Imrpove pronouciation of UK road numbers

Reported by: Owned by: KaZeR

Component: core Version: git master
Severity: Keywords:


The normal rules for pronouncing road numbers in the UK are:

  • Always use a long A pronounciation - i.e. rhymes with Hay, not like in cat.
  • Zeros are usually pronounced "Oh" (although that is possibly a matter of preference)
  • If the number is less than 100, say it in full - e.g.
    • A42 => A forty two
    • M25 => Em twenty five
  • Otherwise say it digit by digit
    • A121 => A one two one
    • A4144 => A four one four four
    • A4074 => A four oh seven four
  • but if it ends in zeros, merge those into the last number, so
    • A420 => A four twenty
    • A400 => A four hundred
    • B4000 => Bee four thousand
    • A4700 => A four seven hundred

Prefix the number with "the". E.g. "Turn left onto the A four twenty", not just "Turn left onto A four twenty".

Some people do pronounce some road names different to the above rules - I've heard the A4074 called "A forty seventy four", for example - but the above rules are probably a good starting point, and I can't think of any examples that sound wrong when parsed with them.

I have been thinking about your ticket while using Navit, to see if in my own language (French) it would bring an improvement. I came to the conclusion that it is really related to english-speaking people (if it's usually done that way too in other languages, please people correct me).

I will close the ticket for now, but if you want to submit a patch for a configurable speech output with theses rules, feel free to do so, and i'll review it.
