Amazon’s customers by advancing the state of the art in Automatic
Speech Recognition (ASR), Natural Language Understanding (NLU)
and Machine Learning (ML).

As part of our speech and language team, you will work alongside
internationally recognized experts to develop novel algorithms
and modeling techniques to build and advance state-of-the-art
spoken language understanding systems. Your work will directly
impact millions of our customers in the form of products and
services that make use of speech and language technology. You
will gain hands-on experience with Amazon’s heterogeneous speech,
text, and structured data sources, and large-scale computing
resources to accelerate advances in spoken language

We are hiring in all areas of spoken language understanding with a special focus on acoustic modeling, language
modeling, finite state methods, etc.
We will also consider candidates without
explicit prior experience in these fields, if they are strong in
machine learning, statistics, and coding, are eager to learn and
have a "can do" attitude.

As a Research Scientist on our team, you will build,
