Abstract: Method for performing speech enhancement using a Deep Neural Network (DNN)-based signal starts with training DNN offline by exciting a microphone using target training signal that includes signal approximation of clean speech. Loudspeaker is driven with a reference signal and outputs loudspeaker signal. Microphone then generates microphone signal based on at least one of: near-end speaker signal, ambient noise signal, or loudspeaker signal. Acoustic-echo-canceller (AEC) generates AEC echo-cancelled signal based on reference signal and microphone signal. Loudspeaker signal estimator generates estimated loudspeaker signal based on microphone signal and AEC echo-cancelled signal. DNN receives microphone signal, reference signal, AEC echo-cancelled signal, and estimated loudspeaker signal and generates a speech reference signal that includes signal statistics for residual echo or for noise.

Abstract: An audio system has a housing in which are integrated a number of microphones. A programmed processor accesses the microphone signals and produces a number of acoustic pick up beams based groups of microphones, an estimation of voice activity and an estimation of noise characteristics on each beam. Two or more beams including a voice beam that is used to pick up a desired voice and a noise beam that is used to provide information to estimate ambient noise are adaptively selected from among the plurality of beams, based on thresholds for voice separation and thresholds for noise-matching. Other embodiments are also described and claimed.

Abstract: An orientation detector can have a first microphone, a second microphone, and a reference microphone spaced from the first microphone and the second microphone. An orientation processor can be configured to determine an orientation of the first microphone, the second microphone, or both, relative to a user's mouth based on a comparison of a relative strength of a first signal associated with the first microphone to a relative strength of a second signal associated with the second microphone. A channel selector in a speech enhancer can select one signal from among several signals based at least in part on the orientation determined by the orientation processor. A mobile communication handset can include a microphone-based orientation detector of the type disclosed herein.

Abstract: A toothbrush has one or two part-spherical pockets formed in the brush surface. Balls or pellets of matching shape of dehydrated toothpaste are placed in the depressions, the brush is wetted and the pellets turn to a gel, ready for brushing. The pellets may be of various colors and flavors to entice children to brush their teeth and may be dispensed from a storage chamber carried in the tooth brush handle.

Abstract: A personal hygiene brush which includes a furcated end comprising cleaning heads from which bristles radiate about the outer perimeter and a non-furcated end including an additional cleaning head from which bristles radiate about the outer perimeter. The personal hygiene brush is capable of cleaning of all types of piercings, intra and extra-orally, as well as dental implants and implant supported prosthesis. The personal hygiene brush enables the user to clean around, under and through their individual ornamental body rings and rods without removing them from the body parts to which they are attached.
