Initiation of real-time media processing in response to a trigger event
Calls between a customer and an agent often require additional processing of the media in real time. Processing every call in such a manner is often unnecessary and the results deleted or ignored, or prohibited due to a policy for certain calls. Knowing if a call should be processed may be determined too late for the media to be forked. While the customer and agent may engage in the call as a peer-to-peer connection, additional processing requires holding the initial invite long enough, such as with a preservation message, that a session boarder controller may fork the call for subsequent processing without timing out. |

Some embodiments provide a method for performing deep packet inspection (DPI) for an SD-WAN (software defined, wide area network) established for an entity by a plurality of edge nodes and a set of one or more cloud gateways.

Field-controlled sensor architecture and related methods
A nanoelectric field effect sensor uses the field created by the surface charge profile of biomolecular binding to modulate the current flowing between a source and a drain. We have shown that a patterned side or top gate can be used to calibrate the biomolecular field modulation. This approach provides an electrical sensitivity characterization of the sensor before exposing it to sample fluid. Furthermore, a side gate or a top gate voltage with the right sign can be used to control the binding event during functionalization or sensing. For instance, a negative gate voltage can prevent binding of negatively charged proteins on a sensor. This approach of electric-field control of binding can be used in a differential sensor configuration as well. For instance, in a two-sensor single-bridge technique, one of the sensors can be exposed to a local electric field to prevent binding events, which can then be used for background cancellation in a second sensor, not exposed to the electric field. Furthermore, this approach can be used to prepare a sensor chip for multiplexing, where different chip areas can be turned on or off by applying local electric fields. |

Self-voice adaptation
Aspects of the subject technology relate to a device including a microphone, a filter and a processor. The filter receives an audio signal including ambient noise and a voice of a user of the device from the microphone. At least a portion of ambient noise is filtered from the audio signal. The processor determines a level of the ambient noise in the received audio signal and dynamically adjusts a gain applied to the filtered audio signal based on the level of the ambient noise. |

Context-based speech enhancement
A device to perform speech enhancement includes one or more processors configured to obtain input spectral data based on an input signal. The input signal represents sound that includes speech. The one or more processors are also configured to process, using a multi-encoder transformer, the input spectral data and context data to generate output spectral data that represents a speech enhanced version of the input signal. |

Signal enhancement and noise reduction with binaural cue preservation control based on interaural coherence
An audio signal is enhanced using interaural coherence to control noise reduction and binaural cue preservation. Sounds from a local area are detected via an acoustic array. An interaural coherence is determined using the detected sounds. Sound filters for an audio signal are generated based on the interaural coherence. The sound filters implement a tradeoff between increasing signal-to-noise ratio (SNR) between a target source and an interfering source and preserving of binaural information of the interfering source. The tradeoff is controlled based on the interaural coherence. The sound filters are applied to the audio signal to generate audio content. The audio content is presented via a speaker array. |

Systems and methods for pervasive advisor for major expenditures
A pervasive advisor for major purchases and other expenditures may detect that a customer is contemplating a major purchase (e.g., through active listening). The advisor may assist the customer with the timing and manner of making the purchase in a way that is financially sensible in view of the customer's financial situation. A customer may be provided with dynamically-updated information in response to recent actions that may affect an approved loan amount and/or interest rate. Underwriting of a loan may be triggered based on the geo-location of the user. Financial advice may be provided to customers to help them meet their goals using information obtained from third party sources, such as purchase options based on particular goals. The pervasive advisor may thus intervene to assist with budgeting, financing, and timing of major expenditures based on the customer's location and on the customer's unique and changing circumstances. |

Methods and apparatus for improving search retrieval using inter-utterance context
A system and method of improving the Natural Language Understanding of a voice assistant.

Systems and methods for local interpretation of voice queries
Systems and methods are described herein for locally interpreting a voice query and for managing a storage size of data stored locally to support such local interpretation of voice queries. A voice query is received and compared with a plurality of stored voice queries having similar audio characteristics. If a match is identified, text corresponding to the matching stored voice query is retrieved, and an action corresponding to the retrieved text is performed. If the locally stored table does not contain a stored voice query that matches the voice query, the voice query is transmitted to a remote server for transcription. Once the transcription is received from the remote server, the voice query and the transcription are stored in the table in association with one another. |
