In an interaction between a virtual assistant and a user, it is often the case that the responses of the virtual assistant arrive just after the passage of critical events in the user’s timeline. For example, navigational instructions to exit a freeway sometimes arrive just a bit too late to take the off-ramp. Some of this latency is attributable to the very nature of spoken audio playback: spoken audio playback being a linear medium, the length of time required for the spoken content to play can affect the accuracy of time-sensitive actions. This disclosure describes techniques that take into account the length of a response to be provided to the user such that the response is delivered in a timely manner with sufficient allowance for reaction time.
