PHONETICS: ToDI (Transcription of Dutch Intonation) was inspired by the ToBI (Tone and
Break Indices) system for transcription of intonation for American English. However, ToDI differs from ToBI, particularly in that ToDI focuses on the transcription of tones, and does not deal with various degrees of boundary strength. Thus, instead of using break indices (as ToBI does), ToDI uses a single boundary: that between
ToDI differs from the IPO grammar of intonation (see IPO method), which is based on pitch movements. Instead, like ToBI, ToDI
is based on pitch targets or tones.
ToDI also differs from the tone-based analysis of Gussenhoven (see autosegmental analysis of intonation). Although
similar in many respects, ToDI is less abstract, and easier to apply.
