NettetGood values are 300Hz for the lower and 8000Hz for the upper frequency. Of course if the speech is sampled at 8000Hz our upper frequency is limited to 4000Hz. Then follow these steps: Using equation 1, convert the upper and lower frequencies to Mels. In our case 300Hz is 401.25 Mels and 8000Hz is 2834.99 Mels. jolly whole corn priceNettetMel Frequency Cepstral Coefficients - MFCC The most commonly used acoustic features are Mel-scale frequency cepstral coefficient based on frequency domain using the Mel scale which is based on the human ear scale.
