摘要： Disclosed herein are methods for presenting speech from a selected text that is on a computing device. This method includes presenting text on a touch-sensitive display and having that text size within a threshold level so that the computing device can accurately determine the intent of the user when the user touches the touch screen. Once the user touch has been received, the computing device identifies and interprets the portion of text that is to be selected, and subsequently presents the text audibly to the user.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for modifying the prosody of synthesized speech based on an associated speech act. A system configured according to the method embodiment (1) receives text, (2) performs an analysis of the text to determine and assign a speech act label to the text, and (3) converts the text to speech, where the speech prosody is based on the speech act label. The analysis performed compares the text to a corpus of previously tagged utterances to find a close match, determines a confidence score from a correlation of the text and the close match, and, if the confidence score is above a threshold value, retrieving the speech act label of the close match and assigning it to the text.

摘要： A process and system for partitioning hybrid markup language documents (HMLDs) is disclosed. Content from an HMLD is copied to one or more output markup language documents (MLDs), which may be well-formed or valid MLDs. The HMLD is segmented at partition boundaries within the document, while state information is recorded in a tag stack. The state information is used to complete the output MLD, which may be sent to a software module for processing. The HMLDs and MLDs may be well-formed or valid extensible markup language (XML) documents.

摘要： Disclosed herein are systems, computer-implemented methods, and computer-readable media for speech recognition. The method includes receiving speech utterances, assigning a pronunciation weight to each unit of speech in the speech utterances, each respective pronunciation weight being normalized at a unit of speech level to sum to 1, for each received speech utterance, optimizing the pronunciation weight by (1) identifying word and phone alignments and corresponding likelihood scores, and (2) discriminatively adapting the pronunciation weight to minimize classification errors, and recognizing additional received speech utterances using the optimized pronunciation weights. A unit of speech can be a sentence, a word, a context-dependent phone, a context-independent phone, or a syllable. The method can further include discriminatively adapting pronunciation weights based on an objective function. The objective function can be maximum mutual information (MMI), maximum likelihood (MLE) training, minimum classification error (MCE) training, or other functions known to those of skill in the art. Speech utterances can be names. The speech utterances can be received as part of a multimodal search or input. The step of discriminatively adapting pronunciation weights can further include stochastically modeling pronunciations.

摘要： A system and method for improving the response time of text-to-speech synthesis utilizes “triphone contexts” (i.e., triplets comprising a central phoneme and its immediate context) as the basic unit, instead of performing phoneme-by-phoneme synthesis. The method comprises a method of generating a triphone preselection cost database for use in speech synthesis, the method comprising 1) selecting a triphone sequence u1-u2-u3, 2) calculating a preselection cost for each 5-phoneme sequence ua-u1-u2-u3-ub, where u2 is allowed to match any identically labeled phoneme in a database and the units ua and ub vary over the entire phoneme universe and 3) storing a group of the selected triphone sequences exhibiting the lowest costs in a triphone preselection cost database.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for speech synthesis. A system practicing the method receives a set of ordered lists of speech units, for each respective speech unit in each ordered list in the set of ordered lists, constructs a sublist of speech units from a next ordered list which are suitable for concatenation, performs a cost analysis of paths through the set of ordered lists of speech units based on the sublist of speech units for each respective speech unit, and synthesizes speech using a lowest cost path of speech units through the set of ordered lists based on the cost analysis. The ordered lists can be ordered based on the respective pitch of each speech unit. In one embodiment, speech units which do not have an assigned pitch can be assigned a pitch.

摘要： A system and method for improving the response time of text-to-speech synthesis using triphone contexts. The method includes identifying a set of triphone sequences, tabulating the set of triphone sequences using a plurality of contexts, where each context specific triphone sequence of the plurality of context specific triphone sequences has a top N triphone units made of the triphone units having lowest target costs when each triphone unit is individually combined into a 5-phoneme combination. Input texts having one of the contexts are received, and one of the context specific triphone sequences is selected based on the context. Input text is then synthesized using the context specific triphone sequence.

摘要： Disclosed herein are systems, computer-implemented methods, and computer-readable storage media for recognizing speech by adapting automatic speech recognition pronunciation by acoustic model restructuring. The method identifies an acoustic model and a matching pronouncing dictionary trained on typical native speech in a target dialect. The method collects speech from a new speaker resulting in collected speech and transcribes the collected speech to generate a lattice of plausible phonemes. Then the method creates a custom speech model for representing each phoneme used in the pronouncing dictionary by a weighted sum of acoustic models for all the plausible phonemes, wherein the pronouncing dictionary does not change, but the model of the acoustic space for each phoneme in the dictionary becomes a weighted sum of the acoustic models of phonemes of the typical native speech. Finally the method includes recognizing via a processor additional speech from the target speaker using the custom speech model.
