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 up-front. With this approach we still achieve very high accuracy compared to accent specific language packs.

Please note any languages outside this list are not explicitly supported. Only one language can be processed within each request. Each language above has a two-letter code (ISO639-1) or three-letter code (ISO639-3) that must be provided for any transcription request.
Domain Language
The Speechmatics SaaS also supports specialized language packs that enhance the requested transcription language with optimization for a particular field. This is particularly useful for increasing the accuracy for domains that have specific terminology. The domain packs build on our global languages to give the best accuracy.
