摘要： In response to a word of a text sequence, a first part-of-speech (POS) tag is generated using a statistical part-of-speech (POS) tagger based on a corpus of trained text sequences, each representing a likely POS of a word for a given text sequence. A second POS tag is generated using a rule-based POS tagger based on a set of one or more rules associated with a type of an application associated with the text sequence. A final POS tag is assigned to the word of the text sequence for TTS synthesis based on the first POS tag and the second POS tag.

摘要： According to one embodiment, a latent semantic mapping (LSM) space is generated from a collection of a plurality of documents, where the LSM space includes a plurality of document vectors, each representing one of the documents in the collection. For each of the document vectors considered as a centroid document vector, a group of document vectors is identified in the LSM space that are within a predetermined hypersphere diameter from the centroid document vector. As a result, multiple groups of document vectors are formed. The predetermined hypersphere diameter represents a predetermined closeness measure among the document vectors in the LSM space. Thereafter, a group from the plurality of groups is designated as a cluster of document vectors, where the designated group contains a maximum number of document vectors among the plurality of groups.

摘要： Pronunciation for an input word is modeled by generating a set of candidate phoneme strings having pronunciations close to the input word in an orthographic space. Phoneme sub-strings in the set are selected as the pronunciation. In one aspect, a first closeness measure between phoneme strings for words chosen from a dictionary and contexts within the input word is used to determine the candidate phoneme strings. The words are chosen from the dictionary based on a second closeness measure between a representation of the input word in the orthographic space and orthographic anchors corresponding to the words in the dictionary. In another aspect, the phoneme sub-strings are selected by aligning the candidate phoneme strings on common phoneme sub-strings to produce an occurrence count, which is used to choose the phoneme sub-strings for the pronunciation.

摘要： Speech or acoustic signals are processed directly using a hybrid stochastic language model produced by integrating a latent semantic analysis language model into an n-gram probability language model. The latent semantic analysis language model probability is computed using a first pseudo-document vector that is derived from a second pseudo-document vector with the pseudo-document vectors representing pseudo-documents created from the signals received at different times. The first pseudo-document vector is derived from the second pseudo-document vector by updating the second pseudo-document vector directly in latent semantic analysis space in response to at least one addition of a candidate word of the received speech signals to the pseudo-document represented by the second pseudo-document vector. Updating precludes mapping a sparse representation for a pseudo-document into the latent semantic space to produce the first pseudo-document vector. A linguistic message representative of the received speech signals is generated.

摘要： Methods and apparatus are disclosed for recognizing handwritten characters in response to an input signal from a handwriting transducer. A feature extraction and reduction procedure is disclosed that relies on static or shape information, wherein the temporal order in which points are captured by an electronic tablet may be disregarded. A method of the invention generates and processes the tablet data with three independent sets of feature vectors which encode the shape information of the input character information. These feature vectors include horizontal (x-axis) and vertical (y-axis) slices of a bit-mapped image of the input character data, and an additional feature vector to encode an absolute y-axis displacement from a baseline of the bit-mapped image. It is shown that the recognition errors that result from the spatial or static processing are quite different from those resulting from temporal or dynamic processing. Furthermore, it is shown that these differences complement one another. As a result, a combination of these two sources of feature vector information provides a substantial reduction in an overall recognition error rate. Methods to combine probability scores from dynamic and the static character models are also disclosed.

摘要： A general approach is provided for the combined use of several sources of information in the automatic recognition of a consistent message. For each message unit (e.g., word) the total likelihood score is assumed to be the weighted sum of the likelihood scores resulting from the separate evaluation of each information source. Emphasis is placed on the estimation of weighing factors used in forming this total likelihood. This method can be applied, for example, to the decoding of a consistent message using both handwriting and speech recognition. The present invention includes three procedures which provide the optimal weighing coefficients.
