This page was created by Kent last year based on sketch’s musings on and testing of TTS instructions. Does anyone here have an objection to including it in the US wiki?
Edit: Info added on non-TTS instructions alongside the original info on TTS instructions from Jane. Thread title updated to indicate the new proposed title of the page
With some additional explanation in the heading I think it’d be a sensible addition.
We could also include in a separate section observations about preposition choice… I’m pretty sure that “to” is always used following a “stay” or “exit” command, but with a “turn”, “continue” or “U turn” command, the preposition depends on the road type of the segment you’re going to (or “s-out”). Specifically, it’s “to” if the segment is a ramp type (“turn left to I-10 W / Baton Rouge”) but “on” if the segment is any other type (“continue straight on Carter St”).
Y’all keep y’all’s ears open and let me know if you hear the same.
Go for it. This page is long overdue.
Yes, I did some testing using mock GPS and found this out too. The road type thing applies to numbered roundabout exits and left and right turns. Jane never says the street name after continue and U-turn instructions through roundabouts
No, but she does after Continue and U-turn instructions set via TIO, and I’m fairly certain both exhibit the road type-affected preposition shift.
Yeah I think you’re right. Normal continue and U-turn instructions say “to” or “on” based upon road type. Roundabout continue and U-turn instructions are different, for some reason. I set up a U-turn TIO into an unnamed ramp. I am expecting Jane to say “make a U-turn to [the following highway name]” but we seem to have a tile update delay so can’t test yet.
I also will make a roundabout into ramps and test there at a dumbbell interchange. For this route Jane currently says “at the roundabout turn left on US-33 W / Lancaster.” With the roundabout segments becoming ramps, I expect her to say “at the roundabout turn left to US-33 W / Lancaster.” That would be more accurate, but pretty inconsequential. Just trying to cover everything.
Had to wait to test due to the tile delay, but the road-type-based choice of “to” or “on” applies on all turn left, turn right, continue or U-turn instructions, as well as all roundabout instructions. So the last thing to do is write some explanatory stuff in the lead. I can do that and also add the info at the end on preposition choice at the end
I added lead, preposition choice and combined instructions sections.
Since only the street names are technically TTS, and the rest is just S (not converted from text), I propose moving this to a main page with the title “audible instructions”. If no one has any additions, I can do this within a few days.
No, that’s not accurate. This structure is only followed with TTS. The prerecorded instructions are much more simplistic and not flexible enough to do all the same things that TTS does. Anything time-based, anything more than 1 mile away, etc., none of that is possible without TTS.
Thanks for clarifying. I will distinguish between the two types of voices and their instructions here.
Alright, I have distinguished TTS and non-TTS voices and added info on non-TTS instructions, after doing some more testing. How does this look?
It is a bit confusing on the order or A and D at the beginning of the explanations.
Would it be worthwhile to say that D is always the turn instruction? The A, B, and C are the heads up alerts/ warnings?
Main reason I ask is D by itself is listed first in the list and not explained. Then A is said to occur first unless not enough time then only D is given.
Another way to do this is to change what the A, B, C, and D represent. So A is the actual turn instruction. Then the current continue statement (now A) becomes B. Etc
I’ve wondered about this too but don’t think there’s a better way to use A-D. What about just naming them, the way I’ve named the non-TTS instructions? The TTS instructions could be named initial, wake up, approach and final.
That could work, but it is not as elegant as the table of:
D
A, D
A, B, D
A, B, C, D
so maybe name them and put the letter after them for the table and put the table after the explanation? (instead of before it?)
that is a combination of both ways and should be more comprehensible.
Alright, I did this for the TTS instructions and also assigned numbers 1 to 3 to non-TTS instructions.
It’s good, I like the names and the use of 123 to distinguish from ABCD.
Looks good and is much more understandable for initial read thru. Great job.
Published! That was more work than I thought it would be, listening and taking notes 
Great job on this! Thank you.
i noticed when using TTS override on a JB path for a turn to a ramp waze used the preposition “on” for the instruction. the JB path was MH, MH, ramp. so it seems waze is using the preposition for the first segment type after the first node, MH in this case. might be worth mentioning in the Preposition choice section.
