Abstract: Methods and apparatus for quickly selecting an optimal excitation waveform from a codebook are presented herein. To reduce the number of computations required to choose the optimal codebook vector, a subset of codevectors are selected based upon optimal pulse locations, wherein the subset of codevectors form a subcodebook. Rather than searching the entire codebook, only the entries of the subcodebook are searched.

Abstract: It is an objective of the present invention to provide an optimized method of selection of the encoding mode that provides rate efficient coding of input speech. A rate determination logic element (14) selects a rate at which to encode speech. The rate selected is based upon the target matching signal to noise ration computed by a TMSNR computation element (2), normalized autocorrelation computed by a NACF computation element (4), a zero crossings count determined by a zero crossings counter (6), the prediction gain differential computed by a PGD computation element (8) and the interframe energy differential computed by a frame energy differential element (10).

Abstract: A spoken user interface for speech-enabled devices includes a processor and a set of software instructions that are executable by the processor and stored in nonvolatile memory. A user of the speech-enabled device is prompted to enter a voice tag associated with an entry in a call history of the speech-enabled device. The call history includes lists of incoming and outgoing email messages, and incoming and outgoing telephone calls. The user is prompted to enter a voice tag after associated with a telephone number or email address in the call history after a user-selected number of telephone calls has been sent from the speech-enabled device to that telephone number, or has been sent from the telephone with that telephone number to the speech-enabled device, or after a user-selected number of email messages has been sent from the speech-enabled device to that email address, or has been sent from that email address to the speech-enabled device. The user may populate a phonebook of the speech-enabled device with email addresses by sending an email message to the speech-enabled device from a computer and including additional email addresses in the To: field and/or the CC: field of the email message.

Abstract: A method and apparatus to facilitate service negotiation by a digital telecommunications system that allows a low activity communication to be transmitted by the system over vocoded channels. In one embodiment, once the telecommunication system is noticed that a low activity signal needs to be transmitted, each telecommunication system vocoder involved in the transmission automatically locks into full rate, and where applicable, adjusts the transmission power to reduce frame error rate. Further, the telecommunications system may include any number of wireless links. The invention includes a noticing apparatus coupled to a sensor that receives a low activity communication device attachment and notices the digital telecommunications system that a low activity communication is being initiated or discontinued.

Abstract: A method and apparatus for establishing low activity communication service over vocoded channels in a digital telecommunications system, which may include wireless links. In one embodiment, once the telecommunication system receives a low activity communication signal (402), all vocoders automatical ly lock into a full rate (404) in preparation for transmission. Where applicabl e, the transmission power of the low activity communication signal is adjusted to reduce frame error rate (408). Dynamic adjustments are made continually duri ng transmission (412). The telecommunications system includes apparatus to noti ce the presence of the low activity communication signal.

Abstract: A method and apparatus providing a user interface within a phone that responds to a limited vocabulary of user trained voice commands. The interface allows users to perform all phone handset dialing functions using voice commands. Additionally, users will be able to create and modify entries within a voice recognition phonebook, whereby a number within the voice recognition phonebook can be called by saying the name associated with the number. The user interface provides a combination of voice and LCD displayed user prompts and responses to voice input. The interface responds to user voice commands and performs the command functions based upon matches to previously user trained voice command vocabulary words stored in memory.

Abstract: A method and apparatus for aligning a test signal to a frame interval of a communication system in which an alignment test signal having an alternating pattern of frequencies is generated and transmitted over a communication link that carries the alignment test signal in a sequence of frames. The alignment test signal is received over the communication link as a return alignment test signal and then evaluated for frequency content. The start time of the alignment test signal is adjusted until the frequency content of the return alignment test signal corresponds to the alternating pattern of frequencies.

Abstract: A voice recognition (VR) system is disclosed that utilizes a combination of speaker independent (SI) and speaker dependent (SD) acoustic models. At least one SI acoustic model is used in combination with at least one SD acoustic model to provide a level of speech recognition performance that at least equals that of a purely SI acoustic model. The disclosed hybrid SI/SD VR system continually uses unsupervised training to update the acoustic templates in the one or more SD acoustic models. The hybrid VR system then uses the updated SD acoustic models in combination with the at least one SI acoustic model to provide improved VR performance during VR testing

Abstract: A voice recognition rejection scheme for capturing an utterance includes the steps accepting the utterance, applying an N-best algorithm to the utterance, or rejecting the utterance. The utterance is accepted if a first predefined relationship exists between one or more closest comparison results for the utterance with respect to a stored word and one or more differences between the one or more closest comparison results and one or more other comparison results between the utterance and one or more other stored words. An N-best algorithm is applied to the utterance if a second predefined relationship exists between the one or more closest comparison results and the one or more differences between the one or more closest comparison results and the one or more other comparison results. The utterance is rejected if a third predefined relationship exists between the one or more closest comparison results and the one or more differences between the one or more closest comparison results and the one or more other comparison results. One of the one or more other comparison results may advantageously be a next-closest comparison result for the utterance and another store word. The first, second, and third predefined relationships may advantageously be linear relationships.
