Abstract: The various implementations described herein include methods, devices, and systems for recognizing speech, such as user commands. In one aspect, a method includes: (1) receiving audio input data via the one or more microphones; (2) generating a plurality of energy channels for the audio input data; (3) generating a feature vector by performing a per-channel normalization to each channel of the plurality of energy channels; and (4) obtaining recognized speech from the audio input utilizing the feature vector.

Abstract: Disclosed herein are systems and methods for a sound enhancement system coupled to a mobile device. In one aspect, the present disclosure includes the system having first bidirectional communication link configured to receive an audio signal, transmit an audio signal, and receive configuration parameters. The system also includes a memory configured to store the configuration parameters. Additionally, the system has an audio input configured to receive ambient audio. Yet further, the is configured to operate in one of two operation modes. In the first mode, the system is configured to receive an audio signal from the bidirectional communication link and output an audio signal based on the received audio signal by way of the audio output pathway, and in the second mode, the system is configured to process the ambient audio signal by the audio processor based on stored configuration parameters and create an output audio signal.
