The phonetics tag can help text to speech systems to pronounce the name of several items (streets, towns, POIs, etc.) correctly. Obviously it must be language sensitive as the name tag itself. So phonetics corresponds to name, phonetics:de corresponds to name:de.
Already in use?
What system should be used to describe the phonetics. The International Phonetic Alphabet uses a lot of non latin letters but could be entered with unicode, though this might be hard to actually enter. Is there another widely accepted standard for entering phonetics?
- There is an all-ASCII representation of IPA called X-SAMPA. If we allow more than one method (e.g. both IPA and X-SAMPA), then this should be reflected in the key, e.g. name:de:ipa=... vs. name:de:sampa=... --Schuetzm 09:21, 20 April 2009 (UTC)
One possibility would be a subset of SSML (see http://www.w3.org/TR/speech-synthesis/#S3.1.9)
- Seems they are not defining a representation, but having the user specify the alphabet they want to use. --Schuetzm 09:21, 20 April 2009 (UTC)
What exactly should be represented? Phones or phonemes? I would prefer phonemes, because the actual phones can be derived from them if the language (variety) is known. --Schuetzm 09:21, 20 April 2009 (UTC)
- I recommend to use the international phonetic alphabet as it is already used in Wikipedia or unusually pronounced words and can be easily copied from there for place names.

Which parser are you referring to? A parser requiring tag ordering would seem to be broken in general. --SpeedEvil 16:14, 28 January 2010 (UTC)
I have already used the suffix :pronunciation for this purpose, giving values in IPA. Hence name:pronunciation=kærnuːsti for Carnoustie. This scheme is extensible in that it can be applied to any tag, not just name=*. Jonathan Bennett 17:41, 27 January 2010 (UTC)
- Sounds good to me. Where do you put the information for the language? --Lulu-Ann 19:52, 27 January 2010 (UTC)
- You'd just have multiple suffices, all separated with a colon, so:
or for other name tags:

- The problem with using :pronunciation is that there are several systems for indicating pronunciation. I suggest using:
* name:lang:IPA=* for IPA * name:lang:X-SAMPA=* for X-SAMPA * name:jp:okurigana=* for okurigana * and possibly name:cn:pinyin=* for pinyin, although perhaps that should count as a script.
