The Google Assistant SDK lets you add voice control, natural
language understanding and Google’s smarts to your ideas. Your project captures
an utterance (a spoken audio request, such as
What's on my calendar?
), sends
it to the Google Assistant, and receives a spoken audio response in addition to
the raw text of the utterance.
Google Assistant Service
The Google Assistant Service exposes a low level API that lets you directly manipulate the
audio bytes of an Assistant request and response. Bindings for this API can be
generated for languages like Node.js, Go, C++, Java for all platforms that
support
gRPC
.
Reference code is provided in Python for audio capture, audio playback, and
conversation state management.
