چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...
For Pitch Extraction
A synthesis-based method for pitch extraction of the speech signal is proposed. The method synthesizes a numb¢: of log power spectra for different values of fundamental frequency and compares them with the log power spectrum of the input speech segment. The average magnitude (AM) difference between the two spectra is used for comparison. The value of fundamental frequency that gives the minimum...
متن کاملThe Pitch Extraction Method through Spectrum Flattening
The exact pitch(fundamental frequency) extraction is important in speech signal processing like speech recognition, speech analysis and synthesis. However the exact pitch extraction from speech signal is very difficult due to the effect of formant and transitional amplitude. So in this paper, the pitch is detected after the elimination of formant ingredients by flattening the spectrum in freque...
متن کاملMeasuring inharmonicity through pitch extraction
Some experiments are described which illustrate new applications of pitch extraction processing. It is shown that cepstrum and harmonic product spectrum contain distinctive information about the inharmonicity of musical sounds in this case piano tones and that they can be successfully used for illustration of the phenomenon. A way is proposed how to improve the methods, enabling a direct quanti...
متن کاملA pitch extraction reference database
Many pitch extraction algorithms have been proposed in the past. The comparison of these algorithms is difficult because each study tends to be carried out on a unique data set. The purpose of this project is to develop a database for the comparison of these algorithms. This database is based on a core speech module and several additional modules. The core module contains speech and laryngograp...
