• STT services now reconnect safely when settings change: reconnection is deferred until the current user turn ends (i.e., until UserStoppedSpeakingFrame is received) rather than interrupting an active speech session. Audio frames received while the reconnect is in progress are buffered and replayed once the new connection is ready. CartesiaSTTService and DeepgramSTTService both use this new behavior.
