Devices such as smartphones, smart speakers, etc. provide spoken responses to user queries using Text-To-Speech (TTS) technologies that convert textual information to spoken audio. In some cases, the volume at which the audio response is delivered by the device can be unsuitable, e.g., too soft or too loud for the user’s environment. This disclosure describes techniques to automatically adjust the volume of audio responses based on contextual information, obtained with the user’s permission. If the user permits, the volume level of the response is determined based on the distance of the user from the device and characteristics of the user’s environment, e.g., ambient noise.
