Cascaded Audiovisual Automatic Speech Recognition Models - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240265917 titled 'Cascaded Audiovisual Automatic Speech Recognition Models

The method described in the patent application involves processing a sequence of acoustic frames to generate higher-order feature representations using an audio encoder. These representations are then used in conjunction with corresponding video frames to create audiovisual higher-order feature representations through an audiovisual encoder. A joint network then utilizes these representations to generate probability distributions over possible speech recognition hypotheses.

• Receiving a sequence of acoustic frames
• Generating acoustic higher-order feature representations at each output step
• Creating audiovisual higher-order feature representations for paired acoustic and video frames
• Generating probability distributions for speech recognition hypotheses based on these representations
• Utilizing a joint network for processing both audio and audiovisual representations

Original Abstract Submitted

a method includes receiving a sequence of acoustic frames and generating, by an audio encoder, at each of a plurality of output steps, an acoustic higher-order feature representation for a corresponding acoustic frame in the sequence of acoustic frames. for each acoustic frame in the sequence of acoustic frames paired with a corresponding video frame, the method includes generating, by an audiovisual encoder, an audiovisual higher-order feature representation for the corresponding acoustic higher-order feature frame and the corresponding video frame; and generating, by a joint network, at an output step, a probability distribution over possible speech recognition hypotheses based on the audiovisual higher-order feature representation. the method, for each corresponding acoustic frame in the sequence of acoustic frames not paired with a corresponding video frame, includes generating, by the joint network, at an output step, a probability distribution over possible speech recognition hypotheses based on the acoustic higher-order feature representation.
