text: Once a popular theme of futuristic science fiction or far-fetched technology
forecasts, digital home assistants with a spoken language interface have become
a ubiquitous commodity today. This success has been made possible by major advancements
in signal processing and machine learning for so-called far-field speech recognition,
where the commands are spoken at a distance from the sound capturing device. The
challenges encountered are quite unique and different from many other use cases
of automatic speech recognition. The purpose of this tutorial article is to describe,
in a way amenable to the non-specialist, the key speech processing algorithms
that enable reliable fully hands-free speech interaction with digital home assistants.
These technologies include multi-channel acoustic echo cancellation, microphone
array processing and dereverberation techniques for signal enhancement, reliable
wake-up word and end-of-interaction detection, high-quality speech synthesis,
as well as sophisticated statistical models for speech and language, learned from
large amounts of heterogeneous training data. In all these fields, deep learning
has occupied a critical role.
