Qwen3-ASR 0.6B CoreML

Core ML conversion of Qwen/Qwen3-ASR-0.6B for on-device speech recognition on Apple platforms (iOS/macOS).

Model Variants

Features

• 30+ languages including English, Chinese, Japanese, Korean, and more
• On-device inference - no internet required
• Autoregressive decoder with KV-cache support
• Processes audio in 1-second chunks (100 mel frames)

Benchmarks (M4 Pro)

Official PyTorch model: 2.11% WER on LibriSpeech test-clean

Usage with FluidAudio

import FluidAudio

let manager = Qwen3AsrManager()
try await manager.loadModels()

let samples = try AudioConverter().resampleAudioFile(path: "audio.wav")
let transcript = try await manager.transcribe(
    audioSamples: samples,
    language: "en",
    maxNewTokens: 512
)
print(transcript)

Model Architecture

• Encoder: Audio encoder (Whisper-style mel spectrogram input)
• Decoder: 28-layer transformer decoder with 1024 hidden size
• Tokenizer: Qwen tokenizer with special ASR tokens
