Abstract: Audio data that encodes an utterance of a user is received. It is determined that the user has been classified as a novice user of a speech recognizer. A speech recognizer setting is selected that is used by the speech recognizer in generating a transcription of the utterance. The selected speech recognizer setting is different than a default speech recognizer setting that is used by the speech recognizer in generating transcriptions of utterances of users that are not classified as novice users. The selected speech recognizer setting results in increased speech recognition accuracy in comparison with the default setting. A transcription of the utterance is obtained that is generated by the speech recognizer using the selected setting.

Abstract: An in-wall speaker system having at least one pair of active transducers mounted in a wall section. The active transducers may be mounted in at least one enclosure. Each active transducer has a sound radiating surface. Each active transducer is also mounted substantially perpendicular to a surface of the wall section with the sound radiating surfaces substantially parallel to each other. The sound radiating surfaces may be facing each other or away from each other. The in-wall speaker system may also include one or more pairs of passive radiators to generate sound from sound pressure generated by the active transducers. The pairs of speakers in the wall section may be mounted vertically or horizontally within the wall, with a slot or a vent at the opening at the space between the speaker pairs.

Abstract: A capacitive micro-machined ultrasonic transducer (CMUT) array includes an improved elementary aperture for imaging operations. The transducer can be of a linear, curved linear, annular, matrix or even single surface configuration. The elementary apertures thereof are formed by a specific arrangement of capacitive micromachined membranes (CMM) so as to exhibit ideal acoustical and electrical behavior when operated with imaging systems. The CMM arrangements can be either conventional where the element transducers of the array are uniformly shaped by predefined CMMs in a manner such as to exhibit acoustic behavior similar to a piezoelectric transducer, or can be more sophisticated, wherein each element transducer is formed by a specific combination of different CMMs (i.e., of a different size and/or shape) so as to provide the transducer with built-in acoustic apodization that can be implemented in the azimuth and/or elevation dimension of the device.

Abstract: A motorized scanhead device is capable of rotating an array transducer through 360 degrees of angular rotation in a manner such as to provide acquisition of images in successive scanning planes arranged around the principal axis of the device. The device can be incorporated in endoscopes (e.g., transesophageal endoscopes), laparoscopes, endocavity or intracavity probes so as to provide an expanded angle of vision or to render 3D images, without the need for external movement of the device. The motorized scanhead device includes a motor that is isolated from the transducer signal interconnections in order to minimize electrical discharges associated with motor operation and to provide more room between an associated probe housing and the scanhead device.
