OpenAI patents voice system that knows when you stop talking
OpenAI has filed a patent for a system that processes voice commands in real-time by listening for silence and sentence structure. It identifies when a user has finished a complete thought before sending the audio to an AI engine to generate a response.
In the filing’s own words
Disclosed are systems, apparatuses, processes, and computer-readable media for real-time modes of a generative response engine. The present technology includes different technologies to improve real-time operation to create natural and dynamic interactions to user experiences. A method of the present technology includes receiving audio frames from a client device; determining that a first portion of the audio frames includes speech of a user during a speech instance; transmitting the first portion of the audio frames that includes the speech to a generative response engine; determining that the speech instance has concluded; and sending a signal to the generative response engine to perform an inference operation based on the first portion of the audio frames.
What exactly they claim (claim 1)
1. A computing device associated with a cloud computing service, comprising: at least one network interface; and at least one processor coupled to the at least one network interface and configured to: receive digital audio frames from a client device, wherein a respective digital audio frame has a fixed duration; determine that a first portion of the digital audio frames includes speech of a user during a speech instance; transmit the first portion of the digital audio frames that includes the speech to a generative response engine while the digital audio frames are being received; when a single digital audio frame is identified as being silent, determine, using a conversation classifier, that the speech instance has concluded based on the single digital audio frame being silent and the first portion of the digital audio frames corresponding to an independent clause, wherein the conversation classifier is configured to identify the independent clause based on accumulated audio frames during the speech instance; and send a start signal to the generative response engine indicating to begin an inference operation associated with the speech based on the first portion of the digital audio frames and the single digital audio frame being silent.
