A voice conversation apparatus includes a microphone configured to convert a voice of the one speaking person into a voice signal, modulation means configured to modulate the voice signal into a signal using ultrasound as a carrier wave, sound wave emission means configured to emit the signal modulated by the modulation means as a sound wave using ultrasound as a carrier wave, alignment means used by the one speaking person to make alignment so that the sound wave emission means is oriented to another voice conversation apparatus, pairing means configured to perform a pairing process of connecting the voice conversation apparatus to the other voice conversation apparatus by near-field communication, and control means configured to receive an instruction to start a conversation from the one speaking person and to, when the pairing process is successful, cause the sound wave emission means to emit the sound wave.

The overall performance of an ANC system may be improved by configuring the ANC system to perform adaption in the frequency domain. The ANC systems may be configured to update an algorithm of an adaptive filter based, at least in part, on the first input signal, the second input signal, and a feedback signal that is based on an output of the adaptive filter. Updating may include changing parameters of the algorithm based on a SDR based, at least in part, on the first input signal. Updating may also include normalizing a step size and processing at least full band information for the input signal in a frequency domain to generate coefficient values for the algorithm. Updating may also include applying a frequency domain magnitude constraint on adaptive filter coefficients.

Systems and methods are provided for operating a pair of earbuds based whether the earbuds are being worn by the same user or different users. In this regard, one or more processors may determine, based on sensor signals from the pair of earbuds, whether the pair of earbuds are being worn by a same user or different users. Based on determining that the pair of earbuds are being worn by the same user, the pair of earbuds may be operated in a first mode so that one or more functions are controlled based on a first set of input settings. Based on determining that the pair of earbuds are being worn by different users, the pair of earbuds may be operated in a second mode so that the one or more functions of the pair of earbuds are controlled based on a second set of input settings.

The virtual phone further includes a configuration of a user-specific handheld device that is derived from the user-specific handheld device is stored in a memory that is accessible to the processor; wherein the virtual phone presents a visual representation of the user-specific handheld device on the touch screen based on the configuration.

A method including: transmitting, by a control device, a first portion of content comprising a first portion of a signal corresponding to a multimedia presentation characteristic of a peripheral device; receiving, when an adjustment of the signal is below an adjustment threshold, a first instance of an input indicating a request to change the multimedia presentation characteristic; in response to receiving the first instance of the input, adjusting a second portion of the signal and transmitting a second portion of the content comprising the adjusted second portion of the signal; receiving, when the adjustment of the signal is at or above the adjustment threshold, a second instance of the input; and transmitting, in response to receiving the second instance of the input, a communication signal to the peripheral device to adjust a peripheral device control of an output of the multimedia presentation characteristic.

Embodiments of this application disclose a call method and an apparatus. In the call method, when a user does not actively select an audio device as a voice pickup device and a voice play device, after establishing a call connection to another electronic device, an electronic device selects, from available audio devices, an audio device that meets a user expectation as the voice pickup device and the voice play device. According to technical solutions provided in the embodiments of this application, user experience in a call process can be improved.

This specification describes an apparatus for controlling audio output. The apparatus provides first and a second audio components for output to first and second audio transducers of a wearable device, determine a proximity between the wearable device and a third audio transducer and determining a first or second state of the first and second audio transducers, and controlling output of at least one of the first and second audio components based on the determined proximity and the state of the first and second transducers. Responsive the proximity being under a threshold and the state of the first transducer being in a first state whilst the second transducer is in a second state, the apparatus causes output of the audio component associated with the second state transducer to be transferred to the third audio transducer whilst continuing to output the audio component associated with the first state transducer to said transducer.

A head-worn audio device is provided with a circuit for voice signal enhancement. The circuit comprises at least a plurality of microphones, arranged at predefined positions, where each microphone provides a microphone signal. The circuit further comprises a directivity pre-processor and a blind source separation processor. The directivity pre-processor is connected with the plurality of microphones to receive the microphone signals and being configured to provide at least a voice signal and a noise signal. Directivity pre-processing increases the mutual independence of the signals provided to the blind source separation processor and thus improves processing by blind source separation. The blind source separation processor receives at least the voice signal and the noise signal, and is configured to conduct blind source separation on at least the voice signal and the noise signal to provide at least an enhanced voice signal with reduced noise components.
