Summary

Adds documentation highlighting Universal-3 Pro's strength with regional dialects and local speech variants across all 6 supported languages (English, Spanish, French, German, Portuguese, Italian). This was prompted by customer feedback confirming strong dialect performance.

Changes across 4 files:

  • supported-languages.mdx — New "Regional dialects and variants" section under U3 Pro with per-language accordion tables listing ~45 dialects/variants with descriptions
  • universal-3-pro.mdx (async) — Added dialect mention to the page overview and a new "Regional dialect recognition" row in the key capabilities table
  • universal-3-pro.mdx (intro) — Added dialect sentence to the overview paragraph
  • models.mdx — Added "Regional dialect and local variant recognition" to the U3 Pro card and description paragraph

Review & Testing Checklist for Human

  • Verify dialect list accuracy: Only Canadian French, Spanglish, and Brazilian Portuguese are confirmed working by customers. The remaining ~42 dialects listed need to be tested before publishing. Review whether each listed dialect is something U3 Pro actually handles well, and remove any that don't meet the bar.
  • Review the "Regional dialect recognition" row in the key capabilities table (universal-3-pro.mdx line 230): This table describes what prompts can do, but dialect recognition is an out-of-the-box capability — consider whether this row belongs here or should be called out differently.
  • Check rendered output: Preview the accordion tables on the supported-languages page to verify MDX renders correctly (tables inside <Accordion> inside <AccordionGroup>).
  • Phrasing review: The same example set ("Canadian French, Brazilian Portuguese, Spanglish, Bavarian German") appears in 4 places. Confirm these are the right lead examples and that the marketing tone is appropriate for the docs.
  • Streaming docs: The U3 Pro streaming page was not updated — decide if dialect mentions should be added there too.

Recommended test plan: Deploy to a docs preview environment and visually verify the new accordion sections render properly on the supported-languages page. Then run transcription tests against sample audio for each listed dialect to validate claims before merging.

Notes

…cognition
