Multilingual Transcription

You may find yourself with customers that speak in more than one language ("code switch") in a single meeting. This requires a special configuration to produce an accurate transcript, since standard transcription configurations will interpret the entire conversation as taking place in a single language. Some of our supported transcription providers offer code switching configurations in order to handle these situations.

Code switching is supported for both async and real-time models, but quality will generally be higher for async models, so we recommend using them unless you require transcription data in real time.

Transcription providers that support code-switching

To get started with using any of these providers, you'll need to sign up for an account, get an API key, and add it to the Recall transcription dashboard.
