A call system includes a terminal apparatus capable of inputting and outputting call audio and a server apparatus configured to relay transmission and reception of audio information including the call audio between the terminal apparatus and another terminal apparatus. The server apparatus or the terminal apparatus performs an adjustment process to adjust the audio information so as to increase a volume of the call audio that is inputted to and outputted from the terminal apparatus according to a volume of call audio inputted at the terminal apparatus or a distance from the terminal apparatus to a user.

The invention concerns a mobile terminal with at least two transducers (LSm, LSs1, LSS2) used simultaneously as loudspeakers for stereophonic effect. According to the invention, one of said transducers is a main transducer (LSm) with a main working frequency band (Bm) corresponding to at least the phone frequency band, while the other transducer is a secondary transducer (LSs1; LSs2) with a secondary working frequency band (Bs1; Bs2) band different from said main frequency band, the lowest frequencies of said secondary working frequency band (Bs1; Bs2) being greater than the lowest frequencies of said main working frequency band.

An electronic device is provided that includes a wireless communication device configured to connect with wireless external devices. The electronic device obtains information regarding the wireless external devices. Before and after a call connection event, it is determined whether each of the wireless external devices includes a microphone based on the information. In response to receiving the call connection event, when it is determined that only one of the wireless external devices includes a microphone, an audio input is obtained from the one of the wireless external devices that includes the microphone. In response to receiving the call connection event, when it is determined that at least two of the wireless external devices each include a respective microphone, an audio input is selectively obtained from a microphone of one of the at least two of the plurality of wireless external devices.

A reminder method and apparatus and an electronic device. When a difference between a voice volume of a user in conversation and a reference volume is greater than a preset threshold, output of reminder to the user is controlled. Thus, the user may be reminded when his/her conversation is too loud for the surrounding environment automatically according to a comparing result of the voice volume of the user in conversation and the reference volume, and user experience may be improved.

A method includes outputting, by a computing device, to a remote computing device, test audio data; determining, by the computing device, whether audio data detected by an audio input device includes the test audio data; and responsive to determining that the test audio data was not detected by the audio input device, temporarily refraining, by the computing device, from outputting advisory audio data indicating the audio input device is ready to receive a spoken audio command.

The communication device comprising a communication implementer, a TV program implementer, and a multiple language implementer.

A conferencing endpoint includes a loudspeaker component, a base microphone, and an adaptive volume control module which evaluates near-end audio conditions at a conferencing endpoint and automatically determines whether to change the audio volume at a near-end loudspeaker. The endpoint can, for example, detect that a person speaking into the base microphone has begun to speak more loudly to compensate for nearby background noise. The endpoint can automatically adjust the loudspeaker volume or provide an alert that the loudspeaker will be changed, giving the user the opportunity to accept or decline an increase in speaker volume.

An audio signal outputting method includes: in a case where a first audio signal is output through a first device, receiving a first input of a user that is used to trigger a terminal device to output a second audio signal; and in response to the first input, outputting the first audio signal through a second device, and outputting a second audio signal through a third device. The first audio signal and the second audio signal are audio signals generated by different applications in the terminal device. The first device is any one of the terminal device and the at least one audio device, and the second device and the third device are any two of the terminal device and the at least one audio device.

A smartphone displays a user interface that simultaneously shows a first image that when selected by a listener plays sound as stereo audio to a listener wearing headphones or the earphones, a second image that when selected by the listener plays the sound as spatial audio through the headphones or the earphones, and an image of a head of a person.

A method expedites processing and playing of binaural sound during an electronic communication between a first user and a second user. An electronic device of the first user convolves sound into binaural sound for the second user before the binaural sound transmits to the electronic device of the second user. In this way, the binaural sound is already convolved and ready to play upon receipt at the electronic device of the second user.
