| 发明名称 | Tonal component detection method, tonal component detection apparatus, and program | ||
| 摘要 | There is provided a tonal component detection method including performing a time-frequency transformation on an input time signal to obtain a time-frequency distribution, detecting a peak in a frequency direction at a time frame of the time-frequency distribution, fitting a tone model in a neighboring region of the detected peak, and obtaining a score indicating tonal component likeness of the detected peak based on a result obtained by the fitting. | ||
