Directory Layout

​
Download Options

  1. Git LFS clone: 
    git lfs install
git clone https://huggingface.co/FluidInference/parakeet-tdt-0.6b-v3-coreml
  2. HuggingFace web UI — download .tar archives
  3. Copy from cache — from a machine that already ran downloadAndLoad (macOS: ~/Library/Application Support/FluidAudio/Models/<repo>)

​
Loading Without Downloads

import FluidAudio

let repoDirectory = URL(
    fileURLWithPath: "/opt/models/parakeet-tdt-0.6b-v3-coreml",
    isDirectory: true
)

let models = try await AsrModels.load(
    from: repoDirectory,
    configuration: AsrModels.defaultConfiguration(),
    version: .v3
)

let asrManager = AsrManager()
try await asrManager.initialize(models: models)

​
Switching Versions

let englishRepo = URL(fileURLWithPath: "/opt/models/parakeet-tdt-0.6b-v2-coreml")
let englishModels = try await AsrModels.load(from: englishRepo, version: .v2)

​
Troubleshooting

  • Use AsrModels.modelsExist(at:) to verify all bundles are present
  • parakeet_vocab.json must sit beside the model bundles
  • If you see AsrModelsError.modelNotFound, check folder names and coremldata.bin files
