๐คฏ Phonetic Universal Uncovered! ๐ค
We analyzed over 60,000 speakers across 75 languages and confirmed a universal phonetic bias: High vowels (like /i, u/) are consistently spoken with a slightly higher pitch (F0) than low vowels (/a/).
For everyone working on the intersections between linguistic and computational research, consider submitting to the upcoming SCiL! We're very excited that it will be co-located with ACL 2026 as a workshop, and we've also received NSF funding to help cover costs.

The differences are small but consistent in direction, supporting a biomechanical account critically tied to uniform phonetic targets across vowels. At the same time, variation in effect size across languages suggests speakers differ in how strongly this uniformity is realized
02.10.2025 16:46 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 0Our findings:
๐ Clear crosslinguistic biasโhigh vowels are shorter than low vowels
โก๏ธ But no systematic difference between high front vs. high back vowels
Previous explanations have focused on two explanations:
๐ฃ๏ธAutomatic accounts
๐Speaker control
As a novel contribution, we reinterpret intrinsic vowel duration as a statistical universal emerging from the competing pressures of target uniformity and enhancement
We provide a large-scale crosslinguistic corpus analysis of intrinsic vowel duration โ the observation that high vowels (like /i/ or /u/) tend to be shorter than low vowels (like /a/)
Our dataset:
โ
60+ languages
โ
16 language families

๐ซThis was joint work with @mzhang89.bsky.social, Aref Farhadipour, Annie Baker, Jiachen Ma, and Bogdan Pricop
Pairs below this were more likely perceived as different speakers and above, as the same speaker. Of course thereโs no ground truth, so you can also choose your own threshold
The similarity scores, paper, and code can be found at the below links
Happy data cleaning ๐
We ran automatic speaker verification (ResNet-293 trained w/ multilingual VoxBlink2) to obtain similarity scores among files for each client ID. Based on previous thresholds and a perceptual evaluation, we found an optimal threshold of ~0.35โ0.40 for same vs diff speakers
