The list was updated yesterday with the results for most of the abbreviations and capitalization variations for:
Boro, Borough, Center, Centers, Centre, Estate, Estates, Rail Road, Ranch Road, Ranch to Market, Rural Route, State Highway, Township, Township Road.
Update: Parkway and Parkways also added to list.
The most significant change was the addition of a new column to reflect the test results for both audio files that are created by Waze.
After tweaking the text more today, here is the note that was added to the file to explain the change:
In the Text-to-Speech (TTS) Abbreviations in Waze Clients
Test List for North America, GizmoGuy wrote wrote:
• Waze creates two TTS audio files for every routed road segment on the Android. One file speaks just the names contained in the segment name property. The other prefixes the segment name with the word "at". (On iOS devices, only the prefixed files have been found thus far.) It was not until late 2012 that a distinction in the TTS results between the two files was noticed. Testing of both files started on 2013-01-12, when a second result column was added. Therefore, until all items are re-tested, an entry in the Non "at" prefixed audio file column, will be either for the prefixed or the non-prefixed results if the "at" prefixed audio file column is empty.
I have not yet edited the opening post to reflect this.
