Abstract: Methods and systems are provided for enhancing speech intelligibility in electronic devices. During outputting of acoustic signal via an electronic device, measurement of forces applied by user of the electronic device against the device (or enclosure thereof) may be obtained. The force measurements may be used to assess and/or estimate the listening intelligibility experienced by the user. Further, the force measurements may be used to control or adjust a listening intelligibility stage applied during generation and/or processing of the acoustic signals that are outputted via the electronic device. In some instances, an audio input, corresponding to ambient noise affecting intelligibility, may be obtained, and may be used to control or assist in controlling the listening intelligibility stage.

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: 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.
