About Alexandre Caulier

I'm working at Sonos, Inc as a Senior Machine Learning Scientist/Engineer in the Spoken Language Understanding team of the Sonos Voice Control branch where is developed Sonos’ voice assistant. This team owns many Machine Learning models training (python) and inference (rust) pipelines. I am the main contributor to many important model improvements shipped in production over the years ranging from Speech Recognition, Natural Language Understanding and Directedness Classification. I am leading many R&D projects in that team where I define the roadmaps, supervise several less experienced colleagues, review the Pull Requests and contribute personally to the codebase. I also take care of cross-team cooperation in order to ensure that new features land where they should. I am always motivated to expand my scope which led to me work on other part of the stack as well. Finally, I take part in several reports and presentations rituals in order to have a good knowledge sharing in the department.Prior to its acquisition, I worked at Snips where my main focus was training and running Automatic Speech Recognition models that were small enough and quick enough to run in real-time on tiny devices like a Raspberry Pi 3.As a result, I have several years of experience in Automatic Speech Recognition and Language Modeling.I graduated from ENSIMAG where I studied Computer Science and Applied Mathematics and during this time, I had the chance to do an ERASMUS exchange at NTNU in Norway where I specialized in Deep Reinforcement Learning.Also, during my free time I take part in a lot of coding, algorithmic, optimization and data science contests which allowed me to discover several fields and tools.

Listed skills include Keras, C, Python, Tensorflow, and 8 others.

I joined as an intern in the Speech team. The focus of the team was to develop a Speech Recognition engine working on real time on a tiny device like a Raspberry Pi 3.I got my hands on TensorFlow and Kaldi to develop those models. Plus I developed the pipeline allowing to personalize the Language Model of the Speech Recognition engine. This pipeline was used to train the model that we shipped in production just before the end of my internship.
