Very Short Pitch Detection and Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240221766 titled 'Very Short Pitch Detection and Coding
Simplified Explanation
The method described in the patent application involves detecting very short pitch lags in speech or audio signals that are shorter than the conventional minimum pitch limitation. This is done using a combination of time domain and frequency domain pitch detection techniques.
- Pitch detection techniques include pitch correlations in the time domain and detecting a lack of low frequency energy in the speech or audio signal in the frequency domain.
- The detected very short pitch lag is coded using a pitch range from a predetermined minimum very short pitch limitation that is smaller than the conventional minimum pitch limitation.
Key Features and Innovation
- Detection of very short pitch lags in speech or audio signals.
- Combination of time domain and frequency domain pitch detection techniques.
- Coding of detected very short pitch lags using a predetermined minimum very short pitch limitation.
Potential Applications
This technology could be used in speech recognition systems, audio processing applications, and voice-controlled devices.
Problems Solved
- Detection of very short pitch lags that are shorter than the conventional minimum pitch limitation.
- Improved accuracy in pitch detection in speech and audio signals.
Benefits
- Enhanced performance in speech recognition systems.
- Improved quality of audio processing applications.
- Better functionality in voice-controlled devices.
Commercial Applications
Potential commercial applications include speech recognition software, audio editing tools, and smart speakers.
