🍎📱🎙️ Shenava Koochik 1.0 — Core ML streaming for iOS 15

Cache-aware FP16 Core ML NeuralNetwork export for Apple devices that cannot use the newer ML Program package. It uses Core ML specification version 5, has iOS 14/macOS 11 availability, and is designed to compile and run on iOS 15.

🌊 Streaming contract

Each call produces one CTC step from a 170 ms feature window and returns the caches for the next call.

Inputs:

• processed_signal: FP32 [1, 80, 17]
• cache_last_channel: FP32 [17, 1, 70, 512]
• cache_last_time: FP32 [17, 1, 512, 8]

Outputs:

• logits: FP32 [1, 1, 1025]
• cache_last_channel_next: FP32 [17, 1, 70, 512]
• cache_last_time_next: FP32 [17, 1, 512, 8]

The graph uses 9 frames of pre-encode cache plus an 8-frame chunk, 17 conformer layers, and a constant channel-cache length of 70. Initialize both caches to zero and thread each *_next output into the next call.

📦 Files

• *_ios15_fp16.mlmodel: 212 MB NeuralNetwork model.
• *_manifest.json: authoritative streaming shapes and export provenance.
• tokens.json, mel_filters_slaney_80x257.json, preprocessor.json: tokenizer/feature assets.
• export_koochik10_streaming_coreml.py: reproducible exporter.

For the streaming graph, treat shenava_koochik_1_0_ctc_streaming_att70_0_ios15_fp16_manifest.json and the export script as authoritative. The fixed-window fields retained in preprocessor.json describe the shared feature pipeline, not this graph’s 17-frame tensor contract.

Published FP16-versus-FP32 argmax agreement: 1.000.

🇮🇷 خلاصهٔ فارسی

این نسخه برای اجرای جریانی روی iOS 15 و دستگاه‌های قدیمی‌تر اپل ساخته شده است. در هر فراخوانی ۱۷۰ میلی‌ثانیه پردازش می‌شود و cacheهای خروجی باید به فراخوانی بعدی داده شوند. قرارداد دقیق tensorها در فایل manifest قرار دارد.
