Cloud Speech V2 Client - Class Phrase (1.10.0)

Reference documentation and code samples for the Cloud Speech V2 Client class Phrase.

A Phrase contains 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.

List items can also include CustomClass references containing groups of words that represent common concepts that occur in natural language.

Parameters
NameDescription
data array

Optional. Data for populating the Message object.

↳ value string

The phrase itself.

↳ boost float

Hint Boost. Overrides the boost set at the phrase set level. Positive value will increase the probability that a specific phrase will be recognized over other similar sounding phrases. The higher the boost, the higher the chance of false positive recognition as well. Negative boost values would correspond to anti-biasing. Anti-biasing is not enabled, so negative boost will simply be ignored. Though boost can accept a wide range of positive values, most use cases are best served with values between 0 and 20. We recommend using a binary search approach to finding the optimal value for your use case. Speech recognition will skip PhraseSets with a boost value of 0.
