4. Relevant Information Paragraph:

Dataset from 8800(10 digits x 10 repetitions x 88 speakers) time series of 13 Frequency Cepstral

Coefficients (MFCCs) had taken from 44 males and 44 females Arabic native speakers

between the ages 18 and 40 to represent ten spoken Arabic digit.

5. Number of Instances: 8800

6. Number of Attributes: 13

7. Attribute Information:

Each line on the data base represents 13 MFCCs coefficients in the increasing order separated by

spaces. This corresponds to one analysis frame. The 13 Mel Frequency Cepstral Coefficients

(MFCCs) are computed with the following

conditions;

Sampling rate: 11025 Hz, 16 bits

Window applied: hamming

Filter pre-emphasized: 1-0.97Z^(-1)

8. Missing Attribute Values: None

9. Class Distribution:

Each line in Train_Arabic_Digit.txt or Test_Arabic_Digit.txt represents 13 MFCCs coefficients in

the increasing order separated by spaces. This corresponds to one analysis frame.

Lines are organized into blocks, which are a set of 4-93 lines separated by blank lines and

corresponds to a single speech utterance of an spoken Arabic digit with 4-93 frames.

Each spoken digit is a set of consecutive blocks.

In Train_Arabic_Digit.txt there are 660 blocks for each spoken digit .The first 330 blocks

represent male speakers and the second 330 blocks represent the female speakers. Blocks 1-660

represent the spoken digit "0" (10 utterances of /0/ from 66 speakers), blocks 661-1320 represent

the spoken digit "1" (10 utterances of /1/ from the same 66 speakers 33 males and 33 females

), and so on up to digit 9.

In Test_Arabic_Digit.txt, digits 0 to 9 have 220 blocks for each one. The first 110 blocks

represent male speakers and the second 110 blocks represent the female speakers. Therefore,

blocks 1-220 represent digit "0" (10 utterances of /0/ from the 22 speakers ), blocks

221-440 represent digit "1" (10 utterances of /1/ from the same 22 speakers 11 males and 11

females ), and so on.

Speakers in the test dataset are different from those in the train dataset.

For the Matlab users, files “ *.mat” that represent each block separately are also available.
