UGAkan-ImpairedSpeechData: A Dataset of Impaired Speech in the Akan Language

Female speakers contributed 7,558 files equivalent to 30.99 hours, with most recordings coming from individuals with Cerebral Palsy (4,835 files, 15.66 hours) and Stammering (2,574 files, 13.88 hours). Stroke data was recorded only from male speakers, while Cleft speech samples were collected from both genders, with a higher volume from males. In terms of duration, the audio files vary in length.

The average audio length is 12.46 seconds, with a standard deviation of 7.71 seconds, indicating moderate variability. The majority of audio files range from 6.59s to 16.00s, suggesting a right-skewed distribution. The maximum duration is 60.08s, which exceeds the upper bound of the interquartile range and is likely an outlier.
