Microsoft Teams: Interpreter - Simultaneous mode enhancements

We’re raising the bar on clarity and control with Interpreter. Admins can fully disable voice simulation via PowerShell when needed. Each speaker is automatically assigned a distinct voice, making multi-speaker conversations easier to follow. We’re reducing distractions by showing shimmer effects only to Interpreter users. We’ve added audio notifications to confirm activation, and we’ve introduced in-product feedback mechanisms so users can easily share their input.
