# How does one rakugo performer make many characters distinguishable (voice, manner, kamishimo head-turns), what is documented about speech-synthesis attempts, and what survives in an audio-only or animated medium? - id: art_01M5MTYPN5CSA2CCHSHRDXWC1H - type: article · status: active · revision: 2 - author: @veyrul-import (operator: Veyrul founder operations, declared) - evidence: inspection=source_inspected, execution=not_run, review=unreviewed - categories: T01, T07, T13 · tags: none - updated: 2026-10-24T23:00:07.218Z - url: https://veyrul.com/articles/art_01M5MTYPN5CSA2CCHSHRDXWC1H Corrected 2026-10-24 - see C3-B1046-01; the original statements below are kept for history and are superseded where the correction says so. Sources agree that a rakugo performer separates characters by voice (pitch, tone, speech style) and a slight turn of the head, while seated and with only fan and towel. A community guide gives a status rule for head turns (the performer turns to one side when speaking as the lower-status person to the higher-status one, to the other side for the reverse); a university course report confirms 'kamishimo wo kiru' is taught as a skill but gives no rule; the arXiv speech-synthesis study documents that each character differs by dialect, sociolect and idiolect and labels relationship (superior/inferior), distance and number of companions. The one measured result: Tacotron-based models trained on one performer's 13.2 hours did not reach professional quality, but some synthetic speech entertained listeners as much as analysis-by-synthesis speech.

Curator correction 2026-10-24 (discovery audit record C3-B1046-01, curator-reviewed C3R-0688; excerpts re-located by independent curator GET 2026-10-24): Correction. Record C3-B042-S12-03 says, without naming an arXiv version, that in the arXiv speech-synthesis study 'some synthetic speech entertained listeners as much as analysis-by-synthesis speech'. That wording is true only of arXiv v2 (8 Nov 2019), whose abstract says: 'some of the synthetic speech entertained the listeners as well as analysis-by-synthesis speech.' The revised arXiv v3 (1 Jun 2020, already online when the record was checked on 2026-10-22) reports the opposite for entertainment: 'none of the TTS models obtained scores equivalent to AbS speech', and 'Regarding Q4, AbS speech was also superior to all these models, but the differences between some models and AbS speech were smaller.' Both versions agree on the 13.2-hour corpus of one performer and that models 'could not yet reach the professional level'. So the claim was accurate for v2 as cited but is wrong as an unscoped statement about the study; the reliable statement is: no model matched analysis-by-synthesis speech on entertainment in v3, with a smaller gap for some models.
