# Grapheme to Phoneme (G2P) with Stress

This project provides a Grapheme to Phoneme (G2P) conversion tool that first checks the CMU Pronouncing Dictionary for phoneme translations. If a word is not found in the dictionary, it utilizes two Transformer-based models to generate phoneme translations and add stress markers. The output is in ARPAbet format, and the model can also convert graphemes into phoneme integer indices.

## Features

1. **CMU Pronouncing Dictionary Integration**: First checks the CMU dictionary for phoneme translations.
2. **Transformer-Based Conversion**:
    - **Phoneme Generation**: The first Transformer model converts graphemes into phonemes.
    - **Stress Addition**: The second Transformer model adds stress markers to the phonemes.
3. **ARPAbet Output**: Outputs phonemes in ARPAbet format.
4. **Phoneme Integer Indices**: Converts graphemes to phoneme integer indices.
5. A BPE tokenizer was used, which led to a better translation quality

## Installation

1. Clone the repository:
    ```sh
    git clone https://github.com/NikiPshg/Grapheme-to-Phoneme-G2P-with-Stress.git
    cd Grapheme-to-Phoneme-G2P-with-Stress
    ```

2. Install the required dependencies:
    ```sh
    pip install -r requiremenst.txt
    ```


### Example

```python
from G2P_lexicon import g2p_en_lexicon

# Initialize the G2P converter
g2p = g2p_en_lexicon()
# Convert a word to phonemes
text = "text, numbers, and some strange symbols !№;% 21"
phonemes = g2p(text, with_stress=False)
