    Abstract: Methods and systems are provided for enhancing listening intelligibility in electronic devices. A vibration sensor may be used to generate feedback corresponding to vibrations caused by the outputting of the acoustic signals, and the feedback may be used in adjusting the listening intelligibility stage. In some instances, a microphone may be used to obtain audio input corresponding to ambient noise affecting intelligibility of audio outputted, as acoustic signals, via a speaker, to a user. The audio input may be used to control a listening intelligibility stage applied to audio content when the acoustic signals are generated for outputting by the speaker. In particular, the listening intelligibility stage may comprise application of dynamic time-scale modifications.

    Abstract: This disclosure provides methods, devices, and systems for videoconferencing. The present implementations more specifically relate to audio signal processing techniques that can be used to identify speakers in a videoconference. In some aspects, an audio signal processor may map each speaker in a videoconference to a respective spatial direction and transform the audio signals received from each speaker using one or more transfer functions associated with the spatial direction to which the speaker is mapped. The audio signal processor may further transmit the transformed audio signals to an audio output device that emits sounds waves having a directionality associated with the transformation. For example, the audio signal processor may apply one or more head-related transfer functions to the audio signals received from a particular speaker so that the sound waves emitted by the audio output device are perceived as originating from the spatial direction to which the speaker is mapped.

    Abstract: A first mobile communication device that includes a first microphone, a first speaker, and a first delay unit. The first microphone is configured to (i) receive, during a conference call, a first user first microphone signal from a first user, and (ii) output a first microphone digital signal to the first delay unit. The first user first microphone signal represents audio content outputted by the first user. The first delay unit is configured to delay, by a delay period, the first microphone digital signal to provide a delayed first user first device digital signal. The first mobile communication device is configured to output, to a mixer, the delayed first user first device digital signal. The delay period is determined based on measurements executed by at least one mobile communication device out of the first mobile communication device, a second mobile communication device and a third mobile communication device.
