Camlin ASR is our own speech recognition engine. It is built on open Whisper model weights, which Nuamedia fine-tunes for Australian and US English and serves from our own infrastructure in AWS Sydney. Audio sent to Camlin ASR is processed by Nuamedia; it is not sent to the authors of the base weights.

• Whisper large-v3-turbo

  Base of Camlin ASR for US English, and of the Australian profile in testing

  Licence: MIT. Copyright (c) 2022 OpenAI.

• Whisper small

  Base of the current Australian profile (camlin-au), fine-tuned by Nuamedia

  Licence: MIT (github.com/openai/whisper); also offered under the Apache License 2.0 on Hugging Face. Copyright (c) 2022 OpenAI.

Nuamedia's changes: LoRA adapters trained on Australian English (and, in testing, Australian data on the large-v3-turbo base), and decoding safeguards that stop transcripts running on past the end of speech.
