Methods and systems are provided for using a model of human speech quality perception to provide an objective measure for predicting subjective quality assessments. A Virtual Speech Quality Objective Listener (ViSQOL) model is a signal-based full-reference metric that uses a spectro-temporal measure of similarity between a reference signal and test speech signal. Specifically, the model provides for the ability to detect and predict the level of clock drift, and determine whether such clock drift will impact a listener's quality of experience.
System and method for noise estimation with music detection
In a system and method for noise estimation with music detection described herein provides for generating a music classification for music content in an audio signal. The music detector may classify the audio signal as music or non-music. The non-music signal may be considered to be signal and noise. An adaption rate may be adjusted responsive to the generated music classification. A noise estimate is calculated applying the adjusted adaption rate. The system and method may mitigate the noise modeling algorithms being misled by the music components.
Bio-phonetic multi-phrase speaker identity verification
Systems and methods for bio-phonetic multi-phrase speaker identity verification are disclosed. Generally, a speaker identity verification engine generates a dynamic phrase including at least one dynamically-generated word. The speaker identity verification engine prompts a user to speak the dynamic phrase and receives a dynamic phrase utterance. The speaker identity verification engine extracts at least one voice characteristic from the dynamic phrase utterance and compares the at least one voice characteristic with a voice profile the generate a score. The speaker identity verification engine then determines whether to accept a speaker identity claim based on the score.
System and method for content recognition in portable devices
According to a preferred aspect of the instant invention, there is provided a system and method for content recognition in portable devices. Content, preferably audio content is recorded by the instant invention, preferably a sample with a length between 1 and 10 seconds. A fingerprint will be generated from the recorded sample and automatically, and preferably without further user interaction, prompting, notification, etc. (e.g. invisible to the user), compared with the fingerprints in a fingerprint database that is stored locally in the portable device and the result thereafter presented to the user.
Business platform voice interactions
According to some embodiments, a user device may receive business enterprise information from a remote enterprise server. The user device may then automatically convert at least some of the business enterprise information into speech output provided to a user of the user device. Speech input from the user may be received via and converted by the user device. The user device may then interact with the remote enterprise server in accordance with the converted speech input and the business enterprise information.
Multiferroic transducer for audio applications
A multiferroic transducer for an electrical stringed-instrument pickup comprising an upper layer and lower layer of magnetostrictive material and a middle layer of piezoelectric or ferroelectric material disposed between the upper layer and lower layer.
Wind instrument supports
An instrument support for a wind musical instrument includes a bracket configured to be attached to the wind musical instrument, a base section configured to rest on a trunk of a user, and one or more support members spanning a distance between the bracket and the base section. The instrument support further includes a first adjustment mechanism that can be used to adjustably and selectively fix a position of the one or more support members with respect to the bracket and a second adjustment mechanism that can be used to adjustably and selectively fix the distance between the bracket and the base section.
Stringed instrument with fingerboard support
Embodiments are disclosed that relate a stringed instrument having a fingerboard support disposed between a fingerboard and a neck base. For example, one disclosed embodiment comprises a body, and a neck structure extending from the body, the neck structure comprising a neck base, a fingerboard support coupled with the neck base, and a fingerboard coupled with the fingerboard support, wherein the fingerboard support comprises a support surface configured to contact an underside of the fingerboard and a raised side that at least partially covers a lateral side of the fingerboard.
