MeTILDA and Pitch Art


Melodic Transcription of Indigenous Language Documentation and Application (MeTILDA) is an ongoing project donducted in collaboration with Min Chen (University of Washington-Bothell), James Randall (Music, University of Montana), and Naatosi Fish (Blackfeet, UM alum).

This tool lets teachers draw Pitch Art, and the scale of the pitch movement is adjusted so that it matches people’s visual perception. It also includes features for language teaching and learning. 

MeTILDA is still under-development and not yet available to wide users, though the project team's goal includes making it availbale to interested researchers, teachers, and students. Inception of the project and other related concepts (collaborative community-based research) are prosented at various conference. The team receives feedback from various Indigenous community linguists and linguists work with communities that they would like to try the tool when available. The project team welcomes community and academic members who would vounteer to test MeTIDLA.

Pitch Art

Pitch Art is a vidual guide used to teach word melody of language of which prosodic caharacteristic is composed of particular pitch movements throughout a word. The idea is to help English-speaking learners realize the salient prosodic characteristic of the target languages is distinct from that of English, and assist them practice and acquire pronunciation obtaining as accuare word melody as possible.

Naatosi Fish teaches Blackfoot with Pitch ArtThe idea of the Pitch Art is developed out of conversations with the community collaborator, Naatosi Fish who took a lead on its development. The Pitch Art images shown above are developed based on word melody in Blackfoot. These Pitch Art images were intriduced to students in Blackfoot language course when Fish taught in 2017-2019.  The image in left is taken in Fall 2018. There are more pitch melodies in Blackfoot to be researched which can be applied to Pitch Art creation. Initial impression among the students who were introduced to Pitch Art is promissiong. Since the prosodic difference among languages are not conscious knowledge, the purpose and the use of these images need to be instructed for the effectiveness. See articles below about the development background and initial research in its effect.
