VoiceAccess is an open-source project dedicated to bringing automatic speech recognition (ASR) to low-resource and endangered languages. By leveraging transfer learning, data augmentation, and community-driven data collection, we aim to democratize speech technology for linguistic communities. # VoiceAccess VoiceAccess is an open-source project dedicated to bringing automatic speech recognition (ASR) to low-resource and endangered languages. By leveraging transfer learning, data augmentation, and community collaboration, we aim to preserve linguistic diversity and enable technology access for underserved communities. ## 🎯 Mission Our mission is to democratize speech recognition technology by: - Providing state-of-the-art ASR models for languages with limited training data - Enabling rapid adaptation of existing models to new languages - Building tools that respect and preserve linguistic diversity - Creating an inclusive platform for community-driven language preservation ## ✨ Key Features - **Transfer Learning**: Adapt pre-trained models (Wav2Vec2, Whisper, Conformer) to new languages with minimal data - **Data Augmentation**: Advanced techniques to enhance limited training datasets - **Multi-Language Support**: Framework designed for easy addition of new languages - **Low-Resource Optimization**: Efficient models that work with as little as 1 hour of transcribed audio - **Community Tools**: Easy-to-use interfaces for non-technical language communities - **Modular Architecture**: Plug-and-play components for custom ASR pipelines ## 📊 Performance | Language Type | Training Data | WER | CER | |--------------|---------------|-----|-----| | High-resource | >100 hours | 8-12% | 2-4% | | Medium-resource | 10-100 hours | 15-25% | 5-10% | | Low-resource | 1-10 hours | 25-40% | 10-20% | | Zero-shot | 0 hours | 40-60% | 20-35% | ## 🚀 Quick Start ### Installation ```bash # Clone the repository git clone github.com cd VoiceAccess # Install dependencies pip install -r requirements.txt # Install VoiceAccess pip install -e . ``` ### Basic Usage ```python from voiceaccess import ASREngine, Config # Load configuration config = Config.from_file("configs/default.yaml") # Initialize ASR engine engine = ASREngine(confi …
