• Recording environment: Studio apartment(moderate reverb), Dance studio(high reverb), Anechoic chamber(no reverb)
• Device: iPhone x, Samsung Galaxy S7
• Recording distance from the source: 0.4m, 2.0m, 4.0m
• Volume(full set): ~3(~290) hours, ~2,000(~190,000) utterances, ~0.5(~107) GB
• Format: 16kHz, 16-bit, mono
• Language: Korean

Pairs of Korean speakers reading scripts with 3 distinct text sentiments (negative, neutral, positive), with 3 distinct vocal sentiments (negative, neutral, positive), are recorded.
The recordings took place in 3 different types of places, which are an anechoic chamber, studio apartment, and dance studio, of which the level of reverberation differs.
And, in order to examine the effect of the distance of mic from the source and device, every experiment is recorded at 3 distinct distances with 2 types of smartphone, iPhone X, and Galaxy S7.

The dataset is a subset(approximately 1%) of a much bigger dataset which were recorded under the same environment as this public dataset.
This sample dataset only contains only a limited amount which contains a single pair of speaker recorded in 3 places, but only at single distance and with iPhone X.
