Abstract: A method and system for allowing a calling party to send a voicemail message as a text message are provided. A calling party leaves a voicemail message and that message is converted from voice to a text message. If the calling party wishes to confirm the conversion, the text message is then converted to a voicemail message. The converted voicemail message is presented to the calling party so that the calling party can review and edit the message. The calling party can review and edit any portion of the converted voicemail message. The edits of the voicemail message are applied and the voicemail message is converted to a new text message. If the calling party wishes to further review and edit the text message, it is converted to a new voicemail. Otherwise, the text message is sent to a called party.

Abstract: The system comprises audio headsets able to apply audio processing operations in response to presets that are common to all the headsets, smart terminals provided with audio flow generation means, and communication means to transmit to the headsets an audio flow and presets to be applied to this flow. A preset server memorises the presets associated with works. Certain terminals can generate presets and transmit them to the server, whereas other terminals collect these presets to apply them to the corresponding works at the time of reproducing these latter.

Abstract: Disclosed herein are systems, computer-implemented methods, and tangible computer-readable media for automatically transcribing voicemail. The method includes receiving a plurality of voicemail messages from callers, identifying for each voicemail message in the plurality of voicemail messages a first frequency with which the respective caller leaves voicemails, identifying for each voicemail message in the plurality of voicemail messages a second frequency with which a user requests transcription of each voicemail, assigning a priority ranking to each voicemail message in the plurality of voicemail messages based on the respective first frequency and the respective second frequency, and transcribing untranscribed voicemail messages with a highest priority ranking. The method can include establishing a priority ranking threshold and repeatedly transcribing a next highest ranking untranscribed voicemail message until no further untranscribed voicemail messages remain above the priority ranking threshold.

Abstract: In an example, time and frequency domain speech enhancement is implemented on a platform having a programmable device, such a PC or a smartphone running an OS. Echo cancellation is done first in time domain to cancel a dominant portion of the echo. Residual echo is cancelled jointly with noise reduction during a subsequent frequency domain stage. The time domain block uses a dual band, shorter length Adaptive Filter for faster convergence. Non-linear residual echo is cancelled based on an echo estimate and an error signal from the adaptive filters. A controller locates regions that had residual echo suppressed and which do not have speech and injects comfort noise. The controller can be full-duplex and operate non-linearly. An AGC selectively amplifies the frequency bins, based on the Gain function used by the residual echo and noise canceller.

Abstract: A MEMS acoustic transducer device has a capacitive microelectromechanical sensing structure and a biasing circuit. The biasing circuit includes a voltage-boosting circuit that supplies a boosted voltage on an output terminal, and a high-impedance insulating circuit element set between the output terminal and a terminal of the sensing structure, which defines a first high-impedance node associated with the insulating circuit element. The biasing circuit has: a pre-charge stage that generates a first pre-charge voltage on a first output thereof, as a function of, and distinct from, the boosted voltage; and a first switch element set between the first output and the first high-impedance node. The first switch element is operable for selectively connecting the first high-impedance node to the first output, during a phase of start-up of the biasing circuit, for biasing the first high-impedance node to the first pre-charge voltage.

Abstract: In one embodiment, a multimedia audio inserter removes the left and right audio channel data from a multimedia signal, for example an HDMI® signal and replaces it with an alternate audio signal, which may be the center channel audio signal provided by a digital surround sound receiver.

Abstract: In a method of reproducing audio signals using an electronic device, the electronic device decodes an audio file to generate original digital audio signals, and attenuates the original digital audio signals having frequencies that are lower than a preset cutoff frequency. The electronic device further amplifies each of attenuated digital audio signals and the original digital audio signals having frequencies that are higher than the preset cutoff frequency with a preset gain. Once the electronic device converts the amplified digital audio signals into analog audio signals, and outputs the analog audio signals to an audio amplifier, the audio amplifier amplifies the analog audio signals to drive a speaker to output the analog audio signals.
