Systems and methods to detect a beginning of input spoken by a user

A system configured to detect a beginning of input spoken by a user, the system comprising:

• a client computing platform configured by machine-readable instructions to:
• obtain, in an ongoing manner, audio information representing sound captured by an audio sensor over an interval of time, wherein the sound conveys input spoken by a user, wherein the audio information includes amplitude values;
• determine an input beginning within the interval of time by determining a sequential set of the amplitude values that have reached or surpassed an amplitude threshold for a period of time, wherein the sequential set includes consecutively measured ones of the amplitude values;
• determine a probable utterance represented by the sound;
• determine an input end based on an amount of time transpiring after the input beginning, wherein the amount of time is based on stored time information associated with the probable utterance;
• extract, from the audio information, an audio portion from the input beginning to the input end;
• analyze the audio portion to determine a function request to execute;
• determine whether execution of the function request requires server resources;
• responsive to determining the server resources are required to execute the function request, transmit the function request to a server;
• and
• responsive to determining the server resources are not required to execute the function request, execute the function request.
