Welcome to the 1.2.12.0 version of the Microsoft Flight Simulator Alpha!

Hello everybody,

Today’s update is a small Quality of Life update to address some important issues from Alpha 1.2.10.0.Thank you for your feedback!

Bug Fixes and QoL Improvements

➡️ Azure TTS – This build includes an improved method of generating speech for radio communications. The Azure Custom Voice method uses cloud computing and sophisticated real-time models to better simulate real speech. This is a feature that we are exploring for future application, but the audio team needs actual usage data on it in order to determine its viability. Please feel free to let us know what you think.

➡️ Fixed Icing issue in Airbus A320 Neo – Instruments will no longer fail, reducing airspeed to zero when encountering icing

➡️ SDK updates – SDK updates and fixes for 3rd party partner developers
