Phrase class
A phrases containing words and phrase "hints" so that the speech recognition is more likely to recognize them.
This can be used to improve the accuracy for specific words and phrases, for
example, if specific commands are typically spoken by the user. This can
also be used to add additional words to the vocabulary of the recognizer.
See usage limits.
List items can also include pre-built or custom classes containing groups of
words that represent common concepts that occur in natural language. For
example, rather than providing a phrase hint for every month of the year
(e.g. "i was born in january", "i was born in febuary", ...), use the
pre-built $MONTH class improves the likelihood of correctly transcribing
audio that includes months (e.g. "i was born in $month"). To refer to
pre-built classes, use the class' symbol prepended with $ e.g. $MONTH.
To refer to custom classes that were defined inline in the request, set the
class's custom_class_id to a string unique to all class resources and
inline classes. Then use the class' id wrapped in ${...} e.g.
"${my-months}". To refer to custom classes resources, use the class' id
wrapped in ${} (e.g. ${my-months}). 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
with matching us or eu location value.
