Distributed Microphone Arrays in Smart Home (DMASH) Dataset
The AISHELL-DMASH dataset is recorded in real smart home scenarios with two different rooms. The dataset contains50000 hoursspeech data. The recording devices include one close-talking microphone and seven groups of devices at seven different positions of the room. A group of recording devices include one iPhone, one Android phone, one iPad, one microphone, and one circular microphone array with a radius of 5cm. The dataset includes 500 speakers and each speaker visits three times with a gap of 7-15 days. AISHELL-DMASH dataset was transcribed by the professional speech annotators with high QA process, and the accuracy rate of word is 98%, which could be used in research of voiceprint recognition, speech recognition, wake-up words recognition and so on.
