 ### Fixes
 
+- TTS: add missing OpenAI voices (ballad, cedar, juniper, marin, verse) to the allowlist so they are recognized instead of silently falling back to Edge TTS. (#2393)
 - Cron: scheduler reliability (timer drift, restart catch-up, lock contention, stale running markers). (#10776) Thanks @tyler6204.
 - Cron: store migration hardening (legacy field migration, parse error handling, explicit delivery mode persistence). (#10776) Thanks @tyler6204.
 - Memory: set Voyage embeddings `input_type` for improved retrieval. (#10818) Thanks @mcinteerj.
