+
+## Dataset Description
+
+AISHELL-3 is a large-scale and high-fidelity multi-speaker Mandarin speech corpus published by Beijing Shell Shell Technology Co., Ltd.
+
+The dataset is designed for training multi-speaker Text-to-Speech (TTS) systems. It contains roughly **85 hours** of emotion-neutral recordings spoken by **218 native Mandarin Chinese speakers**, with a total of **88,035 utterances**.
+
+Auxiliary speaker attributes, including **gender**, **age group**, and **native accents**, are explicitly marked and provided in the corpus.
+
+Transcripts are provided at both:
+
+- Chinese character level
+- Pinyin level
+
+The word and tone transcription accuracy rate is above **98%**, based on professional speech annotation and strict quality inspection for tone and prosody.
