Languages
Speechmatics supports the following languages. Your ability to use any or all of the languages will depend on what languages you are contracted to use.
Speechmatics takes a global-first approach to our languages. In a single language pack, we aim to support many different accents and dialects. This simplifies your workflow when selecting which language to use, not requiring you to know which accent is being spoken in your audio upfront. With this approach we still achieve very high accuracy compared to accent-specific language packs.
