These proceedings contain the papers presented at the 2nd Workshop on the Use of Computational Methods in the Study of Endangered languages held in Honolulu, March 6–7, 2017. The workshop itself was co-located and took place after the 5th International Conference on Language Documentation and Conservation (ICLDC) at the University of Hawai‘i at Manoa. As the name implies, this is the second workshop held on the topic — the previous meeting was co-located with the ACL main conference in Baltimore, Maryland in 2014. The workshop covers a wide range of topics relevant to the study and documentation of endangered languages, ranging from technical papers on working systems and applications, to reports on community activities with supporting computational components. The purpose of the workshop is to bring together computational researchers, documentary linguists, and people involved with community efforts of language documentation and revitalization to take part in both formal and informal exchanges on how to integrate rapidly evolving language processing methods and tools into efforts of language description, documentation, and revitalization. The organizers are pleased with the range of papers, many of which highlight the importance of interdisciplinary work and interaction between the various communities that the workshop is aimed towards. We received 39 submissions as long papers, short papers, or extended abstracts, of which 23 were selected for this volume (59%). In the proceedings, all papers are either short (≤5 pages) or long (≤9 pages). In addition, the workshop also features presentations from representatives of the National Science Foundation (NSF). Two panel dicussions on the topic of interaction between computational linguistics and the documentation and revitalization community as well as future planning of ComputEL underlined the demand and necessity of a workshop of this nature. The organizing committee would like to thank the program committee for their thoughtful input on the submissions, as well as the organizers of ICLDC. We are also grateful to the NSF for funding part of the workshop (awards #1404352 and #1550905), and the Social Sciences and Humanities Research Council (SSHRC) of Canada for supporting the workshop through their Connections Outreach Grant #611-2016-0207.
