## Model Overview

This model provides neural text-to-speech synthesis for Bambara (Bamanankan), the most widely spoken language in Mali. The model supports 10 authentic Bambara speakers and produces high-fidelity audio without requiring separate vocoder models. It serves over 14 million Bambara speakers across West Africa with native-level pronunciation and cultural authenticity.

<!-- - Try our live demo on [Hugging Face Spaces](https://huggingface.co/spaces/MALIBA-AI/BambaraText2Speech) -->
- **Available Speakers:** Adama, Moussa, Bourama, Modibo, Seydou, Amadou, Bakary, Ngolo, Ibrahima, Amara


## Quick Start

### Installation


<!-- ```bash
  pip install maliba-ai==1.1.1b0
``` -->

<!-- For development installations: -->

```bash
pip install git+https://github.com/MALIBA-AI/bambara-tts.git
```
with uv (faster)

<!-- ```bash
    uv pip install maliba-ai==1.1.1b0
``` -->

```bash
    uv pip install git+https://github.com/MALIBA-AI/bambara-tts.git
```
Note : if you are in colab  please install those additional dependencies : 

```
    !pip install --no-deps bitsandbytes accelerate xformers==0.0.29.post3 peft trl triton cut_cross_entropy unsloth_zoo
    !pip install sentencepiece protobuf huggingface_hub hf_transfer
    !pip install --no-deps unsloth
```

### Basic Usage

```python
from maliba_ai.tts.inference import BambaraTTSInference
from maliba_ai.config.settings import Speakers

tts = BambaraTTSInference()

text = "Aw ni ce. I ka kɛnɛ wa?"  
audio = tts.generate_speech(text=text, speaker_id=Speakers.Bourama, output_filename="greeting.wav")

```

## Technical Specifications

### Architecture
- **Base Model**: Spark-TTS (LLM-based TTS)
- **Foundation**: Qwen2.5-based language model
- **Parameters**: ~500M
- **Audio Format**: 16kHz, 16-bit PCM mono
- **Language Support**: Bambara (bm-ML)


## Model Input/Output

### Input
- **Text**: Bambara text in standard orthography
- **Speaker ID**: Choice of 10 available speakers
- **Parameters**: Temperature, top-k, top-p (optional)

### Output
- **Audio**: 16kHz mono WAV format
- **Quality**: Professional-grade speech synthesis

## ⚠️ Known Limitations

### Language Mixing
- **Issue**: Poor performance with French-Bambara code-switching
- **Recommendation**: Use pure Bambara text for optimal results

### Numeric Content
- **Issue**: Suboptimal handling of Arabic numerals (1, 2, 3...)
- **Recommendation**: Convert numbers to written Bambara words

## ⚠️ Disclaimer

This model provides high-fidelity Bambara speech synthesis intended for research, education, and community applications. The following uses are **strictly forbidden**:
