Parakeet and NeMo attribution

Pi Dictate uses NVIDIA's Parakeet-TDT 0.6B v3 model through NVIDIA NeMo. The repository does not redistribute the model weights. The installer downloads or copies the exact snapshot listed below.

Optional cloud providers

Cloud backends are opt-in and are not required for local mode. Pi Dictate does not redistribute Meta or OpenAI models and does not include either provider's SDK. The host service sends audio only after the selected provider session is authenticated and ready. Provider terms, retention, security, and billing policies apply to cloud audio and any keyword or prompt context sent with it.

Meta Model API Muse Voice Transcribe

• Announcement: https://research.meta.ai/blog/introducing-muse-voice-transcribe
• Speech-to-text guide: https://ai.developer.meta.com/docs/speech-to-text
• Realtime Voice API: https://ai.developer.meta.com/docs/api-reference/voice/realtime
• Voice event schemas: https://ai.developer.meta.com/docs/api-reference/voice/schemas
• Authentication: https://ai.developer.meta.com/docs/getting-started/authentication
• Meta terms: https://ai.meta.com/terms/

Pi Dictate uses only the documented api.meta.ai realtime endpoint and muse-voice-transcribe-1.0 contract. It does not use the undocumented shortwave.facebook.com Muse Code endpoint.

OpenAI Realtime transcription
