 ### Changed
 
+- Changed the default model for both `ElevenLabsTTSService` and
+  `ElevenLabsHttpTTSService` to `eleven_turbo_v2_5`. The rationale for this
+  change is that the Turbo v2.5 model exhibits the most stable voice quality
+  along with very low latency TTFB; latencies are on par with the Flash v2.5
+  model. Also, the Turbo v2.5 model outputs word/timestamp alignment data with
+  correct spacing.
+
 - The development runners `/connect` and `/start` endpoint now both return
   `dailyRoom` and `dailyToken` in place of the previous `room_url` and `token`.
