Optimizing call quality using vocal frequency fingerprints to filter voice calls

A system for optimizing overall network call quality and reducing network bandwidth load, the system comprising:

• a server communicatively coupled to a wireless network, wherein the server includes:
• a voice-call-transmission monitoring module that:
• monitors intercepted voice-call transmissions;
• for each of the intercepted voice-call transmissions, identifies a frequency transmission range, frequency peaks, and harmonics that correspond to a voice in the intercepted voice-call transmissions;
• and
• generates a plurality of vocal fingerprints, each of the plurality of vocal fingerprints corresponding to different individual users and that are usable to specifically identify the voices of the different individual users using the frequency transmission ranges, frequency peaks, and harmonics identified;
• a vocal-fingerprint database storing the plurality of vocal fingerprints, each of the plurality of vocal fingerprints corresponding to different individual users, each of the plurality of vocal fingerprints including the frequency transmission range, the frequency peaks, and the harmonics of the voice of one individual user, wherein the frequency transmission range, the frequency peaks, and the harmonics of each of the plurality vocal fingerprints are usable to specifically identify the voice of the one individual user;
• a vocal-fingerprint referencing module that references the vocal-fingerprint database to:
• identify when the frequency transmission range, frequency peaks, and harmonics of one of the plurality of vocal fingerprints in the vocal-fingerprint database matches any additional intercepted voice-call transmissions;
• and
• determine one or more frequency ranges of the additional intercepted voice-call transmissions that outlie the frequency transmission ranges of the one of the plurality of vocal fingerprints identified as corresponding to the additional intercepted voice-call transmissions;
• and
• a voice-call-transmission optimization module that removes the one or more frequency ranges of the additional intercepted voice-call transmissions that outlie the one or more frequency transmission ranges of corresponding vocal fingerprints of the plurality of vocal fingerprints.

One or more computer-readable storage media having computer-executable instructions embodied thereon are provided that, when executed, perform a method for maintaining and improving voice-call quality over a wireless network, the method comprising:

• via a server:
• monitoring one or more voice transmissions of an individual user;
• analyzing data of the one or more voice transmission to identify frequency peaks and harmonics of the individual user's voice;
• generating a vocal fingerprint that is specific to the individual user, wherein the vocal fingerprint includes a frequency range, frequency peaks, and harmonics that uniquely correspond to the individual user's voice;
• storing the vocal fingerprint that is specific to the individual user on a server;
• receiving another voice transmission of the individual user including a plurality of frequencies;
• comparing the plurality of frequencies to the frequency range, the frequency peaks, and the harmonics of the stored vocal fingerprint that is specific to the individual user;
• filtering outlying frequencies from the voice transmission based on the comparison to the stored vocal fingerprint, wherein outlying frequencies comprise frequencies in the voice transmission that outlie the frequency range of the stored vocal fingerprint;
• and
• utilizing the outlying frequencies to optimize the voice transmission over the wireless network.
