Hello Wall, Joel,
Welcome to Microsoft Q&A!
Thank you for your query regarding the support for structured text as an output format in the SV-SE language for Azure Speech-to-Text.
For Swedish (SV-SE), Azure Speech-to-Text does not currently support structured text as an output format. This means it cannot differentiate between speakers or provide speaker-attributed text in multi-speaker voice files.
Unfortunately, Microsoft has not announced a release date for adding support for structured text as an output format in the SV-SE language.
However, you can keep an eye on the Azure AI Speech Service release notes for updates on What's new in Azure AI Speech page will be updated accordingly with more details.
I hope you understand. And, if you have any further query do let us know.
Thank you!
