摘要： Some implementations of the disclosure relate to a non-transitory computer-readable medium having executable instructions stored thereon that, when executed by a processor, cause a system to perform operations comprising: obtaining a first energy-based target for audio; obtaining a first version of a sound mix including one or more audio components; computing, for each audio frame of multiple audio frames of each of the one or more audio components, a first audio feature measurement value; optimizing, based at least on the first energy-based target and the first audio feature measurement values, gain values of the audio frames; and after optimizing the gain values, applying the gain values to the first version of sound mix to obtain a second version of the sound mix.

摘要： A computer-implemented method includes receiving audio packets associated with a first client device, where the audio packets each include an audio capture waveform, a timestamp, and a digital entity identification (ID). The method further includes determining, based on the digital entity ID, a position of a first digital entity in a metaverse. The method further includes determining a subset of other digital entities in a metaverse that are within an audio area of the first digital entity based on (a) a falloff distance between the first digital entity and each of the other digital entities and (b) a direction of audio propagation between the first digital entity and each of the other digital entities. The method further includes transmitting the audio packets to second client devices associated with the subset of other digital entities in the metaverse.

摘要： Systems and methods are provided for analyzing voice-based audio inputs. A voice-based audio input associated with a user (e.g., wherein the voice-based audio input is a prompt or a command) is received and measures of one or more features are extracted. One or more parameters are calculated based on the measures of the one or more features. The occurrence of one or more mistriggers is identified by inputting the one or more parameters into a predictive model. Further, systems and methods are provided for identifying human mental health states using mobile device data. Mobile device data (including sensor data) associated with a mobile device corresponding to a user is received. Measurements are derived from the mobile device data and input into a predictive model. The predictive model is executed and outputs probability values of one or more symptoms associated with the user.

摘要： A method includes obtaining, by a processor, an audio echo signal and an audio desired signal from an acoustic echo correction stage of an electronic device, and converting the echo signal and the desired signal to the frequency domain. The method further includes grouping, by the processor, frequency bin results of respective frequency domain converted echo and desired signals into respective echo and desired sub-bands. A sub-band suppressor gain is estimated based on an estimated sub-band energy for the echo and desired sub-bands. The method further includes modulating the frequency domain converted desired signal to compensate for residual echo, the modulating based, at least in part, on the estimated sub-band suppressor gain, and the modulating producing a compensated frequency domain converted echo signal. The method also includes converting the compensated frequency domain converted desired signal into time domain converted audio output signal.

摘要： There is provided a signal processing apparatus for amplifying or attenuating, with respect to a signal in which a desired signal and another signal are mixed, the desired signal and the other signal at different ratios. The signal processing apparatus includes a separator that obtains an estimated first signal and an estimated second signal by receiving a mixed signal in which a first signal (for example, speech) and a second signal (for example, noise) are mixed and estimating the first signal and the second signal. Furthermore, the signal processing apparatus includes a gain adjuster that obtains a gain-adjusted mixed signal by receiving the estimated first signal and the estimated second signal.

摘要： A noise suppression device includes: an adaptive filter unit that suppresses, using an adaptive filter, a noise component contained in a voice signal generated from a voice captured by a voice input unit to generate a corrected voice signal; a noise generation detection unit that detects timing of generation of the noise component in the voice signal; and a period suppression unit that suppresses the corrected voice signal during a predetermined period of time after the timing of the generation of the noise component.

摘要： 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.

摘要： A portable terminal has a network interface that receives a set of instructions having a sequence of at least one location and audio properties associated with the at least one location from a server. An audio circuit receives audio signals picked up by a microphone and processes the audio signals in a manner defined by the audio properties associated with the at least one location. A speech recognition module receives processed signals from the audio circuit and carries out a speech recognition process thereupon.
