Oral Performance Structure Mapper
A research tool that turns audio recordings of oral storytelling performances into node-link diagrams of episodes, characters and repeated motifs, letting folklorists compare versions across regions and languages.
Concept
A research workbench for folklorists and oral-literature scholars. The researcher uploads a field recording (or transcript) of an oral performance — a prose tale, praise poem, epic or drama. The tool applies the LLM-based spoken-content extraction demonstrated by Orality [1] to pull key elements out of the raw, disfluent audio and lay them out as an interactive node-link diagram: episode nodes, character and motif nodes, repetition and call-and-response markers, and performer–audience interjections. Each map is tagged with the genre categories the survey establishes (poetry, prose, drum language, drama) plus language, region and occasion [0]. The core capability is comparison: overlay two or more tellings and the tool highlights where episodes and motifs converge, diverge or drop out — producing motif-diff figures ready for publication and teaching.
Why now
Two things now line up. First, the revised edition provides the field's canonical genre taxonomy and comparative framing for African oral literature, freely available in digital form [0]. Second, Orality demonstrates that LLMs can already convert messy spoken content into structured node-link semantic diagrams [1]. Combining a demonstrated speech-to-diagram pipeline with a canonical taxonomy makes automated structural mapping and cross-version comparison of oral performances feasible for the first time.

AI assessment
A niche but high-utility research tool that effectively bridges a specific academic taxonomy with a proven technical pipeline for structural analysis of oral traditions.
- Evidence strength 4/5
- The idea logically combines a technical capability (Orality's speech-to-graph pipeline) with a domain-specific framework (Finnegan's taxonomy), though the 'diffing' of motifs is an extrapolation of the research.
- Market pull 2/5
- The target users are academic institutions and archives with historically limited budgets, making the commercial viability low despite the high utility for the researchers.
- Novelty & moat 3/5
- While similar to the 'Semantic Thought Mapper', it differentiates itself by applying the technology to a specific scholarly methodology (comparative folklore) rather than general brainstorming.
- Feasibility 5/5
- The core technical hurdle has already been solved by the Orality paper, meaning an MVP could be built quickly by wrapping that pipeline around a specific dataset.
- Wedge clarity 4/5
- The 'motif-diff' for comparing versions of stories across regions is a sharp, specific entry point that provides immediate value to folklorists.
- Simplicity / focus 5/5
- The product is focused on a single, clear function: converting oral performances into comparable structural maps.

Who benefits
- World Oral Literature Projectorganization
Its mission is documenting oral traditions and it co-publishes the series this book belongs to; the mapper turns the recordings it exists to safeguard into analyzable, comparative data.
- Indiana University Archives of Traditional Musicorganization
One of the world's largest ethnographic sound archives with extensive African field recordings; the mapper lets staff and visiting researchers generate structural descriptions and motif indexes at scale.
- University of Ibadanorganization
A leading center for African oral-literature scholarship; faculty comparing tale variants across Yoruba-speaking communities could use the motif-diff overlays directly in research and teaching.
- Fourah Bay College, University of Sierra Leoneorganization
Its scholars document West African oral traditions; the mapper automates the by-hand structural comparison of narrative recordings that their comparative research depends on.
- African Studies Associationorganization
Its folklorist and anthropologist members are the direct users; the tool lowers the cost of comparative oral-performance analysis for individual researchers.
