Example techniques relate to local voice control in a media playback system. A satellite device (e.g., a playback device or microcontroller unit) may be configured to recognize a local set of keywords in voice inputs including context specific keywords (e.g., for controlling an associated smart device) as well as keywords corresponding to a subset of media playback commands for controlling playback devices in the media playback system. The satellite device may fall back to a hub device (e.g., a playback device) configured to recognize a more extensive set of keywords. In some examples, either device may fall back to the cloud for processing of other voice inputs.

A system for limiting vehicle operation is disclosed. The system may comprise one or more memory units for storing instructions and one or more processors configured to execute the instructions to perform operations. The operations may comprise determining that a key device is inside the vehicle; performing an authentication; setting the vehicle in a first vehicle mode; starting the vehicle based on the determination and the first authentication; and limiting vehicle operation based on the first vehicle mode.

A computing system facilities live and robo-advising sessions, and transitions therebetween based on detection of triggers. The computing system may extract voice inputs of a user from ambient sounds captured using a sound sensor. Based on an analysis of the voice inputs and detection of corresponding triggers, the computing system may initiate a robo-advising session, or a live communication session between a user computing device and an advisor computing device. Detection of another trigger during the robo-advising session or the live communication session may lead to a transition to a live communication session or a robo-advising session, respectively.

Provided a method performed by an automatic interpretation server based on a zero user interface (UI), which communicates with a plurality of terminal devices having a microphone function, a speaker function, a communication function, and a wearable function. The method includes connecting terminal devices disposed within a designated automatic interpretation zone, receiving a voice signal of a first user from a first terminal device among the terminal devices within the automatic interpretation zone, matching a plurality of users placed within a speech-receivable distance of the first terminal device, and performing automatic interpretation on the voice signal and transmitting results of the automatic interpretation to a second terminal device of at least one second user corresponding to a result of the matching.
