| # Speech Portuguese (Brazilian) Accent Classifier |
|
|
| 🎙️🤖🇧🇷 |
|
|
| This project is a speech accent classifier that distinguishes between Portuguese (Brazilian) and other accents. |
|
|
| ## Project Overview |
|
|
| This application uses a trained model to classify speech accents into two categories: |
| 1. Portuguese (Brazilian) |
| 2. Other |
|
|
| The model is based on the author's work [results] and utilizes the Portuguese portion of the Common Voice dataset (version 11.0) from Mozilla Foundation. |
|
|
| ## Dataset |
|
|
| The project uses the Portuguese subset of the Common Voice dataset: |
| - Dataset: "mozilla-foundation/common_voice_11_0", "pt" |
| |
| Brazilian accents included in the dataset: |
| - Português do Brasil, Região Sul do Brasil |
| - Paulistano |
| - Paulista, Brasileiro |
| - Carioca |
| - Mato Grosso |
| - Mineiro |
| - Interior Paulista |
| - Gaúcho |
| - Nordestino |
| - And various regional mixes |
| |
| ## Model and Processor |
| |
| The project utilizes the following model and processor: |
| - Base Model: "facebook/wav2vec2-base-960h" |
| - Processor: Wav2Vec2Processor.from_pretrained |
|
|
| ## Model Versions |
|
|
| Was trained three versions of the model with different configurations: |
|
|
| 1. **(OLD) v 1.1**: |
| - Epochs: 3 |
| - Training samples: 1000 |
| - Validation samples: 200 |
|
|
| 2. **(OLD) v 1.2**: |
| - Epochs: 10 |
| - Training samples: 1000 |
| - Validation samples: 500 |
|
|
| 3. **(NEW) v 1.3**: |
| - Epochs: 20 |
| - Training samples: 5000 |
| - Validation samples: 1000 |
|
|
| All models were trained using high RAM GPU on Google Colab Pro. |
|
|
| ## Model Structure (files) |
|
|
| Each version of the model includes the following files: |
| results config.json | preprocessor_config.json | model.safetensors | special_tokens_map.json | tokenizer_config.json | vocab.json |
|
|
|
|
| ## How to Use |
|
|
| Test with recording or uploading an audio file. To test, I recommend short sentences. |
