Update Base Path in Code
When migrating from version 3.1 to 3.2 of the Speech to text REST API, you must update the base path in your code from /speechtotext/v3.1 to /speechtotext/v3.2. This ensures correct access to the required models and functionalities in the eastus region or any specified region.
Batch Transcription Pricing Update
With the introduction of Speech to text REST API v3.2, there is a new pricing structure for batch transcription services. It's essential to review the updated pricing guide to understand the cost implications of using batch transcription via the latest API version.
Backwards Compatibility Limitations
Avoid using older versions like Speech to text REST API v3.0 or v3.1 to retrieve transcriptions created with v3.2. Such attempts may result in errors indicating version incompatibility. Always ensure compatibility by using API version v3.2 or higher for accessing relevant transcriptions.
Language Identification Modes
In Speech to text REST API v3.2, the LanguageIdentificationMode has been introduced within LanguageIdentificationProperties. It offers two modes, Continuous and Single, for language identification. Continuous identification is set as the default mode, providing flexibility in language identification operations.
