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.
