# STT Runner
|
|
|
|
Speech-to-Text transcription using sherpa-onnx + Qwen3-ASR, Text-to-Speech with ZipVoice (zero-shot voice cloning), and LLM/embedding inference with llama.cpp (Granite-4.2 + nomic-embed-text-v1.5).
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
python3 -m venv .venv
|
|
.venv/bin/pip install -r requirements.txt
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Speech-to-Text
|
|
|
|
```bash
|
|
python stt_runner.py [--language=Indonesian] audio1.wav audio2.wav ...
|
|
```
|
|
|
|
### Text-to-Speech
|
|
|
|
```bash
|
|
python tts_runner.py [--output=out.wav] [--ref-audio=ref.wav] [--ref-text="..."] "text to speak"
|
|
```
|
|
|
|
Output defaults to `output.wav`. The reference audio/text (voice to clone) is set in `config/tts.py` and can be overridden per-run with `--ref-audio` / `--ref-text` (the text must match the audio exactly).
|
|
|
|
### LLM Chat (llama.cpp)
|
|
|
|
```bash
|
|
python llm_runner.py "What is the capital of France?" # single prompt
|
|
python llm_runner.py # interactive chat
|
|
```
|
|
|
|
### Embedding (llama.cpp)
|
|
|
|
```bash
|
|
python embed_runner.py "text to embed" "another text"
|
|
python embed_runner.py "What is TSNE?" --prefix "search_query: "
|
|
```
|
|
|
|
## Configuration
|
|
|
|
Model paths and inference parameters are hardcoded in `config/`:
|
|
|
|
- `config/model.py` — model paths (conv_frontend, encoder, decoder, tokenizer under `models/`)
|
|
- `config/asr.py` — inference params: `LANGUAGE`, `HOTWORDS`, `NUM_THREADS`, `PROVIDER`, `SAMPLE_RATE`, `FEATURE_DIM`, `MAX_TOTAL_LEN`, `MAX_NEW_TOKENS`
|
|
- `config/tts.py` — TTS model paths, `REFERENCE_AUDIO`, `REFERENCE_TEXT`, `OUTPUT_FILE`, `NUM_THREADS`, `PROVIDER`, `NUM_STEPS`
|
|
- `config/llm.py` — Granite-4.2 model path, `N_CTX`, `N_THREADS`, `N_GPU_LAYERS`, `MAX_TOKENS`, `TEMPERATURE`, `TOP_P`, `TOP_K`, `SYSTEM_PROMPT`, `CHAT_TEMPLATE`
|
|
- `config/embed.py` — nomic-embed-text-v1.5 model path, `N_CTX`, `N_THREADS`, `PREFIX_QUERY`, `PREFIX_DOCUMENT`, `DEFAULT_PREFIX`
|
|
|
|
`LANGUAGE` defaults to `""` (all languages / auto-detect). Passing `--language` on the CLI overrides it.
