# Model Card for indri-0.1-350m-tts
Indri is a series of audio models that can do TTS, ASR, and audio continuation. This is the medium sized model (350M) in our series and supports TTS tasks in 2 languages:
1. English
2. Hindi
## Model Details
### Model Description
`indri-0.1-350m-tts` is a novel, small, and lightweight TTS model based on the transformer architecture.
It models audio as tokens and can generate high-quality audio with consistent style cloning of the speaker.

### Key features
1. Extremely efficient, based on GPT-2 medium architecture. The methodology can be extended to any autoregressive transformer-based architecture.
2. Ultra-fast. Using our [self hosted service option](#self-hosted-service), the model can achieve speeds up to 400 toks/s (4s of audio generation per s) and under 20ms time to first token on RTX6000Ada NVIDIA GPU.
1. On RTX6000Ada, it can support a batch size of ~500 with full context length of 1024 tokens
3. Supports voice cloning with small prompts (<5s).
4. Code mixing text input in 2 languages - English and Hindi.
### Details
1. Model Type: GPT-2 based language model
2. Size: 350M parameters
3. Language Support: English, Hindi
4. License: CC BY 4.0
## Technical details
Here's a brief of how the model works:
1. Converts input text into tokens
2. Runs autoregressive decoding on GPT-2 based transformer model and generates audio tokens
3. Decodes audio tokens (using [Kyutai/mimi](https://huggingface.co/kyutai/mimi)) to audio
Please read our blog [here](https://www.indrivoice.ai/blog/2024-11-21-building-indri-tts) for more technical details on how it was built.
## How to Get Started with the Model
### ЁЯдЧ pipelines
Use the code below to get started with the model. Pipelines are the best way to get started with the model.
```python
import torch
import torchaudio
from transformers import pipeline
model_id = '11mlabs/indri-0.1-350m-tts'
task = 'indri-tts'
pipe = pipeline(
task,
model=model_id,
device=torch.device('cuda:0'), # Update this based on your hardware,
trust_remote_code=True
)
output = pipe(['Hi, my name is Indri and I like to talk.'])
torchaudio.save('output.wav', output[0]['audio'][0], sample_rate=24000)
```
### Self hosted service
```bash
git clone https://github.com/cmeraki/indri.git
cd indri
pip install -r requirements.txt
# Install ffmpeg (for Mac/Windows, refer here: https://www.ffmpeg.org/download.html)
sudo apt update -y
sudo apt upgrade -y
sudo apt install ffmpeg -y
python -m inference --model_path 11mlabs/indri-0.1-350m-tts --device cuda:0 --port 8000
```
