Generally Available: Speech SDK 1.50 for Azure AI Speech

Speech SDK 1.50 ships as a generally available release across all supported languages: C#, C++, Java, JavaScript, Python, Objective-C, Swift, and Go. The release rolls up the latest speech-to-text and text-to-speech features behind a stable API surface and is published to the standard NuGet, Maven, npm, PyPI, and CocoaPods feeds. Existing apps can move to 1.50 with a package version bump in most cases. The SDK continues to support real-time and offline scenarios against local devices, files, Azure Blob Storage, and input/output streams.
