+# What's New: Week of June 1, 2026
+
+1. **xAI Speech-to-Text and Text-to-Speech**: xAI is now available as a transcriber (STT) and voice (TTS) provider for assistants.
+
+2. **Upgraded Vapi Voices**: A new text-to-speech model powering [Vapi Voices](https://docs.vapi.ai/providers/voice/vapi-voices) makes them sound more authentic, human, and consistent — at ~50% lower cost.
+    - Existing deployments don't change automatically — opt in by setting `version: 2` on the voice configuration via the API or Dashboard. See [Vapi Voices](https://docs.vapi.ai/providers/voice/vapi-voices) for supported voices and audio samples.
+
+3. **Pronunciation Dictionaries in the Dashboard**: The Assistants view now supports creating new [pronunciation dictionaries](https://docs.vapi.ai/assistants/pronunciation-dictionaries) directly from the dashboard.
+
+4. **Phone Number Fixes**: Improvements to phone number creation and listing.
+    - The Phone Numbers list no longer breaks on rows with no number or SIP URI.
+    - Creating a phone number now validates its Vapi identifier up front.
