- Updated NVIDIA STT services to align with Nemotron Speech defaults and configuration: `api_key` is now optional for local deployments, additional recognition settings are available (including alternatives, word offsets, and diarization), and streaming/segmented docs now reflect Nemotron Speech APIs.
- NVIDIA streaming STT now sets `TranscriptionFrame.finalized=True` when the provider marks a result as final, and preserves `language` on both `TranscriptionFrame` and `InterimTranscriptionFrame`.
