices. Input via the keyboard is performed using fingers or thumbs. The keyboard is characterized by having no discrete boundaries between the included character spaces. The direction and the destination area of a keystroke do not have to be accurate and may correspond to a plurality of included character spaces. Each of the possible characters is provided with a probability value, continuously redefined according to the specific keyboard area activated by the keystroke. The input of a word is defined by a sequence of keystrokes corresponding to the letters of the word. Subsequent to the completion of a keystroke sequence, the apparatus and method determine the identity of the word through a disambiguation process based on area density distribution. The apparatus and method enable fast, natural, and intuitive tapping on small keyboards having character areas much smaller than the user's fingers while at the same time provide highly efficient word determination.

A method and system are provided for text-to-speech synthesis with personalized voice. The method includes receiving an incidental audio input (403) of speech in the form of an audio communication from an input speaker (401) and generating a voice dataset (404) for the input speaker (401). The method includes receiving a text input (411) at the same device as the audio input (403) and synthesizing (312) the text from the text input (411) to synthesized speech including using the voice dataset (404) to personalize the synthesized speech to sound like the input speaker (401). In addition, the method includes analyzing (316) the text for expression and adding the expression (315) to the synthesized speech. The audio communication may be part of a video communication (453) and the audio input (403) may have an associated visual input (455) of an image of the input speaker. The synthesis from text may include providing a synthesized image personalized to look like the image of the input speaker with expressions added from the visual input (455).

A data entry system is provided using a virtual dynamic keypad having at least four keys, wherein to four of the keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined during the entry of text. A text entry system is also provided using a virtual keypad having at least four keys wherein to four of its keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined based on a calibrating procedure provided by the user. A data entry system is provided using a pointing device providing different pointing directions wherein each of the pointing directions duplicates a key of a predefined virtual keypad model wherein to at least some of its keys substantially all of the letters of a language are distributively assigned.

There is disclosed an enhanced text entry system which uses word-level analysis to correct inaccuracies automatically in user keystroke entries on reduced-size or virtual keyboards. A method and system are defined which determine one or more alternate textual interpretations of each sequence of inputs detected within a designated auto-correcting region. The actual interaction locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed or offered for selection, where the distance from each interaction location to each corresponding intended character may in general increase with the expected frequency of the intended word in the language or in a particular context. Likewise, in a virtual keyboard system, the keys actuated may differ from the keys actually associated with the letters of the word interpretations. Each such sequence corresponds to a complete word, and the user can easily select the intended word from among the generated interpretations. Additionally, when the system cannot identify a sufficient number of likely word interpretation candidates of the same length as the input sequence, candidates are identified whose initial letters correspond to a likely interpretation of the input sequence.

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device. If a field into which text is being entered is determined to be a special input field, a disambiguated result can be sought first from a predetermined data source prior to seeking results from other data sources on the device.

In embodiments of the present invention improved capabilities are described for a mobile environment speech processing facility. The present invention may provide for the entering of text into a software application resident on a mobile communication facility, where recorded speech may be presented by the user using the mobile communications facility's resident capture facility. Transmission of the recording may be provided through a wireless communication facility to a speech recognition facility, and may be accompanied by information related to the software application. Results may be generated utilizing the speech recognition facility that may be independent of structured grammar, and may be based at least in part on the information relating to the software application and the recording. The results may then be transmitted to the mobile communications facility, where they may be loaded into the software application.

There is disclosed an enhanced text entry system which uses word-level analysis to automatically correct inaccuracies in user keystroke entries on reduced keyboards such as those implemented on a touch-sensitive panel or display screen, or on mechanical keyboard systems. A method and system are defined which determine one or more alternate textual interpretations of each sequence of inputs detected within a designated auto-correcting keyboard region. The actual contact locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed or offered for selection, where the distance from each contact location to each corresponding intended character may in general increase with the expected frequency of the intended word in the language or in a particular context. Likewise, in a mechanical keyboard system, the keys actuated may differ from the keys actually associated with the letters of the word interpretations. Each such sequence corresponds to a complete word, and the user can easily select the intended word from among the generated interpretations. Additionally, when the system cannot identify a sufficient number of likely word interpretation candidates of the same length as the input sequence, candidates are identified whose initial letters correspond to a likely interpretation of the input sequence. The approach utilizes the information contained in the entire sequence of keystrokes corresponding to a word in order to determine the user's likely intention for each character of the sequence. The system also accommodates punctuation characters such as hyphens or apostrophes that are commonly embedded in words such as hyphenated compounds and contractions in English, and characters with special diacritics such as are commonly found in various European languages, e.g., diacritic accent. Special functions may be applied depending on where the user touches the intended string in a displayed word selection list. Once the user selects the desired string, it is automatically “accepted” for output and the next input detected starts a new input sequence corresponding to the entry of a next word.
