Read Sound and adjacent annotation files (TIMIT)...: if you open any sound file from the TIMIT corpus, the annotation files with the same name in the same folder are interpreted as a TextGrid and opened as well. Read Sound and adjacent annotation files (Buckeye)...: if you open any sound file from the Buckeye corpus, the annotation files with the same name in the same folder are interpreted as a TextGrid and opened as well. Backslash trigraphs for tone symbols: a? (a''), a? (a), ? (-5), ? (-4), ? (-3), ? (-2), ? (-1), ? (|u), ? (|d). Backslash trigraphs for diagonal arrows: ? (NE), ? (SE), ? (SW), ? (NW); the first two of these double as tone symbols. |
