| # Piper en_US-lessac-medium (RLX staging) |
| |
| Piper ONNX voice + RLX `rlx-split/` subgraphs. |
| |
| | Field | Value | |
| |---|---| |
| | **Hub id** | [`eugenehp/piper`](https://huggingface.co/eugenehp/piper) | |
| | **Kind** | Converted / re-laid-out for RLX from an upstream checkpoint. | |
| | **RLX crate** | [`rlx-piper`](https://github.com/MIT-RLX/rlx-models/tree/main/crates/rlx-piper) | |
| | **Upstream** | https://huggingface.co/rhasspy/piper-voices | |
| |
| ## Quick start |
| |
| ```bash |
| hf download eugenehp/piper --local-dir . |
| cargo run -p rlx-piper --release -- --dir . |
| ``` |
| |
| ## File highlights |
| |
| - `en_US-lessac-medium.onnx` (60.3 MiB) |
| - `piper.f16.gguf` (58.7 MiB) |
| - `rlx-split/flow_dec.onnx` (33.5 MiB) |
| - `rlx-split/enc_p.onnx` (24.4 MiB) |
| - `rlx-split/dp_manifest.json` (14.8 KiB) |
| - `en_US-lessac-medium.onnx.json` (4.8 KiB) |
|
|
| ## Do not use as the main runtime pack |
|
|
| These files may be present for historical / staging reasons but are **not** the supported RLX load path: |
|
|
| - `piper.f16.gguf` |
|
|
| Community `*.f16.gguf` / LM-only Q4 packs are format wraps — they are not drop-in replacements for the RLX primary file above. |
|
|
| ## Run with RLX |
|
|
| Clone [rlx-models](https://github.com/MIT-RLX/rlx-models), place this repo under `weights/tts/piper` (or pass the path explicitly), then: |
|
|
| ```bash |
| cargo run -p rlx-piper --release -- --dir . |
| ``` |
