  This paper presents a high quality Vietnamese speech corpus that can be used
for analyzing Vietnamese speech characteristic as well as building speech
synthesis models. The corpus consists of 5400 clean-speech utterances spoken by
12 speakers including 6 males and 6 females. The corpus is designed with
phonetic balanced in mind so that it can be used for speech synthesis,
especially, speech adaptation approaches. Specifically, all speakers utter a
common dataset contains 250 phonetic balanced sentences. To increase the
variety of speech context, each speaker also utters another 200 non-shared,
phonetic-balanced sentences. The speakers are selected to cover a wide range of
age and come from different regions of the North of Vietnam. The audios are
recorded in a soundproof studio room, they are sampling at 48 kHz, 16 bits PCM,
mono channel.
