    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.

    Abstract: Se describen tecnicas para codificar una corriente de audio video que se transmite sobre una red, por ejemplo una red inalambrica o IP, tal como una trama entera de audio y una trama entera de video se transmiten simultaneamente dentro de un periodo requerido para rendir tramas de corriente de audio video por medio de una aplicacion de un receptor; los aspectos de la tecnica incluyen recibir corrientes RTP de audio y video y asignando una trama completa de datos de video RTP a paquetes de canal de comunicacion que ocupan el mismo periodo o menor, como la velocidad de trama de video, tambien se asigna una trama completa de datos de audio RTP a paquetes de canal de comunicacion que ocupan el mismo periodo o menor, como la velocidad de trama de audio; los paquetes de canal de comunicacion de audio y video se transmiten simultaneamente; la recepcion y asignacion de corrientes RTP se pueden llevar a cabo en una estacion remota o estacion base.

    Abstract: An apparatus for testing user interface integrity of speech-enabled devices includes a processor and a storage medium coupled to the processor. A set of voiced utterances is stored in the storage medium. A software module is executed by the processor to determine a state of the voice recognizer and provide a response to the voice recognizer in accordance with the determined state. The response may be to produce at least one voiced utterance in accordance with the state. The apparatus may be acoustically coupled to the voice recognizer. The apparatus may also, or in the alternative, be electrically coupled by a cable to the voice recognizer. The set of voiced utterances may include multiple sets of voiced utterances, each set having been spoken by a different person. The set of voiced utterances may also, or in the alternative, include multiple sets of voiced utterances, each set of voiced utterances having been spoken under different background noise conditions. The software module may also be executable to monitor the performance of the voice recognizer.
