US 2021/0343277 A1 · SYSTEM AND METHOD FOR OUT-OF-VOCABULARY PHRASE SUPPORT IN AUTOMATIC SPEECH RECOGNITION

Abstract

An electronic device includes an audio sensor, a memory, and at least one processor coupled to the audio sensor and the memory. The at least one processor is configured to receive, via the audio sensor an audio input. The at least one processor is further configured to perform, using an automatic speech recognition (ASR) model and an entity prediction model, out-of-vocabulary prediction of an entity. The at least one processor is further configured to receive an ASR hypothesis including the predicted entity. The at least one processor is further configured to output text including the predicted entity.

6 more elements

A method for out-of-vocabulary phrase support in automatic speech recognition (ASR) comprising:

receiving, via an audio sensor of an electronic device, an audio input;
performing, by at least one processor of the electronic device and using an ASR model and an entity prediction model, out-of-vocabulary prediction of an entity;
receiving an ASR hypothesis including the predicted entity;
and
outputting text including the predicted entity.

2 more elements

A non-transitory computer readable medium embodying a computer program, the computer program comprising instructions that when executed cause at least one processor of an electronic device to:

receive, via an audio sensor of the electronic device, an audio input;
perform, using an automatic speech recognition (ASR) model and an entity prediction model, out-of-vocabulary prediction of an entity;
receive an ASR hypothesis including the predicted entity;
and
output text including the predicted entity.
