Abstract
In some embodiments, a user device receives a voice signal corresponding to a user utterance. The user device may set a time marker corresponding to a point in time in the voice signal. The voice signal and the time marker may be transmitted to a server device. The server device may perform speech recognition using the voice signal. The server device may determine a time offset corresponding to a difference in time between an end point of the user utterance and a time associated with the time marker. The server device may determine a response to the user utterance. The server device may transmit the time offset and the response to the user device. The user device may use the time offset to determine a user-perceived latency between the end of the user utterance and a beginning of the response.
