Abstract
Techniques for biasing for entities during automatic speech recognition (ASR) processing are described. In some embodiments, a system implements a gating component that is configured to switch on and off entity biasing on an audio frame basis when processing a spoken input. The gating component processes an audio frame to determine whether the audio frame likely includes a representation of a custom entity. Based on the determination, a biasing component, which is configured to generate entity embeddings, may be turned on or off. In this manner, entity biasing does not run on every audio frame, but only on the audio frames where it can be helpful in increasing ASR accuracy.
