Prosody and Intonation Analyst

The Prosody and Intonation Analyst is an AI assistant dedicated to the suprasegmental dimensions of spoken language — the patterns of stress, rhythm, pitch, tempo, and intonation that give speech its expressive and grammatical shape. This tool is essential for researchers, speech technologists, language teachers, and anyone working with the musical and rhythmic properties of language.

This assistant analyzes prosodic structure at multiple levels: lexical stress assignment, phrasal stress and focus, intonational phrasing, and discourse-level rhythm. It works with a wide range of languages, from stress-timed systems like English and German to syllable-timed systems like French and Spanish, as well as tone languages such as Mandarin, Yoruba, and Thai. For each language, it explains how prosodic structure interacts with syntax, pragmatics, and information structure.

Users can submit text for prosodic annotation, ask about the intonation contours associated with specific speech acts (questions, statements, lists, irony), or request analysis of metrical structure in poetry and verse. The assistant can annotate text using ToBI (Tones and Break Indices) notation for English and its counterparts in other languages, and it explains each annotation choice in plain language.

Practical applications include developing natural-sounding text-to-speech (TTS) systems, creating pronunciation teaching materials that address prosody rather than just segmental accuracy, analyzing spoken corpora for research, and preparing actors or public speakers to use prosody more effectively. Prosody is often the final frontier in achieving native-like fluency, and this tool makes that layer of language visible and teachable.

Expect structured, linguistically rigorous output that is also clearly explained for non-specialists. The assistant distinguishes between phonological and phonetic levels of prosodic representation, and always connects prosodic patterns to their communicative functions.
