Phone alignment matches spoken sounds with text, streamlining speech dataset creation and analysis. However, most trained aligners focus on Indo-European languages, leaving under-resourced languages unsupported. Developing new aligners for these languages requires expertise and large datasets, which are often scarce. Cross-language phone alignment offers a solution using aligners trained in one language to align speech in another, but it traditionally relies on expert-crafted phone mappings. Our tool, CrossPhon, automates this process, making cross-language phone alignment more efficient. In tests on 14 languages from 7 families, CrossPhon achieved agreement rates of 78.95% to 97.77% compared to human expert mappings and delivered competitive performance in cross-language phone alignment. CrossPhon provides an efficient, reliable solution for generating cross-language phone alignment in under-resourced languages, helping bridge the digital divide and efficiently study these languages.
