Speech to Text Performance Tiers
Corti speech to text uses a tier system to categorize functionality and performance that is available per language:| Tier | Description | |
|---|---|---|
| Base | AI-powered speech recognition, ready to integrate with healthcare IT solutions | Up to 1,000 |
| Enhanced | Base plus optimized medical vocabulary for a variety of specialties and improved support for real-time dictation | 1,000-99,999 |
| Premier | Enhanced plus speech to text models delivering the best performance in terms of accuracy, quality, and latency | 100,000+ |

outputLanguage parameter in POST/documents requests. Template(s) or section(s) in the defined output must be available for successful document generation.2 Speech to text accuracy for async audio file processing via /transcripts endpoint may be degraded as compared to real-time recognition via the /transcribe and /stream endpoints. Further model updates are in progress to address the performance limitation.3 Use language code gsw-CH for dialectical Swiss German workflows (e.g., conversational AI scribing), and language code de-CH when Swiss High German is spoken (e.g., dictation).4 For Swiss German /stream configuration: Use gsw-CH for primaryLanguage as you transcribe dialectical spoken to written Swiss High German, and use de-CH for the facts outputLanguage.Languages Available for Exploration

Language Translation
- Translation (audio capture in one language with transcript output in a different language) is not officially supported in the Corti API at this time.
- Some general support for translation of
transcriptsin English tofactsin other languages (e.g. German, French, Danish, etc.) is available in stream or extract Facts requests. - Additional translation language-pair combinations are not quality assessed or performance benchmarked.
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.
