Abstract: A wireless device may output a first message or a compression context message. The first message may include (a) a first payload associated with a first RTP-SN, (b) the first RTP SN, and (c) a first PDCP SN that is incrementally synchronized with the first RTP SN. The compression context message may include an indicator of compression context between the first RTP SN and the first PDCP SN. The wireless device may obtain a confirmation that a compression context between the first RTP SN and the first PDCP SN is established at a receiver. In response, the wireless device may output a second message. The second message may have a second payload associated with a second RTP SN and a second PDCP SN that is incrementally synchronized with the second RTP SN. The second message does not comprise a ROHC header having an RTP SN field.

Abstract: A method includes receiving audio data that includes magnitude spectrum data descriptive of an audio signal. The method also includes providing the audio data as input to a neural network to generate an initial phase estimate for one or more samples of the audio signal. The method further includes determining, using a phase estimation algorithm, target phase data for the one or more samples of the audio signal based on the initial phase estimate and a magnitude spectrum of the one or more samples of the audio signal indicated by the magnitude spectrum data. The method also includes reconstructing the audio signal based on a target phase of the one or more samples of the audio signal indicated by the target phase data and based on the magnitude spectrum.

Abstract: A method and an apparatus for estimating speech signal in split-domain is disclosed. The method includes performing LP analysis on a noisy speech signal to generate a first plurality of LPC and a first residual signal. The method also includes estimating speech LPC spectrum to generate cleaned LPC. The method further includes estimating speech residual spectrum to generate cleaned residual signal. The method also includes synthesizing output signals based on the cleaned LPC and the cleaned residual signal.

Abstract: A device includes one or more processors configured to obtain data associated with a voice transmission during a communication session with a second device. The one or more processors are configured to analyze the data to generate a voice quality metric. The one or more processors are configured to, based on a determination that the voice quality metric fails to satisfy a voice quality threshold, generate an indication to a user that indicates a manner in which the user should proceed with the communication session.

Abstract: A device includes a memory and one or more processors coupled to the memory and configured to execute instructions from the memory. Execution of the instructions causes the one or more processors to combine two or more data portions to generate input data for a decoder network. A first data portion of the two or more data portions is based on a first encoding of a data sample by a multiple description coding network and content of a second data portion of the two or more data portions depends on whether data based on a second encoding of the data sample by the multiple description coding network is available. Execution of the instructions also causes the one or more processors to obtain, from the decoder network, output data based on the input data and to generate a representation of the data sample based on the output data.

Abstract: A device includes a memory configured to store one or more segments of time-series data. The device also includes one or more processors configured to generate, using a feature extractor, a latent-space representation of a segment of the time-series data. The one or more processors are also configured to provide one or more inputs to a classifier, the one or more inputs including at least one input based on the latent-space representation. The one or more processors are also configured to generate, based on output of the classifier, a processing control signal for the segment.

Abstract: Systems and techniques are described for coding audio signals. For example, a voice decoder can generate, using a neural network, an excitation signal for at least one sample of an audio signal based on one or more inputs to the neural network, the excitation signal being configured to excite a linear predictive coding (LPC) filter. The voice decoder can further generate, using the LPC filter based on the excitation signal, at least one sample of a reconstructed audio signal. For example, the neural network can generate coefficients for one or more linear time-varying filters (e.g., a linear time-varying harmonic filter and a linear time-varying noise filter). The voice decoder can use the one or more linear time-varying filters including the generated coefficients to generate the excitation signal.

Abstract: Systems and techniques are described for audio coding. An audio system receives feature(s) corresponding an audio signal, for example from an encoder and/or a speech synthesis engine. The audio system generates an excitation signal, such as a harmonic signal and/or a noise signal, based on the feature(s). The audio system uses a filterbank to generate band-specific signals from the excitation signal. The band-specific signals correspond to frequency bands. The audio system inputs the feature(s) into a machine learning (ML) filter estimator to generate parameter(s) associated with linear filter(s). The audio system inputs the feature(s) into a voicing estimator to generate gain value(s). The audio system generates an output audio signal based on modification of the band-specific signals, application of the linear filter(s) according to the parameter(s), and amplification using the gain amplifier(s) according to the gain value(s).
