This disclosure describes, in part, techniques for performing multi-path calculations for energy levels on an electronic device. For instance, the electronic device may include a first circuit and a second circuit, where the first circuit uses less power than the second circuit. As such, when operating in a standby mode, the electronic device may use the first circuit to calculate energy levels at the electronic device, such as speech-energy values and ambient-energy values. Additionally, while operating in an active mode, the electronic device may active the second circuit and then use the second circuit to calculate the energy levels at the electronic device. The first circuit and the second circuit can send/receive current energy levels between one another so that the electronic device can continually calculate the energy levels even when the electronic device switches between modes of operation.

Multi-path calculations for device energy levels

Apparatuses and systems for conserving power for a portable electronic device that monitors local audio for a wakeword are described herein. In a non-limiting embodiment, a portable electronic device may have two-phases. The first phase may be a first circuit that stores an audio input while determining whether human speech is present in the audio input. The second phase may be a second circuit that activates when the first circuit determines that human speech is present in the audio input. The second circuit may receive the audio input from the first circuit, store the audio input, and determine whether a wakeword is present within the audio input.

Hands free always on near field wakeword solution

Systems, methods, and computer-readable media are disclosed for remote configuration of battery charging settings. In one embodiment, an example device may include a battery, at least one memory that stores computer-executable instructions, and at least one processor. The at least one processor may be configured to access the at least one memory and execute the computer-executable instructions to determine that a charger is connected to the device, determine a first length of time that a maximum charging voltage for the battery has been set to a first voltage value, determine that the maximum charging voltage is to be reduced from the first voltage value to a second voltage value, and charge the battery at a maximum of the second voltage value.
