Roles and Responsibilities – Data Science Engineer Intern (AI/ASR Models)
Design and develop Automatic Speech Recognition (ASR) systems using state-of-the-art AI and deep learning techniques.
Train and fine-tune pre-trained ASR models (e.g., OpenAI Whisper, Wav2Vec, DeepSpeech) on domain-specific datasets for improved accuracy and performance.
Perform data preprocessing, including audio segmentation, noise reduction, and transcript alignment for ASR training.
Implement custom pipelines for audio feature extraction (MFCCs, spectrograms) and model input formatting.
Evaluate model performance using standard metrics such as Word Error Rate (WER), Character Error Rate (CER), and accuracy.
Optimize model inference for real-time or near real-time transcription use-cases.
Conduct experiments with model architectures, hyperparameter tuning, and transfer learning techniques.
Document development processes, model experiments, and performance benchmarks.
Collaborate with the AI research and engineering team to integrate ASR models into production systems or applications.
Stay updated with the latest research and advancements in ASR, speech processing, and machine learning.
