• Updated SpeechmaticsSTTService to use new Python Voice SDK with improved VAD, Smart Turn capabilities, and brings dramatic improvements to latency without any impact on accuracy. Use the turn_detection_mode parameter to control the endpointing of speech, with TurnDetectionMode.EXTERNAL (default), TurnDetectionMode.ADAPTIVE, or TurnDetectionMode.SMART_TURN.

            language=Language.EN,
            turn_detection_mode=SpeechmaticsSTTService.TurnDetectionMode.ADAPTIVE,
            speaker_active_format="<{speaker_id}>{text}</{speaker_id}>",
