Suspending voice guidance during route navigation

A system comprising:

• a processor;
• and
• a memory that stores computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising
• detecting a deviation from a route between an origin and a destination, the route being associated with a user device,
• obtaining contextual data associated with the user device, the contextual data comprising a geographic location and a vector associated with the user device,
• setting, based on the contextual data, a first value of a point-of-interest parameter that indicates whether the geographic location and the vector imply a visit to an expected stop,
• setting, based on the contextual data, a second value of a road-type parameter that indicates a type of a current road segment associated with the geographic location,
• determining that voice guidance should be suspended based on the first value and the second value;
• and
• sending, directed to the user device, a suspension command.

A computer storage medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

• detecting a deviation from a route between an origin and a destination, the route being associated with a user device;
• obtaining contextual data associated with the user device, the contextual data comprising a geographic location and a vector associated with the user device;
• setting, based on the contextual data, a first value of a point-of-interest parameter that indicates whether the geographic location and the vector imply a visit to an expected stop;
• setting, based on the contextual data, a second value of a route-distance parameter based on a distance between the geographic location and a nearest point along the route;
• determining that voice guidance should be suspended based on the first value and the second value;
• and
• sending, directed to the user device, a suspension command.
