TOPIC : Speech Denoising

Description

This internship offers the opportunity to contribute to R&D on advanced AI Speech Denoising initiative aimed at improving speech clarity in real-world, noisy environments. The intern would combine deep learning, digital signal processing, and data-driven optimization to build robust models capable of separating human speech from complex background noise. The initial focus would be on specializing and fine-tuning state-of-the-art noise suppression AI models to achieve optimal denoising performance in selected acoustic environments.

Responsibilities:

  • Data Collection & Preparation
  • a) Collect, annotate, and preprocess speech and noise datasets from various environments.
  • b) Implement scripts for mixing speech and environmental noise at different signal-to-noise ratios (SNRs) and perform quality control on generated data.
  • Machine Learning Development
  • a) Assist in training and fine-tuning deep learning models for speech denoising.
  • b) Evaluate models using objective metrics (e.g., PESQ, STOI) and subjective listening tests.
  • c) Experiment with architecture variations, training configurations, and hyperparameter tuning.
  • System Integration & Evaluation
  • a) Conduct performance benchmarking and error analysis.
  • b) Document results, visualize findings, and present outcomes to the research team.


Requirements:

  • Education: Currently pursuing or recently completed a Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related technical discipline.
  • Programming: Proficient in Python, with experience in NumPy, pandas, and preferably PyTorch.
  • Machine Learning Knowledge: Familiar with deep learning fundamentals and general model training workflows.


Expected Outcomes

  • Hands-on experience building and evaluating state-of-the-art speech denoising systems.
  • Exposure to end-to-end AI development, from data acquisition to deployment.
  • Mentorship from researchers and engineers experienced in audio AI, deep learning, and signal processing.
  • A practical understanding of how AI models integrate into real-world audio pipelines.


Commitment:

  • Able to commit on a full-time basis for ideally 6 months (or a minimum of 5 months) from Jan 2026.


At Thales, we’re committed to fostering a workplace where respect, trust, collaboration, and passion drive everything we do. Here, you’ll feel empowered to bring your best self, thrive in a supportive culture, and love the work you do. Join us, and be part of a team reimagining technology to create solutions that truly make a difference – for a safer, greener, and more inclusive world.
