Meet the Alexa team at Interspeech!

The Alexa Machine Learning team looks forward to meeting you at Interspeech 2017! Come and visit our booth to learn more about our research and career opportunities. For an overview of the conference, click here. Read on for more information about our technology and team.

What is Alexa?

Amazon Alexa is leading the way in making spoken language the next user interface paradigm. Alexa is the voice service that powers Amazon’s family of Echo productsAmazon Fire TV, and other third party products. Echo is a device that you can talk to from across the room to play music, get the news, control lights and your thermostat and more.

Technologies We Focus On

The Alexa Science and Machine Learning team made the magic of Alexa possible, but that was just the beginning. Our goal is to make voice interfaces ubiquitous and as natural as speaking to a human. We have a relentless focus on the customer experience and customer feedback. We use many real-world data sources including customer interactions and a variety of techniques like highly scalable deep learning. Learning at this massive scale requires new research and development. The team is responsible for cutting-edge research and development in virtually all fields of Human Language Technology: Automatic Speech Recognition (ASR), Artificial Intelligence (AI), Natural Language Understanding (NLU), Question Answering, Dialog Management, and Text-to-Speech (TTS). See an interview with VP Rohit Prasad here

Alexa Scientists and Developers have large-scale impact on customer’s lives and on the industry-wide shift to voice user interfaces. Scientists and engineers in the Alexa team also invent new tools and APIs to accelerate development of voice services by empowering developers through the Alexa Skills Kit and the Alexa Voice Service. For example, developers can now create a new voice experience by simply providing a few sample sentences.

Alexa Research

We also look outward. Your discoveries in speech recognition, natural language understanding, deep learning, and other disciplines of machine learning can fuel new ideas and applications that have direct impact on peoples’ lives. We firmly believe that our team must engage deeply with the academic community and be part of the scientific discourse. There are many opportunities for presentations at internal Machine Learning conferences, which acts as a springboard for publications at premier conferences. We also partner with universities through the Alexa Prize.
