T9 Slang
I removed the following text, as it is unsourced. The sources listed for this content were urban dictionary entries and a livejournal entry, neither are reliable sources. Feel free to put back any portion of this if reliable sources can be found:

 * Since there are multiple possible words for any given key sequence, the T9 interface will often initially
 * present a different word than the desired word. This gives rise to mental associations between otherwise
 * unrelated words that happen to share a T9 key sequence, and in at least one case, such a mapping has entered
 * the lexicon as slang: "book" as a substitute for "cool", based on the T9 key sequence 2-6-6-5. Another, less
 * subtle, example of an ambiguous key sequence with associations between the mappings is that of 2-6-2-5 which
 * yields both "cock" and "anal."

History?
When was this developed? How did it do in the market? Against what systems did it compete at the time? Shinobu 05:07, 1 September 2007 (UTC)

My product design history T9: Text on Nine Keys, added to External Links, answers many of these questions. Lawnjay (talk) 23:13, 3 July 2009 (UTC)

Algorithm?
Something about how T9 actually works would be nice. There's probably a good (or possibly less so) technical reason why it sometimes goes crazy and accepts/produces non-words. With a Swedish dictionary, it produces things like Michellellellellellelle and Gnageålning (the latter should be Incheckning, a fairly common word not found in the dictionary), and the reason is probably clear to someone who knows how T9 works.Carl T 18:29, 28 October 2007 (UTC)

T9 is also on Huawei Phones
I know this for a fact, as I have a Huawei phone that uses T9. Should I add this? TorontoLRT (talk) 14:18, 5 June 2010 (UTC)

Mixed languages
So from the text I understand that it works only for one language at the time. But I often type sentences in mixed languages and could this be the reason that T9 never works for me? Andries (talk) 20:05, 5 August 2010 (UTC)


 * Of course it doesn't mix languages. Dictonaries can contain some common words but not all. Actually it useless for non-latin alphabets as sending SMS with non-latin characters are sent as unicode and so the SMS lenght is cut in half. Technology that makes you pay 2x for the same SMS. So I do not use it for Latvian language for example. There is a need for two dictionary with latin(for SMS) and non-latin(web) letters but sadly it is never provided.

Poor quality
I used to have a Siemens cellphone with a comprehensive and extendable T9 dictionary. Unfortunately I lost it. While the Samsung replacement in many respects does its job well the T9 function misses so many words (Swedish) and suggests so many non-words and seems unable to learn anything that it is pretty useless. The T9 function can also be hard to turn on/off on Samsung since it is not in the menus and the manual of my first Samsung forgot to tell about this feature. I thought that maybe each manufacturer built their own dictionary database so that the fault would be Samsung's. I have later been told that the company making T9 was bought by some other company that dropped most of the support for small languages (what a horrific waste if the dictionaries already exist!). It would be interesting if this issue could be treated in the article. — Preceding unsigned comment added by 150.227.15.253 (talk) 13:52, 25 July 2012 (UTC)


 * Yeah but why did my Nokia think I always wanted to type "Nigger" even when I referenced my iTunes library? 2603:6010:6E46:7300:56C:DE2B:8EA7:1829 (talk) 05:41, 23 May 2022 (UTC)

Who created T9?
I read a news article that stated Martin King as a co-creator of the T9. Who is the other person? Were these engineers of Tegic? news article --88.115.26.13 (talk) 06:03, 25 September 2012 (UTC)

There should be a Criticism entry
On some phones I resolutely cannot get the phone to produce the word I want. The fact that there is no standard for T9 and no test suite should be brought out. — Preceding unsigned comment added by 213.187.52.248 (talk) 19:45, 3 March 2014 (UTC)
