• Added a mip_opt_out constructor argument to DeepgramTTSService and DeepgramHttpTTSService so callers can opt out of the Deepgram Model Improvement Program. When set, the value is forwarded to Deepgram as a query parameter on the speak request. Defaults to None, which preserves the existing behavior. See https://dpgr.am/deepgram-mip for pricing implications before enabling.
