Aishell is an open-source Chinese Mandarin speech corpus published by
Beijing Shell Shell Technology Co.,Ltd.
<p>
400 people from different accent areas in China are invited to
participate in the recording, which is conducted in a quiet indoor
environment using high fidelity microphone and downsampled to 16kHz.
The manual transcription accuracy is above 95%, through professional
speech annotation and strict quality inspection. The data is free
for academic use. We hope to provide moderate amount of data for new
researchers in the field of speech recognition.
