Pipeline for Convergence Detection Based on Read Speech](https://md.research.elamur.ai/free/en/papers/sward-2026-how-much-data-stable-formant/)** *(2026)* Vowel formant studies usually measure short, isolated utterances recorded in a lab. This leaves an open question: how many vowel tokens are needed before a speaker's average F1, F2 and F3 stop changing in a meaningful way? The authors address it with a large corpus of English audiobooks, 3,384 chapters totalling… ## Co-authors here 1 co-author with a page, the most papers together first. - [Johan Sjons](https://md.research.elamur.ai/free/en/authors/johan-sjons/) ×2
