Abstract

The present disclosure relates generally to speech processing. Humans change their speech patterns in noisy environments. The systems and devices described herein can compensate for noisy environments to be more human-like. Thus, the configurations and implementations herein can determine a sound profile for the sound environment where the user is listening. Based on the sound profile, the devices can determine a transform to apply to output speech from the device. This transform is applied to the wake word, speech recognition, and to the output speech to compensate for the noise level of the environment by mimicking the Lombard effect.
