Language coverage by plan

Each plan below lists the languages it supports. The Free plan runs entirely on your device, so it covers the languages we can ship a voice model for; the online plans reach considerably further. Find your language, and you can see at a glance which plan you need.

Both sides of a conversation need to be supported by the plan you choose. If either language is unavailable on a plan, that speaker will not be captioned.

Two exceptions worth naming: Latvian and Lithuanian can be translated into, so you can read Latvian and Lithuanian, but DuoVox cannot yet caption speech in either — on any plan.

Free runs entirely on your device and never sends audio anywhere. Standard and Professional use online services for higher accuracy, and fall back to on-device processing if the connection drops.

Supported does not mean identical accuracy. Accuracy varies by language, accent, microphone and background noise, and some languages perform noticeably better than others on the same plan. Treat this page as a list of what is available, not a guarantee of how well it will perform for you.

Language availability depends on third-party services and on-device models and may change without notice. We update this page when it does; the date below shows when it was last generated.

DuoVox is an assistive aid, not a substitute for a qualified human interpreter, and is not certified for regulated medical or legal use. See our Terms of Use.

Regional variants (for example Traditional Chinese and British English) are selected separately in the app and are not listed individually here.
