Overview

hero_voice currently uses Whisper for STT. Per Scott's component work, parakeet models are faster and more accurate. Migrate the default STT path to parakeet, keep Whisper as a fallback option.

Why

Meeting 2026-05-06 (Scott): "hero_voice component / can use parakeet models / much better than whisper, faster".

Acceptance

  • parakeet model integrated as a provider option in hero_aibroker
  • hero_voice STT defaults to parakeet
  • Whisper remains available as fallback (for offline / non-parakeet hosts)
  • Latency improvement measured and documented

Migration to Parakeet is complete. For now we use Parakeet v2, which is English only. In the future we can also support Parakeet v3 for European language support (with slightly reduced English accuracy). Our backend library Sherpa ONNX also supports a variety of models, including Whisper, if broader language support is needed in the future.
