Abstract: Content is received at a receiving equipment from a transmitting user terminal over a network in a communication session between a transmitting user and a receiving user. The received content comprises audio data representing speech spoken by a voice of the transmitting user, and further comprises text data generated from speech spoken by the voice of the transmitting user during the communication session. At the receiving equipment, at least a portion of the received text data is converted to artificially-generated audible speech based on a model of the transmitting user's voice stored at the receiving equipment (and in embodiments in dependence on the receive audio quality). The received audio data and the artificially-generated speech are supplied to be played out to the receiving user through one or more speakers.

Abstract: Schematized data roaming is described herein. In one or more implementations, a cloud service includes a cloud data store that is configured to store schematized data comprising user preferences and settings of client devices associated with a user profile. The schematized data includes a schema that is shared across the client devices and globally defined by the cloud service which enables the user preferences and setting to be re-used across multiple devices and device classes, including devices that the user has not previously interacted with before. The schematized data includes attributes, for each schematized data structure, which provide rules for processing or storing the corresponding schematized data structure in the cloud data store. Such attributes may include a conflict resolution policy, an upload policy, or a partition policy.

Abstract: An apparatus includes microphone receivers configured to receive microphone signals from a plurality of microphones. A comparator configured to determine a speech similarity indication indicative of a similarity between the microphone signal and non-reverberant speech for each microphone signal. The determination is in response to a comparison of a property derived from the microphone signal to a reference property for non-reverberant speech. In some embodiments, the comparator is configured to determine the similarity indication by comparing to reference properties for speech samples of a set of non-reverberant speech samples. A generator is configured to generate a speech signal by combining the microphone signals in response to the similarity indications. The apparatus may be distributed over a plurality of devices each containing a microphone, and the approach may determine the most suited microphone for generating the speech signal.

Abstract: A noise attenuation apparatus receives an audio signal comprising a desired and a noise signal component. Two codebooks (109, 111) comprise respectively desired signal candidates representing a possible desired signal component and noise signal contribution candidates representing possible noise contributions. A segmenter (103) segments the audio signal into time segments and for each time segment a noise attenuator (105) generates estimated signal candidates by for each of the desired signal candidates generating an estimated signal candidate as a combination of a scaled version of the desired signal candidate and a weighted combination of the noise signal contribution candidates. The noise attenuator (105) minimizes a cost function indicative of a difference between the estimated signal candidate and the audio signal in the time segment. A signal candidate is then determined for the time segment from the estimated signal candidates and the audio signal is noise compensated based on this signal candidate.

Abstract: A processing system includes a plurality of processor cores and a plurality of private caches. Each private cache is associated with a corresponding processor core of the plurality of processor cores and includes a corresponding first set of cachelines. The processing system further includes a shared cache shared by the plurality of processor cores. The shared cache includes a second set of cachelines, and a shadow tag memory including a plurality of entries, each entry storing state information for a corresponding cacheline of the first set of cachelines of one of the private caches.

Abstract: A processor replaces data at a first cache based on hints from a second cache, wherein the hints indicate information about the data that is not available to the first cache directly. When data at an entry is transferred from the first cache to the second cache, the first cache can provide an age hint to the second cache to indicate that the data should be assigned a higher or lower initial age relative to a nominal initial age. The second cache assigns the entry for the data an initial age based on the age hint and, when replacing data, selects data for replacement based on the age of each entry.

Abstract: A sensor such as a presence sensor for use in a lighting system or other system that adapts to information from a plurality of active presence sensors.

The disclosure presents protocols for coordinating transmissions in active sensing systems. The invention may be applied to various active modalities (e.g. ultrasound, RF), for example that find applications in indoor and outdoor lighting controls.

Using the photon count, an image processing unit of the imaging apparatus generates a 2D or 3D tomographic image of the borehole.

Abstract: An audio stream is encoded for transmission to a receiving device via a communications channel. The to-be transmitted audio stream is received at an audio encoder executed on a processor. The processor has an amount of available processing resources. An available bandwidth of the communications channel is determined. Based on the determined bandwidth, a portion of the available processing resources is allocated to the audio encoder. The allocated portion is greater if the determined bandwidth is below a bandwidth threshold. The audio encoder encodes the audio stream using the allocated portion of processing resources, and transmits the encoded audio stream to the receiving device via the communications channel.
