Required. The parent, which owns this collection of custom classes. Format:

`projects/{project}/locations/{location}/customClasses`

Speech-to-Text supports three locations: `global`, `us` (US North America),
and `eu` (Europe). If you are calling the `speech.googleapis.com`
endpoint, use the `global` location. To specify a region, use a
[regional endpoint](https://cloud.google.com/speech-to-text/docs/endpoints)
with matching `us` or `eu` location value.
