摘要： A microphone array having at least three microphones provides a captured signal. Spatial noise suppression estimates a desired signal from a captured signal using spatio-temporal distribution of the speech and the noise. In particular, spatial information indicative of at least two quantities of direction are used. A first quantity is based on a first combination of the signals from the at least three microphones, a second quantity is based on a second combination of the signals of the at least three microphones.

摘要： An index for searching spoken documents having speech data and text meta-data is created by obtaining probabilities of occurrence of words and positional information of the words of the speech data and combining it with at least positional information of the words in the text meta-data. A single index can be created because the speech data and the text meta-data are treated the same and considered only different categories.

摘要翻译： 用于搜索具有语音数据和文本元数据的口头文档的索引是通过获得单词的发生概率和语音数据的单词的位置信息并将其与文本元数据中的单词的至少位置信息进行组合来创建的 。 可以创建单个索引，因为语音数据和文本元数据被视为相同，仅被认为是不同的类别。

摘要： A method of indexing a speech segment includes identifying at least two alternative word sequences based on the speech segment. For each word in the alternative sequences, information is placed in an entry for the word in the index. The information indicates the position of the word in at least one of the alternative sequences.

摘要： A method of modeling a speech recognition system includes decoding a speech signal produced from a training text to produce a sequence of predicted speech units. The training text comprises a sequence of actual speech units that is used with the sequence of predicted speech units to form a confusion model. In further embodiments, the confusion model is used to decode a text to identify an error rate that would be expected if the speech recognition system decoded speech based on the text.

摘要： A method of identifying problems in a speech recognition application is provided and includes the step of obtaining a speech application call log containing log data on question-answer (QA) states and transitions. Then, in accordance with the method, for each of a multiple transitions between states, a parameter is generated which is indicative of a gain in a success rate of the speech recognition application if all calls passing through the transition passed instead through other transitions. In exemplary embodiments, the parameter is an Arc Cut Gain in Success Rate (ACGSR) parameter. Methods of generating the ACGSR, as well as systems and tools for aiding developers are also disclosed.

摘要： A method of producing at least one possible sequence of vocal tract resonance (VTR) for a fixed sequence of phonetic units, and producing the acoustic observation probability by integrating over such distributions is provided. The method includes identifying a sequence of target distributions for a VTR sequence corresponding to a phone sequence with a given segmentation. The sequence of target distributions is applied to a finite impulse response filter to produce distributions for possible VTR trajectories. Then these distributions are applied to a linearized nonlinear function to produce the acoustic observation probability for the given sequence of phonetic units. This acoustic observation probability is used for phonetic recognition.

摘要： A method and apparatus are provided for training and using a hidden conditional random field model for speech recognition and phonetic classification. The hidden conditional random field model uses features, at least one of which is based on a hidden state in a phonetic unit. Values for the features are determined from a segment of speech, and these values are used to identify a phonetic unit for the segment of speech.
