Indic-Mio-MLX-fp16

Apple Silicon fp16 export of SPRINGLab/Indic-Mio, bundled with the MioCodec 25 Hz / 24 kHz companion required to decode Indic-Mio content tokens into waveform audio.

This is an artifact bundle for Swift/MLX runtime work. It preserves upstream key names; runtime code is expected to implement model loading, sampling, MioCodec conditioning, and waveform decoding.

Validation

Test	Result
Indic-Mio + MioCodec local roundtrip	Passed
Input text	नमस्ते, मैं आज बहुत खुश हूँ। <happy>
ASR transcript	नमस्ते, मैं आज बहुत खुश हूँ
Sample rate	24000 Hz

The roundtrip test was a local synthesis and transcription sanity check. It verifies that the exported Indic-Mio weights and bundled MioCodec path can produce intelligible Hindi speech for an explicit emotion marker. It is not a full runtime benchmark.

Usage

These artifacts are not a drop-in Transformers checkpoint. They are intended for speech-swift or another MLX runtime that implements the Indic-Mio token generation path and MioCodec decoding path.
