A system, method, and computer-readable medium are disclosed for improved threat sensitivity in a gaming application. As audio streams are received during a gaming scenario, a threat profile is selected that best matches the audio streams. The threat profile is a machine language cluster of noise used to adjust speaker equalization profile to emphasize threat noises. Digital signal processing (DSP) coefficients of the speaker equalization profile are adjusted as the gaming application continues.

The present disclosure provides various embodiments of methods for intelligent active speaker identification and information handling systems (IHSs) utilizing such methods. In general, the methods disclosed herein may be used to accurately identify an active speaker in a communication session with an application or an IHS, regardless of whether the active speaker is alone, in a group environment, or using someone else's system or login to participate in the communication session. The methods disclosed herein may use voice processing technology and one or more voice identification databases (VIDs) to identify the active speaker in a communication session. In some embodiments, the disclosed methods may display the identity of the active speaker to other users or participants in the same communication session. In other embodiments, the disclosed methods may dynamically switch between user profiles or accounts during the communication session based on the identity of the active speaker.

Information handling systems and methods for accurately identifying an active speaker in a communication session

An orchestrator associated with a collaboration application client executed by a near end device dynamically adapts volume level and/or other audio quality parameters to deliver a consistent voice experience to a collaboration participant. The orchestrator is informed by multiple machine learning engines collecting and analyzing inputs from one or more existing sensor-based functions embedded in the near end device. The orchestrator determine an audio configuration of the device and audio preferences of the user. Identities of far end participants are determined and their profiles are mapped against the user volume preferences. The orchestrator functions as an informing agent to the audio signal processing engine of the device, managing speaker output volume and microphone gain settings, based upon the machine learning engines and the sensor-based functions. The sensor based functions may detect proximity, head pose, gaze point, eye position, facial identities, mood, and so forth.
