Judoonese

The Judoon language was composed of many one-syllable words ending in a vowel, generally an "o" sound (such as "blo mo co jo") but occasionally an "a". (TV: Smith and Jones, PROSE: Judgement of the Judoon) Each sentence was composed of several of these words strung together. The Tenth Doctor could speak the language of the Judoon, and did so when he arrived at the Shadow Proclamation. (TV: Smith and Jones, The Stolen Earth)

Despite the TARDIS containing a telepathic translator that turns all alien language into English, the Judoon language does not seem to be translated, even with the TARDIS and The Doctor present in their company.
