# Generate Command Documentation
The `generate` command allows you to generate speech from text directly from the command line using Kyutai Pocket TTS.
## Basic Usage
```bash
uvx pocket-tts generate
# or if installed manually:
pocket-tts generate
```
This will generate a WAV file `./tts_output.wav` with the default text and voice.
## Command Options
### Core Options
- `--text TEXT`: Text to generate (default: "Hello world! I am Kyutai Pocket TTS. I'm fast enough to run on small CPUs. I hope you'll like me.")
- `--voice VOICE`: Path to audio conditioning file (voice to clone) (default: "hf://kyutai/tts-voices/alba-mackenna/casual.wav"). Urls and local paths are supported.
- `--output-path OUTPUT_PATH`: Output path for generated audio (default: "./tts_output.wav")
### Generation Parameters
- `--variant VARIANT`: Model signature (default: "b6369a24")
- `--lsd-decode-steps LSD_DECODE_STEPS`: Number of generation steps (default: 1)
- `--temperature TEMPERATURE`: Temperature for generation (default: 0.7)
- `--noise-clamp NOISE_CLAMP`: Noise clamp value (default: None)
- `--eos-threshold EOS_THRESHOLD`: EOS threshold (default: -4.0)
- `--frames-after-eos FRAMES_AFTER_EOS`: Number of frames to generate after EOS (default: None, auto-calculated based on the text length). Each frame is 80ms.
### Performance Options
- `--device DEVICE`: Device to use (default: "cpu", you may not get a speedup by using a gpu since it's a small model)
- `--quiet`, `-q`: Disable logging output
## Examples
### Basic Generation
```bash
# Generate with default settings
pocket-tts generate
# Custom text
pocket-tts generate --text "Hello, this is a custom message."
# Custom output path
pocket-tts generate --output-path "./my_audio.wav"
```
### Voice Selection
```bash
# Use different voice from HuggingFace
pocket-tts generate --voice "hf://kyutai/tts-voices/jessica-jian/casual.wav"
# Use local voice file
pocket-tts generate --voice "./my_voice.wav"
```
### Quality Tuning
```bash
# Higher quality (more steps)
pocket-tts generate --lsd-decode-steps 5 --temperature 0.5
# More expressive (higher temperature)
pocket-tts generate --temperature 1.0
# Adjust EOS threshold, smaller means finishing earlier.
pocket-tts generate --eos-threshold -3.0
```
## Output Format
The generate command always outputs WAV files in the following format:
- **Sample Rate**: 24kHz
- **Channels**: Mono
- **Bit Depth**: 16-bit PCM
- **Format**: Standard WAV file
For more advanced usage, see the [Python API documentation](python-api.md) or consider using the [serve command](serve.md) for web-based generation and quick iteration.

# Python API Documentation
Kyutai Pocket TTS provides a Python API for integrating text-to-speech capabilities into your applications.
## Installation
```bash
pip install pocket-tts
```
## Quick Start
```python
from pocket_tts import TTSModel
import scipy.io.wavfile
# Load the model
tts_model = TTSModel.load_model()
# Get voice state from an audio file
voice_state = tts_model.get_state_for_audio_prompt(
"hf://kyutai/tts-voices/alba-mackenna/casual.wav"
)
# Generate audio
audio = tts_model.generate_audio(voice_state, "Hello world, this is a test.")
# Save to file
scipy.io.wavfile.write("output.wav", tts_model.sample_rate, audio.numpy())
```
## Core Classes
### TTSModel

```
#### Properties
##### `device` (str)
Returns the device type where the model is running ("cpu" or "cuda").
By default, the model runs on CPU.
```python
from pocket_tts import TTSModel
model = TTSModel.load_model()
print(f"Model running on: {model.device}")
```
##### `sample_rate` (int)
Returns the generated audio sample rate (typically 24000 Hz).
```python
from pocket_tts import TTSModel
model = TTSModel.load_model()
print(f"Sample rate: {model.sample_rate} Hz")
```
#### Methods
##### `get_state_for_audio_prompt(audio_conditioning, truncate=False)`
Extract model state for a given audio file or URL (voice cloning).
**Parameters:**
- `audio_conditioning` (Path | str | torch.Tensor): Audio file path, URL, or tensor
- `truncate` (bool): Whether to truncate the audio (default: False)
**Returns:**
- `dict`: Model state dictionary containing hidden states and positional information
**Example:**
```python
from pocket_tts import TTSModel
model = TTSModel.load_model()
# From HuggingFace URL
voice_state = model.get_state_for_audio_prompt("hf://kyutai/tts-voices/alba-mackenna/casual.wav")
# From local file
voice_state = model.get_state_for_audio_prompt("./my_voice.wav")
# From HTTP URL
voice_state = model.get_state_for_audio_prompt(
"https://huggingface.co/kyutai/tts-voices/resolve"
"/main/expresso/ex01-ex02_default_001_channel1_168s.wav"

from pocket_tts import TTSModel
model = TTSModel.load_model()
voice_state = model.get_state_for_audio_prompt("hf://kyutai/tts-voices/alba-mackenna/casual.wav")
# Stream generation
for chunk in model.generate_audio_stream(voice_state, "Long text content..."):
# Process each chunk as it's generated
print(f"Generated chunk: {chunk.shape[0]} samples")
# Could save chunks to file or play in real-time
```
## Advanced Usage
### Voice Management
```python
from pocket_tts import TTSModel
model = TTSModel.load_model()
# Preload multiple voices
voices = {
"casual": model.get_state_for_audio_prompt("hf://kyutai/tts-voices/alba-mackenna/casual.wav"),
"funny": model.get_state_for_audio_prompt(
"https://huggingface.co/kyutai/tts-voices/resolve/main/expresso/ex01-ex02_default_001_channel1_168s.wav"
),
}
# Generate with different voices
casual_audio = model.generate_audio(voices["casual"], "Hey there!")
funny_audio = model.generate_audio(voices["funny"], "Good morning.")
```
### Batch Processing
```python
from pocket_tts import TTSModel
import scipy.io.wavfile
import torch
model = TTSModel.load_model()
voice_state = model.get_state_for_audio_prompt("hf://kyutai/tts-voices/alba-mackenna/casual.wav")
# Process multiple texts efficiently by re-using the same voice state
texts = [
"First sentence to generate.",
"Second sentence to generate.",
"Third sentence to generate.",
]
audios = []
for text in texts:
audio = model.generate_audio(voice_state, text)
audios.append(audio)
# Concatenate all audio
full_audio = torch.cat(audios, dim=0)
scipy.io.wavfile.write("batch_output.wav", model.sample_rate, full_audio.numpy())
```
### Streaming to File
You can refer to our CLI implementation which can stream audio to a wav file.
For more information about the command-line interface, see the [Generate Documentation](generate.md) or [Serve Documentation](serve.md).
