This dataset contains detailed statistical information of a series of audio files, including audio duration, text length, speaking speed, leading and trailing silence, etc. Each audio file is associated with attributes such as text content, audio identifier, sample rate, and provides the maximum, minimum, average values, and percentiles (P99, P75, P50, P25) of these attributes.
