黑脚语是一种濒危语言，需要记录、分析和保护。黑脚语的学习和教学都很有挑战性，因为黑脚语是一种音调重音语言，相同字符的单词在音调变化时可能会有不同的含义。语言学研究人员正在努力创造一种名为“音高艺术”的视觉辅助工具，来教授音高变化的细微差别。然而，用于创建音高艺术的现有技术无法准确地指示音高的变化，并且需要跨多个应用程序进行耗时的工作。为了解决这个问题，这个项目提出了一个名为MeTILDA （Melodic Transcription in Language Documentation and Application）的系统，以提供新的音频分析形式，并自动化创建音高艺术的过程。MeTILDA为各种利益相关者提供价值。为语言学研究者提供了分析和比较黑脚语的工具。老师们从母语人士那里收集单词和录音来教学生。学生有能力将自己的黑脚单词的发音与母语人士的发音进行比较。我们还提出了一种新的音频分析形式，称为感知尺度，以提供更有效的音高运动感知变化的视觉效果。通过与该领域的专家合作，我们已经验证了MeTILDA在使用感知尺度创建音高艺术方面的有效性。
Blackfoot language is an endangered language that needs to be documented, analyzed, and preserved. Blackfoot is challenging to learn and teach because it is a pitch accent language whose words with same characters can take on different meanings when changing in pitch. Linguistics researchers are working to create visual aids, called Pitch Art, to teach the nuance in pitch changes. However, the existing techniques used to create Pitch Art fail to accurately indicate changes in pitch and require time-consuming work across multiple applications. To address this issue, this project proposes a system called MeTILDA (Melodic Transcription in Language Documentation and Application) to provide new forms of audio analysis and to automate the process of creating Pitch Art. MeTILDA provides value to a variety of stakeholders. Linguistics researchers are provided with tools to analyze and compare Blackfoot speeches. Teachers are given collections of words and recordings from native speakers to teach students. Students are given the ability to compare their own pronunciation of Blackfoot words to that of native speakers. We also present a new form of audio analysis, called perceptual scale, to provide more effective visuals of perceived changes in pitch movement. By collaborating with domain experts in this field, we have validated the effectiveness of MeTILDA in creating Pitch Art using the perceptual scale.
