摘要： A speaker authentication system includes an input receptive of user speech from a user. An extraction module extracts acoustic correlates of aspects of the user's physiology from the user speech, including at least one of glottal source parameters, formant related parameters, timing characteristics, and pitch related qualities. An output communicates the acoustic correlates to an authentication module adapted to authenticate the user by comparing the acoustic correlates to predefined acoustic correlates in a datastore.

摘要： Unstructured voice information from an incoming caller is processed by automatic speech recognition and semantic categorization system to convert the information into structured data that may then be used to access one or more databases to retrieve associated supplemental data. The structured data and associated supplemental data are then made available through a presentation system that provides information to the call center agent and, optionally, to the incoming caller. The system thus allows a call center information processing system to handle unstructured voice input for use by the live agent in handling the incoming call and for storage and retrieval at a later time. The semantic analysis system may be implemented by a global parser or by an information retrieval technique, such as latent semantic analysis. Co-occurrence of keywords may be used to associate prior calls with an incoming call to assist in understanding the purpose of the incoming call.
摘要翻译：来自呼叫者的非结构化语音信息由自动语音识别和语义分类系统处理，以将信息转换成结构化数据，然后可以用于访问一个或多个数据库以检索相关联的补充数据。结构化数据和相关的补充数据然后通过向呼叫中心代理提供信息并且可选地提供给传入呼叫者的呈现系统可用。因此，该系统允许呼叫中心信息处理系统处理非结构化语音输入以供实时代理使用以处理来话呼叫并在以后的时间进行存储和检索。语义分析系统可以由全局解析器或诸如潜在语义分析之类的信息检索技术来实现。关键字的共现可以用于将先前的呼叫与呼入呼叫相关联，以帮助理解来话呼叫的目的。

摘要： A phoneticizer converts spelled words or names into one or an n-best number of phonetic transcriptions. The n-best transcriptions may be generated from a single transcription using a confusion matrix. These n-best transcriptions are then transformed into hybrid units. Preferably only the most frequently encountered units are stored as syllables, with the remainder being stored as smaller units such as demi-syllables or phonemes. Voice input is then used to rescore the n-best transcriptions and these are stored preferably as speaker-independent, similarity-based hybrid units concatenated into a string representing the spelled word.
摘要翻译：拼音者将拼写的单词或名称转换为一个或最多数量的语音转录。可以使用混淆矩阵从单个转录产生n个最佳转录。然后将这些n个最佳转录转化成混合单位。优选地，只有最常遇到的单元被存储为音节，其余的被存储为更小的单位，例如音节或音素。然后，语音输入用于重新排列n个最佳的转录，并且这些被优选地存储为与说明者无关的，基于相似度的混合单元连接成表示拼写单词的字符串。

摘要： The acoustic speech signal is decomposed into wavelets arranged in an asymmetrical tree data structure from which individual nodes may be selected to best extract local features, as needed to model specific classes of sound units. The wavelet packet transformation is smoothed through integration and compressed to apply a non-linearity prior to discrete cosine transformation. The resulting subband features such as cepstral coefficients may then be used to construct the speech recognizer's speech models. Using the local feature information extracted in this manner allows a single recognizer to be optimized for several different classes of sound units, thereby eliminating the need for parallel path recognizers.
摘要翻译：声学语音信号被分解成以不对称树数据结构排列的小波，根据需要可以选择各个节点以最佳地提取局部特征，以模拟特定类别的声音单元。小波包变换通过积分进行平滑，并进行压缩，以在离散余弦变换之前应用非线性。所得到的子带特征如倒谱系数可以用于构建语音识别器的语音模型。使用以这种方式提取的局部特征信息允许为多个不同类别的声音单元优化单个识别器，从而消除对并行路径识别器的需要。

摘要： The audio source is spectrally shaped by filtering in the time domain to approximate or emulate a standardized or target microphone input channel. The background level is adjusted by adding noise to the time domain signal prior to the onset of speech to set a predetermined background noise level based on a predetermined target. The audio source is then monitored in real time and the signal-to-noise ratio is adjusted by adding noise to the time domain signal, in real time, to maintain a signal-to-noise ratio based on a predetermined target value. The normalized audio signal may be applied to both training speech and test speech. The resultant normalization minimizes the mismatch between training and testing and also improves other speech processing functions, such as speech endpoint detection.
摘要翻译：音频源通过在时域中过滤来近似或模拟标准化或目标麦克风输入通道进行频谱成形。通过在语音开始之前对时域信号增加噪声来调整背景电平，以基于预定目标设定预定的背景噪声电平。然后，实时监视音频源，实时地通过对时域信号增加噪声来调整信噪比，以基于预定目标值维持信噪比。归一化音频信号可以应用于训练语音和测试语音两者。最终归一化使训练和测试之间的不匹配最小化，并且还改善了其他语音处理功能，例如语音端点检测。

摘要： A new speaker provides speech from which comparison snippets are extracted. The comparison snippets are compared with initial snippets stored in a recorded snippet database that is associated with a concatenative synthesizer. The comparison of the snippets to the initial snippets produces required sound units. A greedy selection algorithm is performed with the required sound units for identifying the smallest subset of the input text that contains all of the text for the new speaker to read. The new speaker then reads the optimally selected text and sound units are extracted from the human speech such that the recorded snippet database is modified and the speech synthesized adopts the voice quality and characteristics of the new speaker.

摘要： A system and method for identifying a user of a handheld device is herein disclosed. The device implementing the method and system may attempt to identify a user based on signals that are incidental to a user's handling of the device. The signals are generated by a variety of sensors dispersed along the periphery or within the housing. The sensors range may include touch sensors, inertial sensors, acoustic sensors, pulse oximiters, and a touchpad. Based on the sensors and corresponding signals, identification information is generated. The identification information is used to identify the user of the handheld device. The handheld device may implement various statistical learning and data mining techniques to increase the robustness of the system. The device may also authenticate the user based on the user drawing a circle, or other shape.

摘要： A library of mouth shapes is created by separating speaker-dependent and speaker independent variability. Preferably, speaker dependent variability is modeled by a speaker space while the speaker independent variability (i.e. context dependency), is modeled by a set of normalized mouth shapes that need be built only once. Given a small amount of data from a new speaker, it is possible to construct a corresponding mouth shape library by estimating a point in speaker space that maximizes the likelihood of adaptation data and by combining speaker dependent and speaker independent variability. Creation of talking heads is simplified because creation of a library of mouth shapes is enabled with only a few mouth shape instances. To build the speaker space, a context independent mouth shape parametric representation is obtained. Then a supervector containing the set of context-independent mouth shapes is formed for each speaker included in the speaker space. Dimensionality reduction is used to find the areas of the speaker space.
