Convert data format of utterances
Important
LUIS will be retired on October 1st 2025 and starting April 1st 2023 you will not be able to create new LUIS resources. We recommend migrating your LUIS applications to conversational language understanding to benefit from continued product support and multilingual capabilities.
LUIS provides the following conversions of a user utterance before prediction.
- Speech to text using Azure AI Speech service.
