Abstract: Various embodiments describe a multi-step process for determining whether the keyword has been spoken. The first tier uses an onboard digital signal processor (DSP) to process converted audio signals. If the DSP analysis cannot confirm the keyword due to noise in the signal, a second tier of processing may use an applications processor (AP) and a more stringent audio filter to try to verify the keyword. If the AP analysis cannot confirm the keyword, a third tier of processing may use server side processor and an even more stringent audio filter to try to verify the keyword. Certain signal to noise ratios (SNRs) of the detected and converted audio signal are used to decide when and if to try the second and third tier of processing.

Abstract: Examples are disclosed for placing an outbound telephony call using a mobile telephony device as a proxy to make the call on behalf of a smart speaker device. At a communications server, it is determined whether a mobile telephony device is in proximity of a smart speaker device. When the mobile telephony device is in proximity of a smart speaker device and attempts to place a telephony call, the communications server establishes a communications link between the communications server and the smart speaker device. The communications server may then dial the telephone number sent by the mobile telephony device and establish a communications link between the communications server and a device associated with the dialed telephone number.

Abstract: Various embodiments are directed to techniques for enhanced call routing for groups. Some embodiments are particularly directed to a connection manager that can identify one or more secondary telephony endpoints to invite to join a call based on one or more routing policies. One or more embodiments described herein may include a connection manager that provides customizable extension capabilities to a wireless cellular phone. The systems, devices, and methods described herein may be embodied in and performed by communication devices, telecommunications servers, and other devices, and software instructions executed by some or all of such devices.

Abstract: Disclosed are techniques for mediating a communication session between a communication device operating asynchronously and a communication device operating synchronously. A communications server receives a first set of audio data segments transmitted asynchronously from an asynchronous communication device over a first communication link and converts the audio data segments into a first synchronous stream of audio data. The communications server then establishes a synchronous audio media channel between itself and the synchronous device over a second communication link before transmitting the first synchronous stream of audio data to the second communication device over the established synchronous audio media channel. The communications server may also receive a second synchronous stream of audio data from the synchronous communication device and convert the second synchronous stream of audio data into a second set of audio data segments.

Abstract: Examples are disclosed for responding to voice commands within an existing telephony call between two or more end user communication devices mediated by an IP based communications server. The server is mediating a telephony call among the two or more end user communication devices where each end user communication device has its own communication link to the server. The server may detect a trigger event from one of the end user communication devices. Upon detecting the trigger event, the server may receive voice input over the communication link from the end user communication device that generated the trigger event. The received voice input may be parsed into one or more voice commands. The server may then cause the one or more voice commands to be executed. In other embodiments, much of the intelligence and processing may be carried out on the end user communication device directly.

Abstract: Various embodiments are generally directed to techniques for transaction processing in servers. Some embodiments are particularly directed to a transaction processing system that is able to induce random bounded delay in processing transactions at a server. In some embodiments, the transaction processing system may monitor a rate of transaction requests received at a server and determine whether to delay servicing at least one requested transaction based on comparing the rate of transaction requests received, or a value at least partially based thereon, to one or more thresholds.
