Introduction
Corti speech recognition is specifically designed for use in the healthcare domain. The automated speech recognition (ASR) language models are designed to balance recognition speed, performance, and accuracy. This page describes a tier system to categorize functionality and performance that is available per language. Each ASR endpoint supports different capabilities as described here.The
language codes listed below are used in API requests for both defining speech recognition language and document generation output language.You can query the API for document templates available by language. Learn more here.Corti speech recognition performance tiers

Speech recognition accuracy for async audio file processing via
/transcripts endpoint may be degraded as compared to real-time recognition via the /transcribe and /stream endpoints. An update is expected November 2025 to address the performance issue.Please contact us if you are interested in a language that is not listed here, need help with tiers and endpoint definitions, or have questions about how to use language codes in API requests.
