Abstract: Embodiments include methods of voice or speech recognition in varied environments and/or user emotional states executed by a processor of a computing device. The processor of a computing device may determine a voice or speech recognition threshold for voice or speech recognition based on information obtained from contextual information detected in an environment from which a received audio input was captured by the computing device and an emotional classification of a user's voice in the received audio input. The processor may determine a confidence score for one or more key words identified in the received audio input. The processor may then output results of a voice or speech recognition analysis of the received audio input in response to the determined confidence score exceeding the determined voice or speech recognition threshold.
