Linguistically, Chochenyo, Tamyen and Ramaytush are thought to have been dialects of a single language. The speech of the last two native speakers of Chochenyo was documented in the 1920s in the unpublished fieldnotes of the Bureau of American Ethnology linguist John Peabody Harrington. The final native speaker of the language was José Guzmán who died in 1934 in Niles, California.
The Muwekma Ohlone Tribe, which (as of 2007) is petitioning for U.S. federal recognition, has made efforts to revive the language. As of 2004, "the Chochenyo database being developed by the tribe ... [contained] from 1,000 to 2,000 basic words." By 2009, many students were able to carry on conversations in the Chochenyo language. Through both successful word formation, as well as extending documented words, the Chochenyo dictionary has grown significantly throughout the early 21st Century. During the canonization of Saint Junípero Serra on September 23, 2015, the first reading at Mass was read in Chochenyo by Vincent Medina, a Muwekma Ohlone tribal member.
