The Learni story
Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1VAD Fundamentals: Acoustic Principles and Audio Signals (MFCC Features, Spectrograms)
Dive into the basics of sound and Voice Activity Detection, explore audio features like MFCC and spectrograms with Python and Librosa, analyze vocal signals vs noise through interactive exercises, create simple datasets to test detection, conduct first tests on real company recordings, produce a preliminary analysis report that immediately boosts your professional skills.
Module 2VAD Algorithms: Energy Thresholds and Zero-Crossing (Python Tools, Visualizations)
Discover classic VAD algorithms like energy detection and zero-crossing rate, implement them step by step in Python with NumPy and Matplotlib to visualize results, test on concrete cases of noisy virtual meetings, fine-tune adaptive thresholds during practical workshops, generate performance logs to evaluate accuracy, transform this knowledge into assets for your business audio projects.
Module 3Open-Source VAD Tools: WebRTC VAD and py-webrtcvad (Real-Time Python Integration)
Get hands-on with WebRTC VAD and py-webrtcvad for robust real-time voice detection, install and configure the libraries in a guided session, develop a live audio streaming script with USB microphones, test on enterprise VoIP call scenarios, optimize aggressiveness modes for different ambient noises, produce a functional prototype ready to integrate into your professional applications.
Module 4Advanced VAD Introduction: Silero VAD and Lightweight ML Models (Torch, ONNX)
Explore Silero VAD based on deep learning for superior accuracy, integrate it with PyTorch and export to ONNX for lightweight deployment, train on public vocal datasets via supervised exercises, apply to real cases like enterprise voice assistants, measure latency and false positives on various hardware, finalize a customizable VAD module that elevates your certified audio AI skills.
Module 5VAD Projects: ASR Integration and Deployment (Pipelines, Docker, Evaluation)
Build an ongoing project integrating VAD into an ASR pipeline with Whisper or Vosk, containerize in Docker for easy deployment, test in real enterprise conditions like conferences or voice chatbots, evaluate ROC metrics and real-time accuracy, prepare complete documentation and an optimization plan, leave with a concrete portfolio highlighting your professional Voice Activity Detection training.
Evaluation method

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
