Transcribe Word Time Offsets

This sample demonstrates how to transcribe audio with word time offsets using the Speech-to-Text API.

Code sample

Python

To learn how to install and use the client library for Speech-to-Text, see Speech-to-Text client libraries. For more information, see the Speech-to-Text Python API reference documentation.

To authenticate to Speech-to-Text, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.
