| # Go2 dock models |
|
|
| Estonian speech models that Meridein's Unitree Go2 EDU docks run: the |
| voices (Pocket TTS, Piper) and speech recognition (Whisper). All are |
| derived from public models, converted or packed for the dock's Jetson. A dock downloads them at a |
| pinned commit and checks each file's sha256 before using it. |
|
|
| **Files are never overwritten here.** A new version gets a new file name, so |
| a release that pins a commit and a sha256 keeps working. |
|
|
| | file | what | size | sha256 | |
| |---|---|---|---| |
| | `pocket-cpp-et.tar.gz` | Pocket TTS, Estonian, as ONNX for PocketTTS.cpp (one folder, `pocket-cpp-et/`) | 436 064 256 | `1cf3ae8b3eab0724a023a8e5852272e0a870fccbd5fe7bc61a48940a680cd3ca` | |
| | `ggml-whisper-large-v3-turbo-et-verbatim-2604-q5_0.bin` | Whisper large-v3-turbo, Estonian, q5_0 for whisper.cpp | 574 041 195 | `ec401581b6ac1788b4eff8b92c5257a65bf24b50be1e488387fd9760166a1ad7` | |
| | `vits-piper-et_EE-news-medium.tar.gz` | Piper's Estonian news voice (four speakers) for sherpa-onnx (one folder, `vits-piper-et_EE-news-medium/`) | 80 299 072 | `55ef843f59f38a67d6acf5c6b9c62a913516784c6f529ae1c92359f61a45d927` | |
| |
| ## `pocket-cpp-et.tar.gz`: Pocket TTS, Estonian (ONNX) |
| |
| - **Run by** [PocketTTS.cpp](https://github.com/VolgaGerm/PocketTTS.cpp) at |
| `e801e7d`, with `--precision int8`. The int8 set is what runs; the fp32 |
| files are kept beside it. |
| - **Made from** [cbentes/pocket-tts-estonian](https://huggingface.co/cbentes/pocket-tts-estonian): |
| the weights and tokenizer at `e8d2fd9cc01ae6e4e505269adcc1d9bdaecbea0f`, |
| the config and the six voice clips at |
| `b37e49dd65514fb79a05cff2ace696e24af15d66`. Exported with pocket-tts |
| 2.1.0 and PocketTTS.cpp's `export_onnx.py` at `e801e7d`; the |
| beginning-of-sequence before the voice is in `mimi_encoder.onnx`. |
| `export_info.json` inside records the same. |
| - **Licence:** CC BY-SA 4.0, as the weights it is made from, which were |
| trained on the TalTech Estonian Speech Dataset 1.0. Credit: |
| cbentes/pocket-tts-estonian and TalTech. Changes: converted to ONNX and |
| quantised to int8. Share-alike: this derivative is under the same licence. |
|
|
| ## `ggml-whisper-large-v3-turbo-et-verbatim-2604-q5_0.bin`: Whisper, Estonian |
| |
| - **Run by** `whisper-server` ([whisper.cpp](https://github.com/ggml-org/whisper.cpp)), |
| language `et`. |
| - **Made from** [TalTechNLP/whisper-large-v3-turbo-et-verbatim-2604](https://huggingface.co/TalTechNLP/whisper-large-v3-turbo-et-verbatim-2604), |
| its ggml model (`ggml/ggml-model.bin`, sha256 `4e231f931f029850d7ca497efe4223f85c495a27d986d955f9a577ac1cd02edb`), |
| quantised to `q5_0` with whisper.cpp's quantize tool (whisper.cpp |
| `60c0be6`). The quantised model needs about 1 GB less memory. |
| - **Licence:** that of TalTechNLP's model, which this file is derived from. |
| See their model card; credit: TalTech (Tallinn University of Technology). |
| The repository's `cc-by-sa-4.0` tag is the Pocket model's. |
|
|
| ## `vits-piper-et_EE-news-medium.tar.gz`: Piper, Estonian |
| |
| - **Run by** [sherpa-onnx](https://github.com/k2-fsa/sherpa-onnx)'s VITS |
| engine; speakers Albert 0, Kalev 1, Mari 2, Vesta 3. |
| - **Made from** [rhasspy/piper-voices](https://huggingface.co/rhasspy/piper-voices) |
| at `e7229f7d33a10e145e109b886d661984201ac3c4`, `et/et_EE/news/medium/`: |
| sherpa-onnx's metadata written into the `.onnx`, `tokens.txt` from the |
| `.onnx.json` (the five two-letter vowels left out: unused without |
| `vowel_clusters`), and the espeak-ng data from sherpa-onnx's |
| `vits-piper-en_US-lessac-medium` package (it includes Estonian). |
| Rebuilt the same, byte for byte, by `tools/models/piper_et.sh` in |
| unitree-go2-dev. |
| - **Licence:** the voice's dataset is CC BY (the Speech Corpus of Estonian |
| News Sentences, META-SHARE "Available - Unrestricted Use"; see |
| `MODEL_CARD` inside). The espeak-ng data is espeak-ng's, GPL-3.0. |
