africanwhisper 0.9.21

A framework for fast fine-tuning and API endpoint deployment of Whisper model specifically developed to accelerate Automatic Speech Recognition(ASR) for African Languages.

African Whisper: ASR for African Languages

Framework for seamless fine-tuning and deploying Whisper Model developed to advance Automatic Speech Recognition (ASR): translation and transcription capabilities for African languages.

Features

• 🔧 Fine-Tuning: Fine-tune the Whisper model on any audio dataset from Huggingface, e.g., Mozilla's Common Voice, Fleurs, LibriSpeech, or your own custom private/public dataset etc

• 📊 Metrics Monitoring: View training run metrics on Wandb.

• 🐳 Production Deployment: Seamlessly containerize and deploy the model inference endpoint for real-world applications.

• 🚀 Model Optimization: Utilize CTranslate2 for efficient model optimization, ensuring faster inference times.

• 📝 Word-Level Transcriptions: Produce detailed word-level transcriptions and translations, complete with timestamps.

• 🎙️ Multi-Speaker Diarization: Perform speaker identification and separation in multi-speaker audio using diarization techniques.

• 🔍 Alignment Precision: Improve transcription and translation accuracy by aligning outputs with Wav2vec models.

• 🛡️ Reduced Hallucination: Leverage Voice Activity Detection (VAD) to minimize hallucination and improve transcription clarity.

The framework implements the following papers:

1. Robust Speech Recognition via Large-Scale Weak Supervision : Speech processing systems trained to predict large amounts of transcripts of audio on the internet scaled to 680,000 hours of multilingual and multitask supervision.

2. WhisperX: Time-Accurate Speech Transcription of Long-Form Audio for time-accurate speech recognition with word-level timestamps.

3. Pyannote.audio: Neural building blocks for speaker diarization for advanced speaker diarization capabilities.

4. Efficient and High-Quality Neural Machine Translation with OpenNMT: Efficient neural machine translation and model acceleration.

For more details, you can refer to the Whisper ASR model paper.
