Hint Boost. 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.
A list of strings containing words and phrases "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 be set to classes for groups of words that represent
common concepts that occur in natural language. For example, rather than
providing phrase hints for every month of the year, using the $MONTH class
improves the likelihood of correctly transcribing audio that includes
months.
