Audible instructions Discussion View history

Revision as of 20:12, 15 November 2018 by Kartografer (talk | contribs) (added lead and sections on combined instructions and preposition choice)

When navigating in Waze with all sound turned on (rather than alerts only), Waze will issue various audible instructions at various times in order to prepare the user to make a certain movement. This page provides some information on their timing and format based on testing by Waze users. The testing was done using the Jane voice, but the basic principles should apply when using any other voice, except for the inclusion of street names if a voice has been selected that doesn't include them.

There are four possible audible instructions before a movement. Depending upon speed, distances, and timing, anywhere from one to four of these instructions may be heard.

Occurrence

We will call the different instructions A, B, C, and D based on the order they would appear. However, some instructions may not occur based on a number of conditions. The following is the order of the most common occurrence:

  • D
  • A, D
  • A, C, D
  • A, B, C, D

Details

Instruction A

Instruction A is given a few seconds after the previous movement (or, if the previous movement is onto a ramp, a few seconds after exiting the ramp(s) onto which the previous instruction brought you), unless you are so close to the next movement that there is not enough time to give both instruction A and D (in which case only instruction D is given).

Format depends on distance to next movement.

  • If distance to next movement > 4.35 mi (7.0 km), "Continue for (x hours and) y minutes to [street name]"
  • If distance to next movement < 4.35 mi (7.0 km), "In [distance], [instruction] [on/to] [street name]"
Distance to next movement Example
> 4.35 mi (7.0 km) Continue straight for 15 minutes to Rue Royale
Continue straight for 2 hours and 15 minutes to Exit 123: I-45 N / Bakerstown
< 4.35 mi (7.0 km) In 700 feet, turn left on Brightview Blvd
In 2.1 miles, exit to Exit 98: SR-76 / Chilltown

Instruction B

Instruction B is given at the point where the movement is expected to be 5 minutes away, but only if it's been 15-20 minutes since instruction A.

Format: "In [x] miles, [instruction] [on/to] [street name]"

examples
In 3.4 miles, turn left on Brightview Blvd
In 6 miles, exit right to Exit 98: SR-76 / Chilltown

Note: while the timing of the instruction is time-based, the instruction is given in distance.

Instruction C

Instruction C is given at a certain distance from the movement depending on your speed, unless the prior instruction was given too close to the timing of instruction C. The street name may or may not be included, depending on how long it has been since Instruction A (a couple minutes).

Format: "In [distance], [instruction] ([on/to] [street name])"

speed range distance example
0 – 43.5 mph (0 – 70 km/h) 1000 ft In a thousand feet, turn right
43.5 – 55.9 mph (70 – 90 km/h) 0.5 mi In half a mile, exit left
55.9 – 93.2 mph (90 – 150 km/h) 1 mi In one mile, stay to the right to I-75 N
93.2+ mph (150+ km/h) 2 mi In two miles, exit right

Instruction D

Instruction D is given every time, just before the movement (unless you make the turn before Waze has a chance to call it out).

Format: "[instruction] [on/to] [street name]"

examples
Turn right on Main St
Exit left to Exit 234B: Poydras St / Superdome


Notes

  • Instruction D is (virtually) always given.
  • Instruction A is given only if there will be instruction D and there is enough time for both.
  • Instruction C is given only if there was instruction A and there has been enough time since instruction A.
  • Instruction B is given only if there will be instruction C (and therefore there was instruction A) and there has been enough time since instruction A.

Combined instructions

If, based on the speed of the user, Waze expects a second movement to occur within about 30 seconds after the upcoming movement, it will tack on a second instruction to the end of instructions C and D.

examples
In half a mile, exit right, then stay to the left to Exit 26: I-71 N / Cleveland
Turn left on N High St, and then turn right on Arcadia Ave

Preposition choice

When a voice is selected that says street names, such as Jane, those names are preceded by "on" or "to" according to a couple factors:

  • Following an instruction to exit or stay to the left or right, Waze always says "to" and the street name.
  • Following an instruction to turn left or right, continue straight, make a U-turn or do anything at a roundabout, Waze says either "to" or "on" dependent upon the road type of the next segment past the instruction.
    • If the next segment is a  Ramp , Waze says "to" and the street name.
    • If the next segment is any other road type, Waze says "on" and the street name.

The word "to" at the beginning of any street name, which is common on ramp names, is never a factor in whether Waze says "to" or "on" and is actually ignored in audible instructions. This means that if the name of a ramp is inherited through an unnamed non-ramp segment, Waze will say "on" and will omit the "to" completely. For example, turning left through a roundabout made of non-ramp segments and onto a ramp with the name "to US-33 W / Lancaster" will produce the audible instruction "at the roundabout, turn left on US-33 W / Lancaster."
