Supported languages - Langcraft Speech API Docs

This API accepts both a base language code (lang) and a more specific dialect code (dialect).

Use lang for the base language (for example en, es, fr, zh).
Use dialect when you want a specific regional or stylistic variant of a language (for example US vs UK English).
