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 signals (Python, SciPy, spectrograms)
Discover the basics of Voice Activity Detection through spectral analysis of audio signals, using Python and SciPy to extract features like energy and zero-crossings. Complete practical exercises on real datasets to identify voice vs. silence, produce your first simple detection scripts, test in simulated noisy conditions, and validate essential performance metrics for an immersive professional training.
Module 2Classic VAD Algorithms: G.729, WebRTC (hybrid OpenCV implementation, adaptive thresholds)
Dive into VAD standards like G.729 and WebRTC VAD, implement them in Python with dynamic thresholds and filtering, integrate OpenCV for hybrid speaker visual detection, perform hands-on exercises on varied audio, optimize parameters to minimize false positives, generate accuracy reports, and apply to real-world enterprise voice assistant cases.
Module 3Deep Learning VAD: RNN, CNN (TensorFlow, PyTorch, LibriSpeech datasets)
Master deep learning approaches for Voice Activity Detection with recurrent and convolutional networks, train models on LibriSpeech using TensorFlow and PyTorch, code custom architectures for real-time detection, test on real noise with data augmentation, evaluate via ROC curves and F1-scores, deploy functional prototypes, and integrate with multimodal streams using OpenCV for advanced skills.
Module 4Real-Time VAD Optimization: embeddings, low-latency (ONNX, edge computing, vocal OCR)
Optimize your VAD models for real-time deployment by converting to ONNX, implement on edge devices with low latency, fuse with OCR and visual detection via OpenCV for multimodal applications, conduct benchmarks on varied hardware, fine-tune hyperparameters for robustness, produce deployable deliverables, and simulate industrial scenarios like conferences or vocal IoT.
Module 5Advanced 2026 VAD Projects: complete pipelines (ASR integration, skills certification)
Build end-to-end VAD pipelines integrating ASR and computer vision, develop a capstone project on multi-speaker detection for 2026, test in real conditions with group feedback, optimize for enterprise production, generate certified portfolios, review best practices, and prepare for cloud or on-premise deployment for a comprehensive professional training.
Evaluation method
- Interactive quizzes and MCQs on VAD algorithms daily
- Practical projects evaluated by certified experts
- Real case studies with performance metrics (F1-score, latency)
Learning method
- Active pedagogy with 70% hands-on practice on real code
- Individualized support in small groups of max 10
- Post-training resources: source codes, video tutorials
- Qualiopi certification validating intermediate VAD skills
Methods, materials and delivery
The Training Voice Activity Detection (VAD) - Implementing Advanced Voice Detection program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.
Equipment required
For the smooth delivery of the Training Voice Activity Detection (VAD) - Implementing Advanced Voice Detection program, the following equipment is required:
- Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
- Training environments installed on workstations or accessible online
- Course materials, hands-on exercises and complementary resources
- Post-training access to materials and educational resources
For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.
* contact us for remote delivery feasibility** ratio varies depending on the program
Skills assessment methods
Assessment of skills acquired during the Training Voice Activity Detection (VAD) - Implementing Advanced Voice Detection program is performed through:
- During training: case studies, hands-on labs and professional scenarios
- End of training: self-assessment questionnaire and skills evaluation by the trainer
- After training: completion certificate detailing acquired skills
Program accessibility
Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.
Enrollment terms and lead times
Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

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.
