System and method of analyzing audio data samples associated with speech recognition

Abstract

A particular apparatus includes a first buffer that is configured to store multiple audio data samples and a second buffer that is configured to store the multiple audio data samples. The first buffer is coupled to a first processor that is configured to analyze audio data samples to detect a keyword. The second buffer is coupled to a second processor that is configured to initialize a speech recognition engine (SRE) based on the multiple audio data samples. The first buffer has less storage capacity that the second buffer.

Description

I. CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority from and is a continuation application of U.S. Non-Provisional patent application Ser. No. 14 / 573,402, filed Dec. 17, 2014 and entitled “SYSTEM AND METHOD OF ANALYZING AUDIO DATA SAMPLES ASSOCIATED WITH SPEECH RECOGNITION,” the contents of which are incorporated herein by reference in their entirety.II. FIELD[0002]The present disclosure is generally related to speech recognition.III. DESCRIPTION OF RELATED ART[0003]Advances in technology have resulted in smaller and more powerful computing devices. For example, there currently exist a variety of portable personal computing devices, including wireless telephones such as mobile and smart phones, tablets and laptop computers that are small, lightweight, and easily carried by users. These devices can communicate voice and data packets over wireless networks. Further, many such devices incorporate additional functionality such as a digital still camer...

AI Technical Summary

Benefits of technology

This solution allows users to provide keyword / command phrase sentences without delay, as audio data is buffered and processed efficiently, reducing power consumption and maintaining cost-effectiveness by using a smaller first buffer, thus enhancing user convenience and device performance.

Problems solved by technology

Because of the time it takes to prepare the speech recognition capabilities to receive input, there can be a delay between when the user speaks to wake up the mobile device and when the user is able to provide the command.

For example, while the second buffer may be capable of storing audio data associated with an entire command phrase, the first buffer may not have sufficient capacity to store the entire command phrase.
